The heat dissipation blades 19 rotate to blow air toward the nickel-metal hydride battery body 7 to cool it. Then, the hot air is discharged to the outside of the base cabinet 1 through the heat dissipation holes 20, thereby avoiding the nickel-metal hydride battery body 7 from overheating and fire, and improving the safety performance of the battery module.

[0019] refer to Figure 1The wiring group includes DC / DC terminals 22, DC / AC terminals 23, reserved DC / AC terminals 24, reserved hydrogen storage terminals 25, 24V power distribution terminals 26, 24V power aviation plug 38 and external CAN aviation plug 39.
