Phase change material direct contact type battery temperature management system and method

According to the phase change material direct contact type battery temperature management system and method provided by the invention, the phase change material and the thermoelectric element are comprehensively utilized to carry out battery thermal management, and the phase change material and the thermoelectric element are both in direct contact with the single battery. By utilizing an ingenious structural design, a contact surface between the battery module shell and each battery monomer is formed, a supporting force can be provided for the battery monomers while the phase-change material is sealed, the problem of poor heat exchange effect caused by indirect contact type heat management of the phase-change material in the prior art is solved, and the problem of poor heat exchange effect caused by direct contact type heat management of the phase-change material is also solved. And the problems of battery support loss, material leakage, complex structure and the like are easily caused. Meanwhile, the upper s
