Problems solved by technology

[0002] In the related art, the battery module and the module installation beam in the existing battery pack are connected through the end plate. It can also be understood that the installation point of the battery module and the module installation beam is located on the end plate. When the battery module For a long time, the installation points of the battery module are not enough, and when the battery cells in the battery module expand, the battery cells have no degree of freedom in the thickness direction
Therefore, the existing battery modules cannot be made long, and the volume utilization rate of the battery modules is not high. At the same time, the expansion space of the battery cells is also limited.

Abstract

The invention discloses a battery module, a battery pack and a vehicle. The battery module comprises a module body, a first side plate, a second side plate, a first fixing lug and a second fixing lug.The first side plate and the second side plate are fixed to the two transverse sides of the module body respectively. The first fixing lugs are fixed to the outer surfaces of the first side plates, and the outer surfaces of the first side plates deviate from the module body. The second fixing lugs are fixed to the outer surface of the second side plate, and the outer surface of the second side plate deviates from the module body. Therefore, by arranging the first fixing lug and the second fixing lug, the mounting points of the battery module can be arranged on the two transverse sides of themodule body, and in the length direction of the battery module, it can be guaranteed that the battery module has an expansion space, so that it can be guaranteed that expansion of the battery module is not limited.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a battery module, a battery pack and a vehicle. Background technique [0002] In the related art, the battery module and the module installation beam in the existing battery pack are connected through the end plate. It can also be understood that the installation point of the battery module and the module installation beam is located on the end plate. When the battery module For a long time, the installation points of the battery module are insufficient, and when the battery cells in the battery module expand, the battery cells have no degree of freedom in the thickness direction. Therefore, the existing battery modules cannot be made long, and the volume utilization rate of the battery modules is not high. At the same time, the expansion space of the battery cells is also limited. Contents of the invention [0003] The present invention aims to solve at least one of the technical prob...
