BATTERY MODULE AND ELECTRIC DEVICE

A battery module (100) includes a housing assembly, a cell assembly (20), a circuit board (30), and a first connecting member (40). The housing assembly includes a first side wall (11) and a second side wall (12). The first side wall (11) is provided with a first through hole (10a). The second side wall (12) is provided with a second through hole (10b). The cell assembly (20) is accommodated in the housing assembly. The cell assembly (20) includes cells. The cell includes a cell housing (211), an electrode assembly disposed in the cell housing (211), and an electrode terminal (212) connecting to the electrode assembly and led out of the cell housing (211). The circuit board (30) connects to the electrode terminal (212). The first connecting member (40) connects to the circuit board (30). The first connecting member (40) is disposed in the first through hole (10a) and the second through hole (10b). The first connecting member (40) is provided with a first channel (40a). The first channel (40a) communicates with the first through hole (10a) and the second through hole (10b). The first connecting member (40) dissipates heat of the circuit board (30) out of the first through hole (10a) and the second through hole (10b) to an external environment via the first channel (40a), improving heat dissipation for the circuit board (30), thereby lowering temperature of the battery module (100).
