Abstract

The invention discloses a protection device for an electric automobile accumulator. The protection device comprises an accumulator placing box; a mounting plate is arranged on each of the left side and the right side of the bottom of the accumulator placing box; a plurality of shock absorbing springs are arranged at the bottom inside the accumulator placing box; a lower supporting plate is arranged at the top of the shock absorbing springs; and a lower rubber plate is arranged at the top of the lower supporting plate. The left side wall and the right side wall inside the accumulator placing box are also provided with shock absorbing springs; a side supporting plate is arranged at one end of the shock absorbing springs on the side walls; and a side rubber plate is arranged on one side of the side supporting plate. An accumulator body is placed between the lower rubber plate and the side rubber plate; a dry powder extinguishing agent box is arranged at the bottom of an upper cover and between upward pressing springs. A dry powder extinguishing agent is arranged in the dry powder extinguishing agent box. When a major collision accident happens, the dry powder extinguishing agent box can be broken so that the accumulator placing box can be filled with the dry powder extinguishing agent, thereby preventing liquid in the accumulator from flowing around and effectively avoiding the occurrence of fire.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery protection device for electric vehicles. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Pure electric vehicles, compared with fuel vehicles, the main difference (difference) lies in the four major components, drive motor, speed controller, power battery, and on-board charger. Compared with gas stations, it consists of public ultra-fast charging stations. The quality difference of pure electric vehicles depends on these four components, and its value also depends on the quality of these four components. The use of pure electric vehicl...
