BYD SEAL: Battery still does not charge after connecting the charger
Symptoms
- The charger is connected, but the battery does not charge normally. [1]
Possible causes

Checks
- Check SOC, temperature, low-voltage power supply and charging equipment indicators; stop charging if the vehicle indicates a fault. [1]
What to do
- Address only the confirmed troubleshooting branch or contact a service provider. Do not recommend an OBC or high-voltage traction battery assembly on this basis. [1]
Applicability and limits

- Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name
