You see electric vehicles everywhere in Wollongong now. And if you've just bought an electric car, you're probably wondering which home charger to install.

It's not as straightforward as it should be. There are different power levels, brands, features, and prices. Some electric vehicle chargers cost $700, others $1,600. Some plug into regular outlets, others need three-phase power.

It comes down to what your car can actually handle, what power supply you've got at home, how far you drive each day, and whether you'll actually use smart features.

Here's what actually matters when you're choosing a charger for your home.

The Three Types of EV Charging

Charging Level	Power Output	Range Per Hour	Time to Full Charge	Best For	Installation
Level 1 (Standard outlet)	2.4kW (depending on socket and EVSE limits)	10-15km	24+ hours	Emergency backup only	Plug into regular socket
Level 2 (Home charger)	7kW - 22kW	40km (at 7kW)	6-8 hours	Daily home charging	Hardwired by electrician
Level 3 (DC Fast)	50kW+	300km+	30-60 minutes	Commercial/public only	Not available for homes

Level 1 Charger

Most people start with Level 1, which just plugs into a power point wall socket. However, the charging speed isn't sustainable for daily use, as it takes over 24 hours to fully charge a flat battery.

Level 2 Charger

Level 2 chargers are what almost everyone ends up installing. This type of charger is hardwired and adds about 40km of range per hour at 7kW. Plug your car in when you get home from work, and you'll have a full battery by morning.

Level 3 Charger

Level 3 chargers are the commercial units at shopping centres and service stations. The power draw is too high for residential use, the equipment costs $30,000+.

What Actually Matters When Choosing a Charger

Your Car's Charging Limit

Your EV has a maximum charging speed built in. You can't exceed that, regardless of which home EV charger you install.

A BYD Atto 3 maxes out at 7kW. An MG ZS EV? Also 7kW. Tesla Model 3 can do 11kW. So if you own a BYD and buy a 22kW charger, you've wasted money. Your car still only charges at 7kW.

Check your vehicle specs before buying anything. Here's what common models can handle:

EV Model	Max Charging Speed
Tesla Model 3/Y	11kW
BYD Atto 3	7kW
MG ZS EV	7kW
Hyundai Ioniq 5	11kW
Polestar 2	11kW

Single-Phase vs Three-Phase Power

Most Australian homes have single-phase power. That caps you at 7kW.

Three-phase power is less common. You'll mainly see it in newer homes, bigger properties, or places where someone's paid for an electrical upgrade. With three-phase, you can install 11kW or 22kW chargers.

Open your meter box and look. Single-phase has one thick wire, whereas three-phase has three. Sometimes your electricity bill will tell you too.

The thing is, 7kW handles normal driving fine. Do 50km a day, plug in for eight hours, and you're adding 320km of range. That's more than most people need.

The distance between your switchboard and where you park matters, too. The further apart they are, the more cable your electrician needs to run, which increases the cost.

How Much You Actually Drive

Be realistic about your daily driving. Most overestimate what they need.

Many Wollongong commuters drive around 40-60km per day. Even if you only charge for six hours overnight, a 7kW charger adds 240km of range, which would be more than enough.

You only need faster charging if you're regularly doing 150km+ days or you can't charge your EV battery overnight for some reason.

Smart Chargers vs Basic Ones

Basic chargers have one job: charging your car when it's plugged in.

Smart chargers connect to WiFi and let you control things through an app. You can schedule charging times, monitor energy use, and set charging to occur only during off-peak electricity hours when electricity is cheaper.

Some smart chargers can also work with solar power systems. They'll prioritise charging when your solar panels are producing excess power.

The price difference is usually $300-600. Whether that's worth it depends on your electricity tariff and whether you have time-of-use pricing. If you're on a flat rate all day, smart features don't save you much.

Cable Attached or Not?

Tethered chargers have the cable permanently attached. Untethered ones need you to use your own cable (the one that came with your EV).

Tethered is more convenient. You just pull up and plug in. But if you think you might own multiple EVs or want flexibility down the track, untethered makes more sense.

If you live in a coastal area, tethered cables sit outside exposed to the weather. Salt air and UV wear them down over time. Whatever charger you choose, make sure it's got an IP65 rating or better for weather resistance.

Common Mistakes When Choosing an EV Charger

Buying a Charger Before Checking Your Car Specs

A 22kW charger won't make your 7kW BYD charge any faster. You're paying extra for power your car can't use.

Forgetting to Measure the Cable Reach

Most cables are 5-7 metres. If your charging port ends up on the opposite side of where you mount the charger, you'll have to stretch the cable across your driveway every night.

Not Considering a Second EV Down the Track

 If your partner buys an EV in a few years, can your system handle two chargers running at once? Some smart chargers can split power between multiple cars, which saves you from expensive upgrades later.

Where to Install Your EV Charger

Inside Beats Outside

Garages are best. The charger stays dry, it's more secure, and the weather doesn't beat it up. But if you park outside, just get one rated for outdoor use (IP65 or higher).

Cable length matters more than people think. Most cables are 5-7 metres. Measure the distance from where you'll bolt the charger to where your car's charging port sits when parked. 

Distance From Your Switchboard Matters

The further your charger is from your switchboard, the more the installation costs. The electrician must run a dedicated circuit from the switchboard to the charger. More cable, more digging, more money.

If you're mounting it 30 metres away on the far side of your property, expect a bigger bill.

Salt Air Wrecks Things

Coastal homes are exposed to salt air, so get a charger with stainless mounting hardware and a proper weather rating. Tethered chargers have the cable permanently attached and sitting outside, so UV resistance actually matters.

And don't mount it so low that the plug ends up sitting in a puddle when it rains. About chest height works.

A Few Charger Options to Consider

Charger	Power	Price (unit only)	Best For
Tesla Wall Connector	Up to 11kW	$750-850	Tesla owners, but works with other EVs using an adapter. Built-in WiFi and can share power between multiple units.
Ohme Home Pro	7kW	$900-1,100	Good value for smart features. App control and scheduled charging work well if you're on time-of-use rates.
Zappi	7kW	$1,400-1,600	Best if you've already got panels installed. Built for solar system integration with different eco modes.

Installation adds another $600-1,500, depending on your setup.

You Need an Electrician to Install It

Don't try installing an EV wall charger yourself. It's illegal in NSW, voids your warranty, and is genuinely dangerous.

EV chargers draw serious power. They need their own circuit, proper safety switches, and correctly sized cable. A licensed electrician will:

• Check your system can handle the load
• Install the dedicated circuit with appropriate protection
• Mount and wire the charger properly
• Test everything and give you compliance certificates

Installation costs depend on your setup. If your parking spot is close to the switchboard and you don't need upgrades, expect to pay less. Long cable runs, buried conduits, or three-phase installations cost more.

Most standard installations in Wollongong run between $600 and $1,500.

How to Choose Your EV Charger

Look up what your car can handle first. A BYD Atto 3 maxes out at 7kW. Tesla Model 3 does 11kW. Buying a faster charger won't speed things up if your car can't use it.

Then work out what power you've got. Most homes in Australia run on single-phase power, which means you're stuck at 7kW. Three-phase power lets you go higher, but that's mostly newer houses or bigger properties.

How far do you drive most days? If it's the usual 40-60km around Wollongong, a 7kW charger gives you about 240km overnight. More than you need unless you're regularly covering big distances.

Smart chargers let you set charging times through your phone. The real benefit is charging when power's cheap if you're on time-of-use rates. That can save you hundreds a year. If you pay the same rate all day, smart features don't do much for you.

They also work with panels if you've already got them. But if you don't have off-peak rates or panels, you're probably paying for features you won't use.

A 7kW charger covers daily driving for most people here. Smart or basic depends on whether you'll actually save money with scheduled charging.

Once you've figured out what you need, you'll need a licensed electrician to install it properly.

Get It Installed Properly

What works for your neighbour might not work for you. If they've got three-phase power and a Tesla, that's different to you running a BYD off single-phase in a 1970s house.

Common Questions

How long does installation take?

Usually 2-4 hours if everything's straightforward. If your switchboard needs work or the cable run's a pain, this will obviously take longer depending on your needs. When you speak with your electrician, ask for a timeline when they provide you with a quote.

What's it cost to run?

Say you drive 50km a day. That's about 10kWh of power - roughly $3-4 a day at NSW rates. Works out to about $90-120 a month. Compare that to what you'd spend on petrol for the same distance. Most people charge overnight when rates are cheaper if they're on a time-of-use tariff.

Can two cars share one charger?

They can, but not at the same time unless you've got a load-sharing setup. Most people just rotate - one car tonight, the other tomorrow night. Or install two chargers if your system can handle it.

Do I need council approval?

Not usually for a basic home install. But if you're in a unit or doing major electrical work, check with strata or council first.

Electric vehicle sales in Australia went up 120% in 2023, and Wollongong is no different.

If you have bought an electric vehicle, your house needs to be set up properly before you can charge at home. Having a power point in the garage isn't enough.

Installing a charger can get complicated, especially in older houses. You need to figure out what your electrical system can handle, where the charger should go, what upgrades you'll need, and how much it's all going to cost.

Let's break it down.

Work Out What Kind of Charger You Need

Level 1 vs Level 2 Charging

Most people think all EV chargers are the same. They're not. There's a massive difference between Level 1 and Level 2 charging, and it affects how usable your EV actually is.

Level 1 charging uses a standard 10-amp power point. It adds around 10-15 kilometres of range per hour. That's painfully slow for most people.

Level 2 is what you want. These run at 7kW or more on a dedicated circuit. You'll get 40-50 kilometres of range per hour. A Tesla Model 3 with a 60kWh battery will take around 8-9 hours from empty to full. The same car on Level 1 takes over 24 hours.

How Much Charging Do You Actually Need?

Think about your daily driving. Most people in Wollongong cover 40-60 kilometres a day during work, school runs, and errands.

EVs use roughly 15-20kWh per 100 kilometres. If you drive 50km daily, you're using about 7.5-10kWh. A 7kW charger replaces that in 90 minutes.

Overnight charging works for most people. But if you're doing Sydney trips weekly or driving 150km+ daily, you'll need faster charging. An 11kW or 22kW charger will do the job, but these require three-phase power. Most homes only have single-phase, so you'd need an electrician to check what's possible at your place.

Formula: Daily km ÷ 100 × your EV's kWh/100km rating = daily kWh needed

Check If Your Electrical System Can Handle It

Your Switchboard Matters More Than You Think

Open your switchboard and look at the main switch. It'll show the amperage, which is usually 63A or 80A in most homes around here.

That number matters because a 7kW EV charger needs a dedicated 32A circuit. And everything else in your house is already running off that same service.

If you have any of these, it is time for an upgrade:

• Ceramic fuses instead of circuit breakers
• No safety switches installed
• Rust or corrosion anywhere
• Breakers that trip regularly
• House built before 1990

Many older Wollongong homes have outdated switchboards that can't handle an EV charger. If your switchboard is old, you'll need to upgrade it first.

Can Your Home Handle the Extra Load?

Your main switch might say 80A. At 230V, that's about 18.4kW total capacity. Add up what runs at the same time during peak hours: air con (3-5kW), oven (2-3kW), hot water (3-4kW), maybe a pool pump (1-2kW), plus general stuff (2-3kW).

You're already at 11-17kW. Add a 7kW charger and you're pushing it.

Most electricians will do a load calculation when they assess your place. We measure what your home actually uses and figure out if the existing service can handle an EV charger. If it can't, you need a service upgrade through Endeavour Energy.

Endeavour Energy upgrades take 2-4 weeks, depending on where your house sits and what work's involved.

The Dedicated Circuit Requirement

EV charging stations must run on their own circuit. Nothing else on that line.

For a 7kW charger:

• 32A circuit breaker
• Type A RCD (that's a safety switch)
• 6mm² cable minimum
• Proper earthing and protection

Cable size goes up if you're running a long distance from the switchboard to where the charger sits. Your electrician calculates this based on Australian Standard AS/NZS 3008 to prevent voltage drop.

In NSW, safety switches are mandatory. If your board doesn't have them, they must be installed along with your home EV charger.

Where Should the Charger Actually Go?

Garage or Outside?

Most people put chargers in the garage or under a carport. It's protected, usually close to the switchboard, and keeps everything tidy.

You can install outside, but you need the right IP rating. With Wollongong's coastal climate, you want at least IP54, better yet IP65. Otherwise, you'll get corrosion and water damage.

Garages work better for most people because:

• No weather exposure
• Usually closer to the switchboard (cheaper installation)
• Easier cable management
• Charger lasts longer

Installing the charger outdoors makes sense if you park on the street side of your house, or your garage is nowhere near where you actually park.

Distance from the Switchboard Changes the Price

Every metre of cable adds cost. If the EV charger is being installed close to your switchboard (10-15 metres), it is an easy job. Further out will cost you more. Long distances mean more work: trenching, protective conduit, junction boxes, or upgraded cable to handle voltage drop.

The maximum practical distance is about 50 metres for residential jobs. Beyond that, you get a significant voltage drop even with big cables, and the cost goes up.

Think About Where Your Car's Charging Port Is

EV charging ports aren't standardised. Tesla puts theirs on the rear left, Nissan Leaf at the front and Hyundai Ioniq 5 rear right.

Charging cables are typically 5-7 metres. Where will you park your car? Where will the port be? Mount the charger so the cable reaches without stretching across walkways.

If you own more than one electric vehicle, put the charger where it can reach both parking spots, or add a second one while your electrician is on-site. It's cheaper than a second callout.

Get a cable holder too. It keeps cables off the ground and makes a difference.

What to Do Before the Electrician Shows Up

Paperwork and Approvals

All electrical work in NSW needs a Certificate of Electrical Compliance. Your electrician sorts this out and issues it after the job's done and inspected.

Wollongong Council doesn't need separate permits for electric car chargers in most cases. It's minor electrical work. But if you're in a unit or townhouse with strata, there's more information below in the Rentals and Strata section.

Get Your Switchboard Assessed First

Book an electrical assessment before you get installation quotes. This tells you what electrical upgrades you need.

Common upgrades we see in Wollongong:

• Switchboard replacement - Old ceramic fuse boards get swapped for modern circuit breaker boards.
• Safety switches - Depending on what you currently have installed.
• Main switch upgrade - Going from 63A to 80A or 100A.
• The dedicated EV circuit - This is usually included in the installation quote.

The assessment takes maybe 30-45 minutes. You will get a written report explaining what's needed and why.

Clear the Area and Document Everything

Before installation day, clear the space where the charger will go. Move your car and anything near the switchboard. The electrician needs clear access between both spots.
Take photos of where the charger will mount and measure the distance to your switchboard. Note any

obstacles in between—walls, gardens, or paths that might complicate the cable run.
If trenching's needed, call 1100 (Dial Before You Dig) to locate underground services. Mark irrigation lines or garden lighting cables. Clear garden beds along the cable route.

What It Actually Costs in Wollongong

A standard home EV charger installation includes labour, materials like cable and conduit, and electrical work. The price depends on your home's setup.

If your switchboard is ready, the charger location is close (within 15 metres), and there's no trenching needed, the job is straightforward.

But costs go up if you need:

• A switchboard upgrade
• Trenching to run cable underground
• Conduit for exposed cable runs
• An Endeavour Energy service upgrade for more power capacity
• A higher-spec charger unit with extra features

Most Wollongong homes need at least one of these extras. A switchboard upgrade is the most common.

The NSW government runs electric vehicle incentives that can reduce your costs. They change frequently, so check what's available before you book.

How Long Does It Take

Most straightforward installations take 3-6 hours and get done the same day. But if your switchboard needs upgrading, the job spans an additional 4-6 hours. We do the upgrade, get it inspected, then come back to finish the charger once it's approved.

Endeavour Energy service upgrades slow things down more. They need to schedule and do their work first, which adds 2-4 weeks to the timeline. Your electrician handles the coordination.

You'll get your Certificate of Compliance within 2 business days after everything's finished.

One booking tip: avoid December to February if you can. April to October usually has better availability.

Smart Chargers vs Standard Ones

Standard home EV chargers work like a phone charger—plug in and they start charging. That's it.

Smart chargers connect to WiFi and give you more control:

• Schedule charging for off-peak rates (10pm-7am in NSW when electricity's cheaper)
• Monitor your home's total power use and adjust charging so you don't overload
• Track usage and costs
• Start/stop from your phone

Choosing an Electrician Who Knows EV Chargers

Not every electrician has EV charger experience. Check they're:

• Licensed in NSW (Service NSW website)
• Carrying public liability insurance
• Familiar with AS/NZS 3000/3008 and NSW Installation service rules requirements
• Experienced with EV installs (ask how many)

Good ones offer detailed quotes, free assessments, clear upgrade explanations, 12-month warranties, and have Wollongong reviews.

Questions Worth Asking

1. How many EV chargers have you installed around Wollongong?
2. What brands do you recommend and why?
3. Does my switchboard need work?
4. What's the total cost, including potential upgrades?
5. How long will it take?
6. What warranty comes with the installation?
7. Will I need an Endeavour Energy upgrade?
8. What certification will I get?
9. What maintenance is needed?

Red Flags

• Quoting over the phone without seeing your switchboard.
• Can't explain what upgrades are needed.
• No written quote or warranty.
• Pressuring you to book immediately.
• Way cheaper than everyone else (corners get cut somewhere).

Making Sure It's Safe and Legal

Australian Standards for EV Chargers

Your installation has to meet AS/NZS 3000, 3008, and 3123. That's the wiring rules, cable selection, and EV-specific standards.

If the charger is being installed outside, you need at least an IP54 rating. Go IP65 if you're near the coast because salt air's a problem.

Your electrician will sort out circuit breakers, RCD protection, earthing, cable sizing, and weatherproofing if it's an outdoor installation.

After Installation

You'll get a Certificate of Electrical Compliance when the job's done. Keep it safe—you'll need it for insurance, council records, and when you sell the house.

Your electrician tests everything before handing over the keys. They check the safety switches, earthing, and that power's flowing correctly.

Maintenance is simple. Keep the charger clean and cables out of the way, that's it.

Dealing with Tricky Situations

Older Houses

Pre-1990 homes often have wiring that wasn't designed for modern loads. Even if your switchboard looks okay, the house wiring might be undersized or deteriorating.

Switchboards from the 70s and 80s sometimes have asbestos backing. Your electrician will spot it and handle it safely during the upgrade. Older homes also tend to have longer cable runs because garages were added later or sit further from the main board. That pushes the cost up, but it's manageable.

Heritage properties sometimes have restrictions on external electrical work. Garage installs usually dodge this. But if you're mounting outside, check with the council first.

Rentals and Strata Buildings

Renters will need landlord permission. Some landlords will say yes because it adds value and appeals to EV drivers (offering to pay also helps). Sometimes they'll agree if the charger stays with the property.

Portable chargers plug into 15A outlets. Slower, but no installation hassles.

If you are with strata, you will need body corporate approval. Write to your owners' corporation with:

• What charger do you want, and where
• Confirmation that it's in your parking space
• The electrician's assessment
• Proof that it meets Australian Standards

Most strata applications get approved these days. Just budget 4-8 weeks for the process.

Getting Started with Your EV Charger Installation

You'll need to sort out a few things before installing an EV charger. Check what your electrical system can handle, pick a charger and work out where it'll go, maybe upgrade your switchboard, and get an electrician who's done these installs before.

Most Wollongong houses are fine for an EV charger without much fuss. Older places might need the switchboard updated, but that's not a bad thing. It makes everything safer anyway.

Common Questions About EV Charger Installation in Wollongong

Do I need council approval for an EV charger in Wollongong?

No. Wollongong Council doesn't require separate approval for residential EV chargers. It's minor electrical work. But if you're in a strata building, you need body corporate approval first. Your electrician handles all the electrical certifications.

How long does installation take?

Straightforward job? 3-6 hours, done in a day. Switchboard upgrade? 4-6 hours for inspections. Endeavour Energy service upgrade? Add 2-4 weeks for their scheduling.

Can I install a charger if I'm renting?

You need landlord permission for anything permanent. Some landlords approve it because it adds property value. If they refuse, look at portable chargers that plug into existing outlets. They are slower, but no installation is needed.

How much will it add to my electricity bill?

Depends on how much you drive. Someone doing 50km daily uses about 7-10kWh, which costs roughly $2-3 per day at standard rates. Charge overnight on off-peak rates, and that drops to around $1-2 daily. Most people spend $30-55 monthly—way less than petrol.

Do all chargers work with all EVs?

Yes, if they use Type 2 connectors (standard in Australia). All new EVs sold here since 2020 use Type 2. Older models like early Nissan Leafs use Type 1, but adapters exist.

Can I do it myself?

No. In NSW, licensed electricians must do all electrical work. DIY electrical work is illegal, dangerous, and voids your insurance.

Are there government rebates?

NSW EV rebate programs change regularly. Currently, there are rebates for EV purchase, but limited programs for home charger installs. Check the NSW Government EV website.

As electric vehicle adoption continues to surge across the country, so do more Aussie households plugging in their cars at home. Data from the Electric Vehicle Consortium (EVC) shows that in 2024 alone, Australians purchased around 114,000 new battery electric and plug-in hybrid vehicles, smashing the previous record of 98,000 sales in 2023.

As demand grows, so does the need to maintain home charging set-ups. For new or aspiring EV owners, it's important to know that a well-cared-for EV charger not only ensures safe and efficient charging, but also helps extend the life of your unit and avoids costly repairs.

This guide will cover practical maintenance tips to get the most out of your EV charger.

Why Maintaining Your EV Charger Matters

Firstly, you may not have even considered that EV chargers need maintenance. Perhaps you thought they were mostly set-and-forget. Unfortunately, this is not the case. Just like any electrical device, especially ones exposed to the elements or regular use, a little upkeep goes a long way.

How exactly?

When you have DC fast charger, portable charger, or AC power, regular maintenance helps make your EV home charger last longer. It also ensures safe and efficient charging, and reduces the risk of overheating. Most importantly, staying on top of minor wear and tear can help prevent costly repairs or even a full replacement down the track.

Best Practices for EV Charging Maintenance

Building a simple habit of regular checks can save you a lot of hassle in the long run. A quick visual inspection once a week or so can help catch issues early. Things to keep an eye out for:

• Frayed cables;
• Cracked casings;
• Loose plugs;
• Signs of rust around wall-mounted units.

Was your charger installed on a dedicated circuit by a licensed electrician? This is important because it avoids overloading your home’s electrical system, as well as ensuring safer, more reliable charging.

We recommend avoiding using low-quality or mismatched charging equipment. While cheaper, it can reduce efficiency and even void warranties. Stick with certified, compatible charging equipment designed for your EV and local standards. The peace of mind is worth it alone.

Finally, try to charge during off-peak hours when electricity is cheaper and the grid is less stressed. Not only is it more economical, but it’s better for faster charging your EV, and for your EV charger longevity too. Again, it's all about establishing habits. Like brushing your teeth, make it a routine to plug in your EV overnight.

Quick Pre-Maintenance Safety Checks

Before you do any maintenance, follow these simple steps to stay safe and spot early signs of trouble:

Step 1: Turn Off the Power

Safety first. Switch off the EV charger at your home’s switchboard to avoid electric shock during inspection or cleaning.

Step 2: Inspect Cables and Ports

Look for frayed wires, cracked insulation, loose connectors, or signs of wear on the charging plug and socket.

Step 3: Check for Water, Dust, or Insects

Make sure there’s no water pooling around the unit, no dust clogging vents, and no signs of insects or pests, especially in outdoor set-ups.

Step 4: Look for Signs of Overheating

Watch for discolouration, burn marks, warped casing, or any plastic smells that could indicate heat damage or internal faults.

Cleaning Your Home EV Charger Safely

Just like you give your car a little TLC whenever you wash or vacuum her, so you should with your EV charger. Keeping it clean helps prevent grime, salt, or debris from interfering with its performance.

• Use a soft, non-abrasive cloth with a mild detergent and water solution to gently wipe down the exterior.
• Never spray water or cleaning products directly into charging ports or electrical components. Instead, use a damp cloth here.
• Adjust your cleaning frequency based on your environment. If you live in a coastal area with salt air or lots of dust inland, check and clean the charger more regularly. As a rule of thumb, aim for about once a month. For indoor or sheltered units, every quarter is usually enough.

Loving your EV means regular, careful cleaning of your charger also. It can extend the life of your unit and keep it looking and working like new.

Software Updates & Smart Charger Diagnostics

Modern EV chargers, especially those paired with smart charging features in vehicles like Tesla, BYD, Hyundai IONIQ, or MG ZS EV, often come with built-in software that requires occasional updates to stay efficient and compatible.

How to Check for Updates

Most smart chargers allow you to check for firmware updates via a companion app or web portal. Some brands even update automatically over Wi-Fi. It's important because keeping your charger's firmware up to date helps improve performance, ensures compatibility with newer EVs, and may patch any safety or efficiency bugs. If your charger has LED status lights, learn what they mean. Blinking red might signal a fault, while a flashing blue could simply mean it's updating or in standby mode.

When in doubt, check the user manual or the manufacturer's app for diagnostic information, or refer to Google or YouTube, where you will likely find an answer.

When to Call a Licensed Electrician

There might be situations where a quick clean or cable check just won’t cut it, and you need to call in a licensed electrician.

First, if you notice a burning smell, get on the phone ASAP. Additionally, if you see discoloured casing or exposed wires, stop using the charger immediately. These are potential signs of burning and safety hazards.

Now, if your charger cuts out mid-charge, won’t start consistently, or trips your circuit breaker, there may be an issue with the wiring or load that needs professional diagnosis. We suggest not trying DIY when there's electronics involved, unless you've been trained.

Finally, we're in Australia, so it's important to stay compliant unless you want an infringement. In Australia, all EV charger installations and repairs must meet strict electrical standards. Having work done by a licensed electrician provides peace of mind that your set-up is compliant with regulations and protected by your home insurance coverage.

If in doubt, don’t risk it. A licensed electrician can safely test, repair, or replace your charger and ensure everything is up to specifications. The investment can save you from bigger issues (and bigger bills).

Seasonal Considerations for Aussie Homes

Australia’s weather can be unforgiving, especially within the last decade of so. If it's not bushfires, it's floods or epic storms. As such, it’s important to consider how the seasons affect your EV charger.

If you experience extreme heat in summer, we're talking 40+ degree days, it can stress electrical components. This is why it's smart to install your charger in a shaded and well-ventilated area to reduce overheating and prolong its lifespan. Additionally, try to avoid charging during the middle of these extreme heat days.

For flooding and storms, ensure your charger is mounted well above ground level and protected from potential water ingress. During storms, unplugging your charger (if safe to do so) can prevent surge damage. For areas like Sydney and Brisbane, avoid charging during your intense storms.

In high-risk bushfire zones, avoid installing chargers near flammable vegetation or in areas without adequate clearance. Use non-combustible mounting surfaces and follow local safety regulations to minimise fire hazards.

Planning for the seasons helps keep your charger safe, compliant, and running efficiently all year round. This is where an experienced electrician can provide invaluable advice.

Common Mistakes to Avoid

Here are the most common mistakes we see people make while maintaining their EV charger:

• Neglecting regular checks;
• Cleaning while it's connected;
• Letting water or cleaning products enter ports or electrical components;
• Using a pressure washer (can do more harm than good);
• Using extension cords;
• Charging during extreme weather;
• Ignoring warning signs such as charger flashes or your EV app shows a fault.

And, for your car battery’s health, avoid letting it fully deplete before charging. This will improve the battery life.

Future-Proofing Your Charger

As EV ownership continues to grow, it’s smart to future-proof your charger for long-term use. You may use it for your next EV, after all. On that note, make sure your charger is compatible with a wide range of EVs, not just your current model. Moreover, it's worth investing in a unit that supports higher charging capacities to handle future EV models and potential multiple-vehicle households.

Optimise your charging routine by setting habits. You can use timers as reminders for using off-peak rates, and pairing with smart home systems for greater efficiency. And, if you're looking to cut running costs and boost sustainability, consider integrating solar power. It's a great feeling knowing that your EV is being powered by free and clean energy from the sun.

You’ll need a dedicated circuit, an accessible installation point, and a licensed electrician to ensure your electric car home charger meets safety and capacity requirements.

Is it OK to leave my EV charger plugged in all the time?

Yes, it’s perfectly safe to leave your EV charging cable plugged in to charge your EV, as long as it's installed and the charging speed is functioning properly.

You've probably noticed the increasing prevalence of electric vehicles (EVs) on the road. The likes of Teslas and other models are rapidly becoming the future of transportation, but potential buyers still have reservations about making the switch from combustion engine cars (petrol-powered) to electric.

One of the most common questions potential buyers ask is: how fast do electric vehicles charge? The answer depends on several factors. So, in this guide, we’ll break down EV charging speeds, explain the different charging levels, and specify how long it takes to charge popular electric car models.

What Affects EV Charging Speed?

EV charging speed isn’t one-size-fits-all—it depends on several key factors.

Battery Size and Capacity

Just like a bigger fuel tank takes longer to fill, a larger battery takes longer to charge. A high-capacity EV battery will need more time to reach full charge compared to a smaller one. The benefit, however, is that larger batteries store more electricity and thus come with longer range.

Charger Type and Level

Charging speed varies depending on whether you’re using a slow Level 1 charger, a faster Level 2 charger, or an ultra-fast DC charger.

State of Charge (SoC) and Battery Health

Charging slows down as the battery gets fuller and older batteries may not charge as efficiently as new ones.

EV Charging Levels Explained

Not all EV chargers are the same. There are three levels, and the speed at which your car charges depends largely on the type of charger you’re using.

Level 1 Charging (Slow Charging)

This is the most basic type of EV charging, using a standard household outlet. This is what you would use at home if you do not have a proper EV charger installed. It’s convenient but slow taking anywhere from 8 to 40 hours to fully charge a battery. Most EV users rely on this type of charger for overnight charging.

Level 2 Charging (Standard Charging)

This next step up is Level 2 chargers, which you can have installed at home by a quality Wollongong electrician, usually inside or around your garage. Level 2 uses a 240V power source, cutting charging time to around 4 to 8 hours. Most EV brand dealerships offer Level 2 home chargers as an optional purchase when buying your EV. Besides being in homes, you can also find Level 2 EV chargers installed at workplaces and public charging stations.

DC Fast Charging (Rapid Charging)

The "Rolls Royce" of charging, or should we say, the "Tesla" of chargers. DC charging is for those who demand a quick top-up. DC fast chargers (also known as rapid chargers) use direct current (DC) to charge EV batteries more quickly, bypassing the car's onboard converter. As a result, DC charging speeds can charge an EV to 80% in as little as 15–45 minutes. These high-powered chargers are found at highway rest stops, shopping centres, and EV charging networks like Tesla Superchargers.

Charging Times for Popular Electric Vehicle Models

The type of electric vehicle model will influence charging time. Here's a handy comparison.

It's important to note that these times are averages and can vary based on factors like the vehicle's battery capacity, charger efficiency and the vehicle's max charge rate.

Tips to Optimise EV Charging Time

There are a few hacks you can implement to help optimise EV charging time.

1. Use Level 2 Charging Whenever Possible

Find opportunities for Level 2 charging whenever possible, even if it's not for a full charge as it will reduce your charging time on a Level 1 charger later.

2. Charge Overnight

Most electric car drivers make a habit of plugging in their cars overnight, whether they use Level 1 or Level 2 charging. This is an off-peak time which helps you avoid high electricity rates. Furthermore, your battery gets charged while sleeping, without affecting your daily schedule.

3. Don’t Always Fully Charge

To maintain battery health, it’s generally best to avoid charging to 100% unless needed for long trips.

4. Avoid Deep Discharges

On the flip side, try to keep your battery’s charge level above 20% to avoid putting excessive strain on the battery, which can improve its lifespan.

5. Keep Battery Temperature Optimal

Extreme temperatures (both hot and cold) can slow down charging times and affect battery life. As the car regularly heats, try to park in shaded or temperature-controlled areas whenever possible. Underground carparks are ideal.

Future of EV Charging Speeds

The future of EV charging is looking incredibly promising with innovations coming through regularly. These include ultra-fast charging technology and even wireless charging systems that could significantly reduce charging times. Who knows, one day it might be as quick as filling your car up with petrol.

As the demand for EVs grows, the need for reliable charging infrastructure will continue to rise.
