Problems solved by technology

Most OEMs use different batteries, module types, and box structures for different models, and the degree of sharing is relatively low.
The low degree of sharing not only increases the procurement and production costs of parts, reduces assembly efficiency, but also increases additional parts verification and system verification costs

Abstract

The invention discloses a battery pack device which comprises a length-adjustable box body and at least two standard battery modules sequentially connected in series. All the standard battery modules are installed on a cooling plate. The cooling plate is connected with the box body through an installation support. By designing the length of the box body to be adjustable and arranging the standard battery modules, a required power system is formed among the standard battery modules through series connection, the universality of parts is improved, the assembling process is simplified, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power or power supply equipment in electric vehicles or hybrid vehicles, in particular to a battery pack device. Background technique [0002] The cost of the current power battery system is still one of the bottlenecks hindering the development of new energy vehicles. According to statistics, the cost of the power battery system has accounted for about 50% of the cost of the vehicle. Therefore, how to reduce the cost of the power battery system is particularly critical. Most OEMs choose different batteries, module types, and box structures for different models, and the degree of sharing is relatively low. The low degree of sharing not only increases the procurement and production costs of parts, reduces assembly efficiency, but also increases additional parts verification and system verification costs. Contents of the invention [0003] The object of the present invention is to overcome the ...
