Routine AC charging
- Use approved, undamaged equipment and a professionally installed home charge point.
- Connect firmly and check that the DOLPHIN shows an active or scheduled session.
- Set a suitable charge target for the journey and follow the handbook guidance for longer parking.
If the rate looks low
Check whether the charger is single- or three-phase, whether a home energy manager is reducing load, and whether another vehicle or appliance shares the available supply.
If charging stops
Record the car and charger messages before resetting anything. Persistent faults or heat need the operator, installer or authorised BYD support.
Step-by-step charging diagnosis
- Photograph the vehicle and charge-point messages before changing any setting.
- Disable every timer, then start one immediate AC session.
- If it starts, stop normally and create one vehicle schedule at least ten minutes ahead.
- If it does not start, test a different known-working compatible post or cable where practical.
- Re-enable only one wallbox, tariff or solar control at a time.
What each result means
- Immediate charging works: the cable and basic AC path are working; investigate timers, authorisation or load control.
- Another post works: the original charge point, installation or operator is the likely focus.
- Every suitable post fails: save the vehicle warning and arrange BYD diagnosis.
- The rate changes during the session: compare battery level, temperature and home load before treating it as a fault.
Safety limit
Never use an extension lead or domestic adaptor unless the exact vehicle handbook and approved equipment explicitly permit it. Stop for heat, burning smell, arcing, damaged pins, water ingress or repeated protective tripping.
