The present application provides a heatable battery pack, a heatable battery system and a vehicle having thereof. The heatable battery pack includes a battery, a first switch module, and a heater that are connected in series to form a heating loop. The first switch module turns on the heating loop after a drive signal is received. Compared with the related art in which heaters in various battery packs are connected in series to both ends of a drive module in a high-voltage box, so as to perform high-voltage power supply on the heaters by the high-voltage box through a series loop, the present application directly performs low-voltage power supply on respective heaters by batteries in the battery packs, and the high-voltage power supply by the drive module is not required, which significantly improves the safety of power supply.

Heatable battery pack, heatable battery system, and vehicle

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.
