BATTERY PACK HEATING APPARATUS, HEAT STORAGE APPARATUS AND ELECTRIC CAR

A battery pack heating device, a heat storage device, and an electric car are provided, and may be applied to electric cars. The battery pack heating device includes a battery pack system and a heating system, and the battery pack system is configured to heat a battery pack. The heating system includes at least one heat generating element and a first heat storage apparatus. A reversing valve is disposed between the battery pack system and the heating system, and the reversing valve is configured to control connection and disconnection between the battery pack system and the heating system. In a disconnected state, heat generated by the heat generating element may be stored in the first heat storage apparatus. In a connected state, the heat stored in the first heat storage apparatus can be used to heat the battery pack. In this way, waste heat generated by the heat generating element is used to heat the battery pack, thereby providing an environment-friendly and energy-saving battery pack heating solution.
