Abstract
A battery module includes a plurality of battery cells, a frame receiving the plurality of the battery cells, a fan and a shell. The frame has a front wall and two lateral walls. Two opposite sides of a front surface of the front wall are recessed rearward to form two concave portions. A middle of the front surface of the front wall protrudes outward to form a convex portion between the two concave portions. A plurality of air inlet holes penetrate through the two concave portions. The two lateral walls are recessed inward to form two air outlet holes. The plurality of the air inlet holes are communicated with the two air outlet holes. The fan is disposed to a front of the front wall of the frame. The plurality of the battery cells, the frame and the fan are disposed in the shell.
