BATTERY PACK AND ELECTRIC DEVICE

A battery pack (100) includes a housing assembly (10), a cell assembly (20), a first circuit board (30), a support (40), and a thermally conductive member (50). The cell assembly (20) is accommodated in the housing assembly (10). The cell assembly (20) includes a plurality of cells (21). Each cell (21) includes a cell housing (211), an electrode assembly (212) disposed in the cell housing (211), and an electrode terminal (213) connected to the electrode assembly (212) and extending out of the cell housing (211). The electrode terminal (213) runs through the first circuit board (30) and is connected to a side of the first circuit board (30) facing away from the cell housing (211). The support (40) is connected to the first circuit board (30), where the first circuit board (30) is disposed between the cell housing (211) and the support (40). The support (40) is provided with a first opening (40a), and the thermally conductive member (50) is disposed in the first opening (40a). The thermally conductive member (50) is connected to at least some of electrode terminals (213).
