The invention discloses an electric automobile direct current charging and heating system and a control method thereof. The electric automobile direct current charging and heating system comprises a power battery, a direct current charging pile, a battery management module, a water heating PTC, a high-voltage power distribution unit, a whole automobile control unit, a DCDC module and an air conditioner controller. The battery management module sends the temperature and electric quantity signals of the power battery to the whole vehicle control unit through a CAN bus; a charging request instruction sent by the whole vehicle control unit is sent to the direct current charging pile through the charging CAN bus; the water heating PTC executes power battery heating and feeds back a heating state; the whole vehicle control unit is used for completing high-voltage power-on preparation during charging, judging whether the current signal state of the electric vehicle meets the direct-current charging condition or not and sending a heating power signal to the air conditioner controller according to the temperature of the power battery.

    本发明公开了一种电动汽车直流充电加热系统及其控制方法,包括动力电池、直流充电桩、电池管理模块、水暖PTC、高压配电单元、整车控制单元、DCDC模块、空调控制器;电池管理模块将动力电池的温度及电量信号通过CAN总线发送至整车控制单元;并将整车控制单元发送的充电请求指令通过充电CAN总线发送至直流充电桩;水暖PTC执行动力电池加热并反馈加热状态;整车控制单元用于完成充电时高压上电准备,判断电动汽车当前信号状态是否满足直流充电条件,并根据动力电池温度向空调控制器发送加热功率信号。
