BATTERY TEMPERATURE REGULATION DEVICE

摘要

The present invention prevents condensed water produced in the evaporator of a temperature control unit from reaching an electrode of a battery module. The battery temperature control device is provided with a battery pack case (1) that houses a temperature control unit (3) and a battery stack (2) as a group of battery modules. In the battery temperature control device, the temperature control unit (3) has: an evaporator (32) that performs heat exchange using the air conditioning unit (107) from the upstream side of the direction of airflow; a blower fan (33) that recirculates the interior air inside the pack case; a PTC heater (34) as a fin member; and a unit duct (35) that supplies air to the battery stack (2).
