When an EV charger will not charge
The vehicle, charging equipment, circuit, settings, and service conditions can all affect charging. Start safely.
A failed charge has four suspects: the vehicle's settings, the charger, the circuit feeding it, or, rarely, the utility supply. The first two can be cleared from the driver's seat without opening anything, which is where to start.
Start in the app, not the panel
A charge schedule waiting for off-peak hours, a departure timer, or a charge limit already reached will each stop a perfectly healthy charger, and all three look identical to a failure from the garage. Check the vehicle's screen or app for schedules, limits, and any charge-port error before suspecting hardware.
Reseat the connector fully; a partial latch reads as no session. The charge port's light colors are mapped in the vehicle manual and worth reading once.
Then read the charger's lights
Wall units report through their LEDs: steady for ready, pulsing while charging, and distinct error patterns the unit's manual decodes. An error code noted now saves diagnostic time later, and no lights at all moves suspicion to the circuit.
For a plug-in unit, confirm the plug sits fully in its receptacle, and reset the GFCI (ground-fault circuit interrupter) if one serves it.
Circuit checks from outside the panel
- Find the charger's breaker; a tripped handle often rests in the middle. Reset it fully off, then on, once.
- See whether anything else near the charger lost power too, which implicates the circuit rather than the unit.
- On plug-in installs, study the receptacle face. Discoloration or looseness is a finding, not a detail.
A breaker that trips again as charging begins is protecting against something real: an undersized or shared circuit, a failing receptacle, or a fault in the run. Stop resetting at that point; it has become troubleshooting work.
Heat at the plug ends the session
A plug-in charger on a 14-50 receptacle pulls near the receptacle's limit for hours at a stretch, and receptacles not built for continuous duty can overheat at the blades. A warm plug body, a soft or discolored face, or a melted smell means stop charging there until the receptacle is replaced with one rated for the job.
Scorching, smoke, or burning at the receptacle or panel is a 911 matter first and an electrical repair second.
Charges everywhere except home
Success at public stations acquits the vehicle and points home: the circuit, the receptacle, or the wall unit's configuration. Installer-set current limits are also the usual answer to charging slower than expected; a unit dialed to a lower amperage during setup does exactly what it was told.
Utility outages and what to send us
If the house or the street is dark, charging goes with it; check the outage map and report to the utility rather than an electrician. For the home side, note the charger model, its light pattern or error code, and the breaker's size and behavior.
Send that through Request an Estimate or call (206) 718-3047. If the fix becomes a properly sized circuit or a hardwired unit, EV charger installation covers how that gets planned and permitted.
Common questions
The car charges at public stations but not at home.
That result clears the vehicle and narrows the search to the home circuit, the receptacle, or the wall unit itself. It is one of the most useful facts you can report, so lead with it.
The breaker trips the moment a session starts.
Charging applies a large, sustained load the instant it begins, so a marginal circuit fails at exactly that moment. Undersized wiring, a shared circuit, a worn receptacle, or a fault can each be the cause, and repeated resets prove nothing while stressing all of them.
Charging got much slower than it used to be.
Look at vehicle charge settings, a changed schedule, or a current limit configured in the wall unit; cold batteries also accept charge more slowly in winter. If the slowdown comes with a warm plug, warm breaker, or any odor, stop and have the circuit inspected.
Is a warm plug normal after a long charge?
Slight warmth can occur at continuous load, but distinct heat, softness, discoloration, or smell is failure in progress at the blades. Stop using that receptacle and have it replaced with one rated for continuous charging duty.
