The on-board chargers for new energy vehicles are not universal, mainly due to the following reasons:
1. Voltage and current matching: The universality of on-board chargers for new energy vehicles mainly depends on whether the voltage and current match. Even for chargers of the same brand, it is necessary to check whether their voltage and current meet the requirements of the vehicle battery. Users should avoid assuming that the charger is universal just because it can be plugged in and lights up, as mismatched chargers may cause damage to the battery.
2. Power difference: Chargers of the same power size may be interchangeable, but chargers of different powers cannot be interchangeable. Chargers of different powers have differences in output current and voltage, which cannot meet the charging needs of all vehicle batteries.
3. Charging standards and safety requirements: Strict adherence to charging standards is required during charging, including the magnitude of charging current, charging time, timing of current conversion, and selection of charging termination voltage. Incompatible chargers may not meet these specifications, thereby affecting charging efficiency and safety.
The on-board charger for new energy vehicles is not universal. Car owners should choose a charger based on the specifications and requirements of the vehicle battery, and ensure that the charger meets relevant safety standards and specifications.
