Problems solved by technology

[0005] In view of this, the present invention aims to propose a power battery safety protection system applied to the collision process of electric vehicles. Through the traction effect of this system when the electric vehicle collides, the battery pack will be aligned with the acceleration direction of the vehicle on the slide rail. Consistent displacement, leaving enough space for the battery pack, overcoming the technical problem that the existing battery pack system will fail due to large deformation due to extrusion during the collision process

Abstract

The invention provides a power battery safety protection system applied to an electric vehicle collision process. The power battery safety protection system comprises a vehicle controller, a collisionsensor, a sliding rail, a locking device, a battery pack, and a traction device, wherein the battery pack, the locking device and the traction device are arranged on the sliding rail; the collision sensor is used for collecting the collision acceleration and pressure in different directions, and transmitting a signal to the vehicle controller; and the vehicle controller is fixed to the front cabin of a vehicle through an installing support and controls the locking device and the traction device through a CAN (Controller Area Network) line. The sliding rail device is applied to the safety protection aspect of the battery pack of the electric vehicle, provides a collision reserved space, performs secondary protection on the basis of structural optimization, and is relatively safe and effective; the protection system can realize automation and can be triggered in the first time; and the protection system does not need to be replaced without being damaged, and has relatively good economical efficiency.

Description

technical field [0001] The invention belongs to the field of vehicle collision safety, in particular to a power battery safety protection system applied to the collision process of electric vehicles. Background technique [0002] With the global shortage of petroleum energy and the increasing environmental pollution caused by vehicle exhaust emissions, electric vehicles have become an important direction of today's automobile development due to their advantages in cleanliness and the use of renewable energy. However, due to the excessive pursuit of its development speed in recent years, the safety problem of electric vehicles has become increasingly prominent, and fire and explosion incidents have occurred frequently, which has caused certain doubts in the society about the development and application of electric vehicles, and restricted the promotion and development of electric vehicles. Therefore, the safety problem has become a technical problem to be solved urgently in t...
