Abstract

The invention discloses a battery module, comprising: a first end plate and a second end plate arranged oppositely, a module located between the first end plate and the second end plate, and the first end plate and the second end plate The plate cooperates with the pull rod that fixes the module between the first end plate and the second end plate, cooperates with the first end plate and the second end plate to cover the module, and the pole piece. The present invention is set up through the installation mechanism between the first end plate, the second end plate, the module, the upper cover plate and the pole pieces, so that the battery module structure is small in size, the overall structure is exquisite, compact, safe and reliable, and It can effectively save costs while realizing the lightweight of the module.

Description

technical field [0001] The invention relates to the technical field of battery production and manufacturing, in particular to a battery module. Background technique [0002] With the continuous advancement of the theme of green environmental protection, the use of electric vehicles is increasing year by year. The power battery is one of the core energy storage devices of electric vehicles, and the power battery module has become the main component and key technology of the power battery. Generally, in order to achieve the voltage and power required by electric vehicles, multiple single batteries are usually connected in parallel to form a module, and multiple modules are connected in series, and the series-connected battery modules are installed in the battery box to provide power for electric vehicles . [0003] Most of the lithium battery module cells in the prior art are arranged horizontally, the pole pieces are turned up, and the pole pieces are connected by copper bar...
