[0002] In recent years, the rapid development of energy storage technology, especially the progress of lithium battery technology as the main energy storage technology, has not only gotten rid of the cumbersome lead-acid technology used before, but also more in line with environmental protection requirements. The energy storage industry has been able to rise on a large scale, and the application of battery energy storage modules has also increased. The energy storage battery module is a key component of the energy storage system. It is a battery combination composed of battery cells connected in series, parallel or series-parallel, and has only one pair of positive and negative output terminals.

[0003] In the battery module, the cover plate plays a role in protecting the battery module. However, the existing cover plates are not well aligned during installation, which makes the installation time-consuming and labor-intensive. In particular, when some cover plates are installed by welding, it is inconvenient to disassemble and repair the battery module. In addition, most of the cover plates can only play a role in protecting the battery module, and do not have good thermal conductivity, which affects the heat dissipation effect of the battery module. In summary, the existing battery module cover plates still have the following problems:

[0004] 1. The cover is troublesome and inconvenient to install or remove; 2. The cover has a relatively simple performance and does not have good thermal conductivity, which affects the heat dissipation effect of the battery module. Utility Model Content
