Does the Volkswagen Phaeton require battery matching when replacing the battery?
1 Answers
Phaeton requires battery matching when replacing the battery, because if the battery is replaced without matching, some functions of the car may not work properly. Introduction to battery matching: After replacing the battery, the ECU still considers it as the previous battery, causing some disabled vehicle electrical appliances to remain turned off. Therefore, after replacing the battery, it is necessary to perform battery replacement matching to register the new battery information. Introduction to the Battery Management System: The Battery Management System (BMS) is mainly designed to improve battery utilization, prevent overcharging and over-discharging of the battery, extend battery life, and monitor battery status. As the battery management system evolves, additional functions may be added.
