Abstract: 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.

Abstract: A thermal management device and a battery pack are provided. The thermal management device applied in a battery pack. The battery pack includes a case and a plurality of cells received in the case. The thermal management device includes: a thermal management loop attached to each cell and at least partially covering a part of a vent of each cell; a heat exchange member communicating with the thermal management loop; and a power component connected between the thermal management loop and the heat exchange member. A heat exchange medium with a fire-extinguishing function is provided within the thermal management loop. The thermal management loop is broken in a condition where at least one cell is subjected to thermal runaway such that the heat exchange medium flows into an explosion-proof port of the at least one cell.
