Electric car charging collision control method and system
TLDR
In this paper, an electric car charging collision control method and system is described, where when the collision strength cannot reach the detonation threshold of airbags but battery security is affected, power can be cut off.Abstract:
The invention discloses an electric car charging collision control method and system; when the collision strength cannot reach the detonation threshold of airbags but battery security is affected, power can be cut off. The system comprises a plurality of collision sensors, a plurality of pressure sensors, an entire car controller, a power battery managing system, a power-off protector, a power battery, an airbag control unit, a dashboard, an alarming device, an airbag control unit and a security airbag system. The collision sensors and the pressure sensors are connected with the entire car controller, the entire car controller is connected with the power battery managing system, the airbag control unit, the dashboard and the alarming device, the power battery managing system is connected with the power battery through the power-off protector, and the airbag control unit is connected with the security airbag system. The system has the advantages that when the collision strength cannot reach the detonation threshold of the airbags but battery security is affected, power can be cut off; security risks result from failures of high-voltage power supply of a car can be avoided effectively, and security of the car and passengers can be protected effectively.read more
