Got my electric vehicle about 8 months ago and everything worked fine until yesterday. Now when I plug into my level 2 home charger, nothing happens - no lights on the port, no beeping, just dead. The breaker's fine and other devices on that circuit work. Is this an EV-side electrical issue or the charger itself?
Before you assume the worst, do a quick swap test if you have access to another level 2 charger nearby - a friend's or public charging station. Plug your car in there. If it charges normally, your home charger is the culprit. If it still won't recognize anything, you're dealing with a car-side issue. This takes maybe 10 minutes and saves you guessing.
Now here's the thing people sometimes overlook: the charging cable itself can fail independently of both the charger unit and the car. The connector pins corrode, the internal wiring shorts, or moisture gets in there. Try unplugging, waiting a minute, then plugging back in with a firm, deliberate connection - sometimes debris or oxidation on the pins just needs reseating. If you've got a dry cloth handy, gently wipe the connector pins on both the cable end and the port before trying again. I've seen that alone fix "dead" connections that looked like complete failures.
If the swap test shows your car charges elsewhere fine, the home charger is dead and needs replacement or service. If neither of those fixes work, your next move is calling your car's roadside support line - they can often run diagnostics remotely to tell you if it's the vehicle's charging module. Don't start pulling panels or disconnecting battery components yourself; that's dealer territory.
It's hard to say it's definitely an EV-side issue just because the charger side tested okay - the problem could honestly live on either end or even the connection between them. Start by checking your vehicle's touchscreen or app to see if there are any error messages about the charging port or connector status. Some EVs will actively reject a charge session if they detect a fault. Also try a different outlet on the same circuit if you have one, just to rule out a dead outlet specifically.
If the car shows no errors and you've confirmed the outlet itself works, the issue is almost certainly the charger unit or the cable itself. Most level 2 chargers have a test button or LED diagnostic pattern you can check in the manual - some will blink specific sequences to indicate what's wrong (no power, ground fault, etc.). If you're comfortable opening it up, look for a blown fuse inside, but honestly if nothing lights up at all, it's likely a component failure and you're looking at repair or replacement. Worst case, have an electrician verify the outlet's wiring is correct for your charger's specs.
The dead port with zero lights or sounds points more toward the charger itself than your car's charging system. Since other devices on that circuit work fine and the breaker isn't tripped, you've basically ruled out the electrical supply side already. Level 2 chargers have their own logic boards and safety systems that can fail, and an 8-month-old unit going suddenly silent is classic hardware failure rather than an EV-side issue.
Before you assume the charger's toast, try a couple quick things. Unplug it completely for a minute, then plug it back in and see if any indicator lights come on at all - sometimes they need a hard reset. Also try plugging a different vehicle into it if you can borrow one or have access to another EV somewhere, just to rule out the cable itself being the problem. If nothing lights up and another car gets the same dead response, the charger unit needs service or replacement.
If those don't work, contact the charger manufacturer's support and your installer if it's still under warranty. Most home chargers come with a 2-3 year warranty, so you're likely covered. They might walk you through more diagnostics, but honestly if it's truly giving zero response after months of normal operation, it's almost certainly going back for a replacement. Don't mess with the electrical connections yourself - this stuff can be dangerous if you're not trained for it.
