BATTERY PACK AND DEVICE

An embodiment of the present application provides a battery pack and a device. The battery pack includes a battery module, a heat exchange member, a flow guide piece and a heat-conducting connecting piece. The battery module includes a plurality of batteries. Each battery is provided with an explosion-proof valve. The heat exchange member includes a heat exchange plate. The heat exchange plate is connected to the plurality of batteries through the heat-conducting connecting piece, and the heat exchange plate at least partially covers each explosion-proof valve. The flow guide piece is arranged between the plurality of batteries and the heat exchange plate, the flow guide piece is provided with a positioning hole penetrating in a height direction of the battery pack, and the positioning hole exposes the corresponding explosion-proof valve. The flow guide piece separates the corresponding explosion-proof valve from the heat-conducting connecting piece.
