Document Type and Number:
WIPO Patent Application WO/2019/184364
Kind Code:
A1
Abstract:
Disclosed in the present invention is a thermal management assembly for a power battery pack, for use in solving the technical problem in the prior art of adjusting the temperature of a power battery pack by means of a refrigerant medium. The thermal management assembly comprises battery modules; several cells arranged side by side are provided in each battery module; a heat conducting plate is provided adjacent to each cell for heat transfer; an end of the heat conducting plate is provided with a bent and extending heat conducting portion; the heat conducting portion contacts a vapor chamber for heat transfer; a thermoelectric cooler is provided in the battery module, and the thermoelectric cooler comprises two heat conducting surfaces; the inner heat conducting surface contacts the vapor chamber for heat transfer, and the outer heat conducting surface contacts a heat dissipation plate for heat transfer. The present invention can effectively improve the thermal management level of a battery pack, ensure the battery pack to work in an appropriate temperature range, improve the performance of the battery pack, and prolong the service life of the battery, and can also make an energy storage system lighter.
