US Patent 10424820 Battery module

A battery module includes battery packs. Heat may be efficiently dissipated from the battery packs of the battery module, and heat dissipating efficiency may not vary according to positions of the battery packs; that is, heat may be uniformly dissipated. In addition, leakage of a cooling medium for dissipating heat may be prevented, and permeation of the cooling medium into the battery packs may be prevented.
