Abstract

The embodiment of the invention provides a battery module and a temperature equalization structure. The battery module comprises a thermal management device, a plurality of single batteries and a temperature equalization structure, wherein the temperature equalization structure comprises at least one temperature equalization piece which is in contact with the thermal management device and at least one single battery; the temperature equalization piece is used for conducting hot energy and cold energy of the thermal management device to the single batteries. The battery module and the temperature equalization structure can be used for cooling or heating the single batteries which are in contact with the temperature equalization structure, so that the temperatures of the single batteries are approximate to the temperatures of the internal single batteries.

Description

technical field [0001] The present invention relates to the technical field of battery heat dissipation, and in particular, to a battery module and a temperature equalization structure. Background technique [0002] At present, automobile exhaust emission is one of the main causes of environmental pollution. Since the exhaust emissions of pure electric vehicles are less or even none, the research and development and design of pure electric vehicles are increasingly favored by major manufacturers. The energy of pure electric vehicles mainly comes from battery modules, and the service life of battery modules directly affects the experience of pure electric vehicles. The thermal management device or thermal management method in the prior art cannot adjust the temperature of each single cell well, resulting in a large temperature difference between some single cells of the battery module and the single cells at other positions. SUMMARY OF THE INVENTION [0003] In view of th...
