Battery module capable of improving space utilization rate

Abstract

The invention relates to a battery module capable of improving the space utilization rate. The battery module comprises a battery pack, packing straps, an integrated cover plate, an upper cover, end plates and pressure strips; installation corners are arranged at the outer sides of the end plates; the integrated cover plate comprises a cover plate, a pole piece, a wiring harness and a low-voltageconnector; the low-voltage connector is arranged on the side edge of the cover plate along the thickness direction of a battery through a Z-shaped connecting part; two ends of the cover plate are provided with pole piece connection bases outwards and downwardly in an extension manner along the thickness direction of the battery; the end plates are put at two ends of the battery pack along the thickness direction of the battery; the battery and the end plates are bundled through the packing straps; the integrated cover plate and the battery pack are welded by laser; the integrated cover plate,the upper cover and the end plates are connected in a hooking manner; and the pressure strips and the end plates are connected through a pop rivet. According to the battery module capable of improvingthe space utilization rate disclosed by the invention, the low-voltage connectors and the pole piece connection bases are arranged over the installation corners of the corresponding ends of the module; therefore, the overall height of the module is reduced; and the space utilization rate of the battery module is easily improved.

Description

technical field [0001] The invention belongs to the field of new energy electric vehicles, in particular to the technical field of power battery equipment, and in particular to a battery module for improving space utilization. Background technique [0002] With the introduction of relevant national new energy laws and regulations, as a major measure to alleviate the pressure on energy and the environment - new energy vehicles have been developed rapidly, such as electric buses, electric buses and other commercial vehicles powered by power batteries. The advantages of less environmental pollution and long cruising range have been widely used in our daily life. However, although electric passenger vehicles have been developed, they have not been widely used. The main reason is that passenger vehicles With its small space and compact structure, there is really little space left for the installation of the battery system. Therefore, reducing the occupied space of the battery sys...
