The invention provides a heat storage type heating device for a pure electric vehicle. The device comprises a heat storage module (1), a heat exchange module (2), a medium conveying channel (3), an electric heating module (4) and a control unit (5). The heat storage module (1) comprises a graphite-based heat storage material arranged outside the heat exchange module (2). The medium conveying channel (3) penetrates through the heat exchange module (2) and comprises a section connected with a battery heating pipe. The electric heating module (4) converts part of electric energy into heat energyduring charging, and the converted heat energy is stored in the heat storage module (1) through the heat exchange module (2). And the control unit (5) controls the heat storage type heating device tooperate in a heat supplementing mode, an in-vehicle heating mode and a battery heating mode. According to the invention, the electric quantity of the battery is not needed for heating, and the batterycan be prevented from running at low temperature, so the service life of the battery is prolonged, and the endurance mileage of the pure electric vehicle is increased.
本发明提供了一种用于纯电动汽车的储热式供暖装置,其包括储热模块(1)、换热模块(2)、介质传输通道(3)、电加热模块(4)和控制单元(5)。储热模块(1)包括设置在换热模块(2)外部的石墨基储热材料。介质传输通道(3)穿过换热模块(2),并且包括与电池加热管连接的部段。电加热模块(4)在充电时将一部分电能转化为热能,所转化的热能通过换热模块(2)储存在储热模块(1)中。控制单元(5)控制储热式供暖装置在热量补充模式、车内供暖模式及电池升温模式下运行。根据本发明,不需要使用电池的电量进行供暖,且能避免电池在低温下运行,由此提高了电池寿命和纯电动汽车的续航里程。
