There are a few possible reasons why your Tesla is only charging at 6 amps.
- The charger is not compatible with your Tesla. Make sure that the charger is a Level 2 charger and that it is compatible with your Tesla’s charging port.
- The charger is not properly connected. Make sure that the charger is plugged into the wall outlet and that the cable is properly connected to the charger and to your Tesla.
- The charger is overloaded. If the charger is connected to a circuit that is not able to handle the full load of the charger, it will only charge at a slower rate.
- The battery is cold. When the battery is cold, it will only charge at a slower rate. This is because the battery needs to warm up before it can accept a higher charging current.
- The battery is damaged. If the battery is damaged, it may only be able to charge at a slower rate.
If you have checked all of the above and your Tesla is still only charging at 6 amps, then you may need to contact Tesla customer support for help.
Here are some additional tips to prevent your Tesla from charging at a slow rate:
- Use a dedicated circuit for charging your Tesla. This will help to prevent the charger from overloading the circuit.
- Avoid using extension cords. Extension cords can cause voltage drop, which can slow down the charging rate.
- If you are charging in cold weather, precondition the battery before charging. This will help to warm up the battery and allow it to charge at a faster rate.
I hope this helps!
