Where an electric BYD Sealion 7 deserves extra scrutiny
- Thermal management. We look for coolant leaks and stored thermal faults that quietly shorten battery life.
- Software and recalls. Stored fault codes and outstanding software or recall items are checked, as EVs depend heavily on their software.
- Battery state of health. We read the high-voltage battery data to estimate degradation against its original capacity — the single biggest factor in an EV's value.
- Charging port and onboard charger. The port, cables and AC charging are tested for reliable, fault-free operation.
- Range versus rated. We compare the indicated range and consumption with what the car should deliver to spot a weak pack.
