A temperature-adjustable electric vehicle battery assembly

Abstract

The invention relates to the technical field of an electric vehicle, and discloses an electric vehicle battery pack with a temperature regulation function. The electric vehicle battery module comprises a battery box and a box cover, wherein an electric connector is arranged at the side surface of the battery box; a heat radiation plate is arranged on a bottom plate of the battery box; a heat conduction plate is arranged at the upper side of the heat radiation plate; the periphery of the heat conduction plate is fixedly connected with the inner wall of the battery box; a plurality of vertical heat conduction separation plates are arranged on the upper side surface of the heat conduction plate; a vertical heat conduction passage is arranged in the heat conduction separation plate; storage battery units are arranged in each battery installing cavity; two semiconductor refrigeration sheets are arranged at the bottom of the heat radiation plate; the hot end of the semiconductor refrigeration sheet is connected with the heat radiation plate through heat conduction glue; the cold end of the semiconductor refrigeration sheet extends out of the bottom plate; a heat insulation plate is arranged between the heat radiation plate and the bottom plate. In cold winter, the space inside the battery box is heated through the hot end of the semiconductor refrigeration sheet, so that the proper work temperature of the storage battery unit is maintained; the duration capability is further improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle battery assembly whose temperature can be adjusted. Background technique [0002] With the progress of society, electric vehicles are becoming more and more popular on domestic roads. Electric vehicles are usually divided into electric vehicles and electric bicycles. Electric vehicles in this application refer to electric bicycles; electric bicycles use batteries as power sources for the motors in the wheels Power supply, the speed of electric vehicles is faster than that of bicycles, and it is very environmentally friendly, which brings great convenience to people's travel. For electric vehicles, the biggest limitation at present is the power limit of batteries. Most electric vehicles use lead-acid batteries. People who ride electric vehicles for a long time will easily find that the power of electric vehicles is not durable in winter. The power su...
