Abstract

The invention discloses a power battery safety protection device, and belongs to the technical field of battery safety protection. The problem is solved that a current power battery safety protectioncapacity is insufficient. The power battery safety protection device comprises a power battery, adhesive layers, protection pads, upper buffer parts, lower buffer parts, heat insulating layers, a protective shell and shell covers. The adhesive layers, the protection pads, the heat insulating layers surround the circumference of the power battery, the upper buffer parts and the lower buffer parts are arranged at the upper and lower end faces of the power battery so that the power battery has anti-seismic and thermal protection effects, the protective shell and the shell covers have structure support and protection effects to prevent the power battery from being extruded when the power battery is impacted. Through adoption of various protection measures, the power battery safety protection device has good vibration absorption and buffering effect on the power battery, the heat insulating layers can effectively isolate the influence of an external heat source on the power battery, when the power battery is explored by accident, the heat insulating layer can effectively absorb the exploration shock waves and avoid damaging for human bodies and devices due to exploration of the power battery, and therefore, the power battery safety protection device has a good application value.

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...
