Description

Technical field:

[0001] The invention relates to an integrated structure of a power battery module and a liquid cooling system. Background technique:

[0002] With the popularity of electric vehicles, power batteries, as one of the core technologies of electric vehicles, have received more and more attention. As the power device of electric vehicles, the power battery pack needs to have higher output voltage and output power. Therefore, a power battery pack is usually composed of multiple battery modules connected in series and parallel. Among them, the battery module is also composed of multiple single cells connected in series and parallel. At present, with the development of electric vehicles and the needs of people's life and work, power battery packs usually must have high-rate, safe and efficient charging and discharging performance. When the power battery is charged or discharged at a high rate, a large amount of heat will be generated, causing the temperature of t...
