Title:
BATTERY TEMPERATURE ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/022087
Kind Code:
A1
Abstract:
A battery temperature adjustment device (1) is applied with at least one battery module (M), in which a plurality of chargeable/dischargeable battery cells (C) have been electrically connected in series via conductive members (BB). The battery temperature adjustment device comprises a temperature adjustment member (15, 31) that adjusts the temperature of the battery module. The battery module is configured such that, among the plurality of battery cells, the temperature of a high electric potential cell having a high electric potential is higher than that of a low electric potential cell having a low electric potential, when heat is being generated during charging or discharging. The temperature adjustment member has a plurality of heat transfer sites (HT, 32, 33) set to accommodate the plurality of battery cells, and is configured such that, among the plurality of heat transfer sites, the temperature of the heat transfer site corresponding to the high electric potential cell is lower than the temperature of the heat transfer site corresponding to the low electric potential cell.
