Abstract

The invention discloses a power battery safety protection device, which belongs to the technical field of battery safety protection. Solve the problem of insufficient safety protection capabilities of existing power batteries. Including power battery, adhesive layer, protective pad, upper buffer part, lower buffer part, heat insulation layer, protective shell and shell cover, adhesive layer, protective pad and heat insulating layer surround the circumference of power battery, upper buffer part and lower buffer part Placed on the upper and lower ends of the power battery, such an arrangement makes the power battery have the effect of shock resistance and heat protection, and the protective shell and cover play the role of structural support and protection to prevent the power battery from being squeezed when it is hit. The present invention has better shock absorption and buffering effects on the power battery by taking various protective measures. The heat insulation layer effectively isolates the influence of external heat sources on the power battery. When the power battery explodes accidentally, the heat insulation layer can also effectively absorb the explosion shock wave. It has good application value to prevent the power battery explosion from causing damage to people and equipment.

Description

technical field [0001] The invention discloses a power battery safety protection device, which belongs to the technical field of battery safety protection. Background technique [0002] With the rapid development of the new energy vehicle market, power batteries have been widely used. The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. With the extensive application of power batteries, their safety issues have become increasingly prominent, and battery explosion accidents have occurred from time to time, and their safety has become the focus of social attention. Power battery explosions are usually mainly caused by thermal runaway and impact. [0003] At present, the safety protection design of power batteries is mainly improved from the system design, generally through the use of positive and negative materials with...
