Unable to Charge
Tesla Electric Vehicle
Severity: CriticalWhat Does This Error Mean?
Unable to Charge means the car detected a problem that prevents charging from starting or continuing. This could be a problem with the charger, the cable, the car's charge port, or the electrical supply. Try a different charger or outlet first to isolate the problem.
Affected Models
- Tesla Model 3
- Tesla Model Y
- Tesla Model S
- Tesla Model X
Common Causes
- Faulty or incompatible charging cable or adapter
- Ground fault detected in the home electrical wiring
- Wall outlet providing insufficient voltage
- Charge port sensor or latch failure
- Software glitch in the charging system
- Supercharger station equipment fault
How to Fix It
-
Try a different charging cable or outlet.
If using a home outlet (Level 1), try a different outlet on a different circuit. If using a Wall Connector, try a public charger or Supercharger to isolate the problem.
-
Perform a soft reboot: hold both scroll wheels for 10 seconds.
Software glitches can prevent charging from initiating. A reboot often resolves one-time errors.
-
Check the mobile app for more specific error details.
The Tesla app often shows a more detailed error message than the car's screen. This helps identify whether the issue is the car, the charger, or the electrical supply.
-
Check your home's electrical panel for tripped breakers.
A ground fault or overloaded circuit trips the breaker. Reset the breaker, but if it trips again, have an electrician inspect the circuit.
Frequently Asked Questions
Can a regular wall outlet charge a Tesla?
Yes, but very slowly. A standard 120V outlet (Level 1) adds about 3-5 miles of range per hour. A 240V outlet or Wall Connector (Level 2) adds 20-40 miles per hour.
What if the Supercharger says Unable to Charge?
Try a different stall at the same station — individual stalls can have faults. If all stalls fail, the station may be offline. Check the Tesla app map for station status.
