Description
technical field [0001] The present invention relates to the technical field of battery heat management, in particular to a battery heat management system based on the coupling of liquid cooling and phase change heat storage. Background technique [0002] In recent years, the problems of environmental pollution and energy crisis have become more and more serious, and the popularity of new energy vehicles has become the general trend. As its energy supply, there are strict requirements on the safety performance of lithium-ion power batteries. Under high-rate or high-temperature conditions, thermal runaway is prone to occur, which puts forward requirements for the battery thermal management system. [0003] The traditional thermal management methods are mainly air-cooled heat dissipation system, PCM phase change material heat storage system and liquid-cooled tube heat dissipation system, each of which has its own advantages and disadvantages. For example, air-cooled heat dissi...
