Patent abstract
Disclosed herein is a cooling system for a battery pack that is usable as a power source of electric vehicles and hybrid-electric vehicles. The cooling system has the effect of effectively dissipating heat generated from battery cells by supplying a refrigerant to the battery cells at a constant flow rate, and of minimizing a temperature difference between the battery cells during a cooling process. This prevents degradation in the performance of the battery cells, and achieves optimal temperature control. Also, the cooling system employs a single refrigerant guide member arranged at a side of the battery pack, resulting in a reduction in the size of an overall battery system.
