BATTERY TEMPERATURE CONDITIONING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a battery temperature conditioning device capable of preferentially heating a battery cell arranged at both ends at the time of warming up.

SOLUTION: The battery temperature conditioning device has a housing case and battery cells. The battery cells are arranged in the housing case at prescribed spacings. Passages in which a temperature conditioning medium flows are formed between the battery cells and between the battery cell and the inner wall of the housing case. The direction in which the battery cells are arranged and the direction (flowing direction) in which the temperature conditioning medium flows into the housing case are perpendicular. Further, the temperature conditioning medium flowing part supplies the temperature conditioning medium flowed into the housing case into the passages adjacent to the battery cells at both the ends in the arrangement direction out of a plurality of passages. Thereby, the battery temperature conditioning device warms up the battery cells at both the ends positively and preferentially.
