Document Type and Number:
WIPO Patent Application WO/2020/220867
Kind Code:
A1
Abstract:
A battery pack heating apparatus, a heat storage apparatus and an electric car. The invention is applicable to electric cars. The battery pack heating apparatus comprises a battery pack system and a heat supply system. The battery pack system is used to heat a battery pack. The heat supply system comprises at least one heating element and a first heat storage device. A directional valve is provided between the battery pack system and the heat supply system. The directional valve controls connection and disconnection of the battery pack system and the heat supply system. In a disconnected state, heat generated by the heating element can be stored in the first heat storage device. In a connected state, the heat stored in the first heat storage device can be used to heat a battery pack. The invention employs waste heat generated by a heating element to heat a battery pack, thereby providing an environmentally-friendly and energy-saving solution for heating battery packs.
