What are the reasons for the inability to charge due to BMS failure in new energy vehicles?

[Wendy]

Blown fuses, poor contact, poor plug contact, and battery end-of-life can all cause BMS failure in new energy vehicles, resulting in the inability to charge: Blown fuse: If the fuse inside the battery is blown, the only solution is to replace the internal fuse of the battery. Poor contact: Poor contact includes many aspects, such as poor contact between the fuse tube and the fuse seat, poor contact between the plug and socket, and poor contact between the charger and power source. These situations can affect the normal charging of the electric vehicle, leading to the battery not charging or not charging fully. Try reconnecting; if it still doesn't work, consider other reasons and address them promptly. Poor plug contact: Poor contact inside the battery is mainly due to connection issues between the positive and negative terminals. Try reconnecting or replacing the wires. If it still doesn't work, you may need to visit a 4S store for repairs. Battery end-of-life: The lifespan of a battery is about 5 years, but frequent incorrect charging methods can cause the battery to fail prematurely. The solution is to replace the battery.
