Abstract

The invention provides a power battery assembly. The power battery assembly comprises a box body and a battery module, and the box body comprises a box bottom assembly and a box cover assembly connected to the box bottom assembly in a buckled mode. The box bottom assembly comprises an outer bottom, an inner bottom accommodated in the outer bottom, a foaming buffer supporting layer arranged betweenthe outer bottom and the inner bottom, and a hot plate. The box cover assembly comprises an outer cover, an inner cover accommodated in the outer cover, a foaming buffer supporting layer arranged between the outer cover and the inner cover, and a hot plate. The battery module is mounted in a space defined by the box bottom assembly and the box cover assembly. The power battery assembly has good heat preservation performances, so that the temperature in the box body is maintained in a temperature range suitable for the working of the battery module, and the problems that the power battery assembly is influenced by the ambient temperature during working, and the normal working of the battery module is not facilitated due to overcooling or overheating are solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a power battery assembly. Background technique [0002] Electric vehicles rely on electricity as the power source and replace fuel engines with electric motors. Not only can they achieve zero emissions, low noise, and no pollution, but they can also save a lot of increasingly depleted petroleum energy. With the increasing maturity and application of lithium battery technology for electric vehicles, it has become possible to replace fuel vehicles with electric vehicles. In order to provide the power needed for electric vehicle movement, all existing electric vehicles are equipped with power batteries. The existing power battery mainly includes: a box body and a battery module, the battery module is installed in the box body, and further installed on the applied vehicle body through the box body. However, the existing power battery box has little insulation effect on the exter...
