The Quick Answer: Why Your EV Charger Has Stopped Working
If you’re wondering why is my EV charger not working, the most common causes are a tripped circuit breaker, a loose or faulty charging cable, an interrupted power supply, or a software glitch in the charger unit itself. Most of these issues can be identified quickly — and some can even be resolved without calling a tradie.
For Torquay homeowners, EV charging problems are becoming more common as electric vehicle uptake along the Surf Coast continues to grow. Understanding what’s behind the fault can save you time, money, and the frustration of waking up to a flat battery.
Check the Basics First — Before You Panic
It sounds obvious, but the first thing to do is check whether your home has power at all. A blown fuse or tripped residual current device (RCD) in your switchboard can cut power to your EV charger without affecting the rest of your home’s circuits. Head to your switchboard and look for any switches that have flipped to the off position.
Also check the charging cable itself. Inspect it for visible damage, fraying, or bent pins at the connector. A damaged cable is a safety hazard and should never be used — replace it before attempting to charge again.
- Reset your circuit breaker or RCD if it has tripped
- Ensure the charging cable is fully seated in both the vehicle and the wall unit
- Check for any error codes or indicator lights on the charger display
- Restart the charger by switching it off at the wall, waiting 30 seconds, and switching it back on
- Check your vehicle’s onboard charging settings — sometimes the car itself limits charging schedules
Common Reasons Why Your EV Charger Is Not Working
Overloaded Home Electrical Circuit
A Level 2 home EV charger (the standard 7kW wall unit most Torquay homeowners install) draws significant current. If your home’s electrical circuit isn’t adequately rated to handle the load — especially if you’re running other high-draw appliances simultaneously — the circuit will trip as a protective measure. This is particularly relevant in older Torquay homes where the existing wiring may not have been designed with EV charging in mind.
If your circuit keeps tripping repeatedly, this is a sign your electrical infrastructure needs upgrading, not just a reset.
Wi-Fi or App Connectivity Issues
Many modern home EV chargers rely on a Wi-Fi connection to function correctly, especially if you use scheduled charging or smart energy management features. A dropped internet connection or a router reset can interrupt communication between the charger and its companion app, causing the unit to appear unresponsive. Try reconnecting the charger to your home network through the manufacturer’s app before assuming there’s a hardware fault.
Firmware or Software Glitches
Like any smart device, EV chargers receive periodic firmware updates. A failed or incomplete update can leave the unit in an error state. Check the manufacturer’s website or app for pending updates, and follow their recommended reset procedure. This is a surprisingly common fix that many homeowners overlook.
Weather and Environmental Factors
Torquay’s coastal climate brings salt air, moisture, and temperature swings that can affect outdoor EV charger installations over time. Corrosion on terminals, water ingress into an improperly sealed enclosure, or heat-related expansion in wiring connections can all cause intermittent faults. Ensure your charger enclosure has an appropriate IP (Ingress Protection) rating for outdoor use — IP54 or higher is generally recommended for Australian coastal environments.
Faulty Earthing or Wiring at the Installation Point
Poor earthing is one of the less obvious but more serious reasons why is my EV charger not working. If the original installation didn’t meet the requirements set out under AS/NZS 3000 (the Australian Wiring Rules), protective devices may prevent the charger from operating as a safety measure. This is not something you can diagnose or fix yourself — it requires a licensed electrician. You can learn more about EV charger installation standards and options to understand what a compliant setup looks like.
Simple DIY Checks That Are Safe to Do Yourself
There are a handful of checks any homeowner can safely carry out. Resetting the charger, inspecting the cable for damage, rebooting your home router, and checking the switchboard for tripped breakers are all reasonable first steps. Consulting your vehicle’s owner manual to rule out car-side charging restrictions is also worthwhile.
What you should never do is open the charger unit’s enclosure, attempt to rewire any connections, or bypass protective devices. Working on live or high-current electrical equipment without a licence is illegal in Victoria and genuinely dangerous. For broader electrical safety guidance, the Energy Safe Victoria website provides clear information on homeowner responsibilities.
If your charger is installed in your garage alongside other circuits, it’s also worth having a broader electrical safety check done periodically to ensure everything is in order.
When to Call a Professional
If you’ve worked through the basic checks and your EV charger still isn’t functioning, it’s time to call a licensed electrician. You should also call immediately if you notice burning smells, scorch marks around the unit, the charger feels unusually warm to the touch, or your RCD keeps tripping every time you attempt to charge.

Frequently Asked Questions
Why does my EV charger keep tripping the circuit breaker?
Repeated tripping usually means the circuit is overloaded or undersized for the charger’s power draw. It can also indicate a fault within the charger unit itself or a wiring issue at the installation point. A licensed electrician should inspect the circuit and switchboard to determine whether an upgrade is needed.
Can I use a standard power point to charge my EV in an emergency?
Yes, most EVs come with a portable charging cable (Mode 1 or Mode 2) that allows slow charging via a standard 10-amp power point. This is fine for occasional emergency use, but it is significantly slower than a dedicated wall charger and should not be used as a permanent solution due to the sustained load it places on standard household wiring.
How do I know if my EV charger fault is with the car or the charger unit?
Try charging at a public charging station or a friend’s charger. If the car charges normally elsewhere, the fault is with your home unit or its circuit. If the problem follows the vehicle, the issue is likely with the car’s onboard charging system and should be assessed by your vehicle manufacturer or dealer.
Does coastal weather in Torquay affect EV charger reliability?
It can, yes. Salt-laden air and moisture common along the Surf Coast can accelerate corrosion in outdoor-mounted charger enclosures and cable connections over time. Choosing a charger with a high IP rating and having it inspected periodically by a qualified electrician will help maintain reliable performance in coastal conditions.
