International Classification:

H01M 2/12
H01M 10/50

US Classification:

429 82

Abstract:

A battery module having a first battery cell; a frame member having first and second sides and first, second, third and fourth peripheral walls; and first and second thermally conductive plate members is provided. A plurality of flow channels are formed by the first and second thermally conductive plates. The third peripheral wall has a first outlet that receives the first electrical terminal of the first battery cell therethrough, such that if the first battery cell outputs gases therefrom the first outlet routes the gases from the first battery cell to outside of the frame member such that the gases are isolated from the air flowing through the plurality of flow channels.
