Abstract
A battery pack cooling system includes a battery pack case, a cooling fluid passage, a cooling medium passage and a water absorber. The battery pack case houses a battery module. The cooling fluid passage is disposed in a vicinity of the battery module. Cooling fluid for cooling the battery module is to flow through the cooling fluid passage. The cooling medium passage is configured to exchange heat with the cooling fluid. The cooling medium passage is disposed so as to be exposed to a space in the battery pack case. Cooling medium is to flow through the cooling medium passage. The water absorber is made of a water absorbable material. The water absorber is configured to absorb water that is condensed on the cooling medium passage.
