The invention discloses a thermal management device and a thermal management method of a vehicle-mounted lithium battery, and belongs to the technical field of lithium battery thermal management, and the thermal management device comprises a heat pump circulation unit which is arranged at the negative electrode end of a lithium battery stack and is connected with the lithium battery stack so as to realize refrigeration/heating circulation; and the first vacuum heat insulation layer is connected with one end, far away from the lithium battery stack, of the heat pump circulation unit. According to the thermal management device and the thermal management method for the vehicle-mounted lithium battery, the influence of the external environment on the vehicle-mounted lithium battery can be effectively isolated, and the risks that the capacity of the lithium battery is greatly attenuated in a low-temperature environment and thermal runaway spontaneous combustion is generated in a high-temperature environment are reduced.

    本发明公开了一种车载锂电池的热管理装置及热管理方法,属于锂电池热管理技术领域,包括:热泵循环单元,热泵循环单元设置在锂电池堆的负极端,并与锂电池堆连接,以实现制冷/加热循环;第一真空隔热层,第一真空隔热层与热泵循环单元上远离锂电池堆的一端连接。本发明提供的一种车载锂电池的热管理装置及热管理方法能有效隔绝外界环境对车载锂电池的影响,减低了锂电池在低温环境下容量大幅度衰减以及高温环境产生热失控自燃的风险。
