What are the key points of BYD product protection?

High voltage system safety protection. The focus of BYD product protection is on the safety protection of high-voltage systems; collision high-voltage disconnection is used in BYD pure electric vehicles as a very effective means of disconnecting high-voltage systems. As soon as the vehicle collides, the airbag ECU will send The collision signal is sent to the controller, and the controller immediately cuts off the high-voltage power supply of the battery, and simultaneously triggers the active and passive discharge in the high-voltage system to release the high-voltage electricity in the high-voltage system; by cutting off the high voltage and active and passive discharge through the collision, the entire vehicle can be quickly discharged The body and high-voltage system are not electrified. Even if the impact is accompanied by damage to the high-voltage system, the body is not electrified, so the safety of the high-voltage system in the event of a collision can be fully guaranteed; technical means such as collision interruption of high voltage, active and passive discharge can fully ensure the safety of the high-voltage system in the event of a collision. high voltage safety.
