Abstract

The invention provides a battery module. The battery module comprises: a battery pack, a shell assembly and a cover plate assembly, wherein the shell assembly is provided with a first accommodating space for accommodating the battery pack, the cover plate assembly is detachably installed on the shell assembly to shield the battery pack, the cover plate assembly is provided with two tabs connected with the positive electrode and the negative electrode of the battery pack respectively, and at least part of each tab is located on the outer side of the cover plate assembly; and a cooling plate which is provided with a cooling pipeline for cooling liquid to flow in, and the cooling plate is arranged on the inner side of the shell assembly and is in contact with the battery pack. The battery module provided by the invention solves the problem of complex structure of the battery module in the prior art.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery module. Background technique [0002] The development of the new energy industry has enabled battery technology to be widely used. Battery energy storage systems and battery power systems are widely used in new energy vehicles, power station power generation, rail transit and other fields. These applications will have high-power charging and discharging, so the battery will release a lot of heat during the high-rate charging and discharging process in the actual application field. For example, the power plant suddenly increases the load, the car accelerates suddenly and so on. Heat accumulation can cause damage to components, endangering equipment and personal safety. In order to take away the heat, there are different cooling methods in the prior art, such as air cooling, liquid cooling, self cooling and so on. Among these cooling methods, liquid cooling is the fastest and ...
