The invention provides an electric commercial vehicle heating system and a control method. The electric commercial vehicle heating system comprises a warm air water heating system, a fuel oil heating system, a battery cooling circulation system, a four-way valve and a controller. The output end of the warm air water heating system is connected with the input end of the fuel oil heating system, the output end of the fuel oil heating system is connected with a first connector of the four-way valve, a second connector of the four-way valve is connected with the input end of the battery cooling circulation system, and a third connector of the four-way valve is connected with the output end of the battery cooling circulation system. The fourth connector is connected with the input end of the warm air water heating system. The signal output end of the controller is connected with the signal input end of the four-way valve, the working mode of the four-way valve is controlled through an output signal of the controller, a circulation loop of the heating system of the electric commercial vehicle is changed, and heating mode switching under different heating requirements is met through one set of fuel oil heating system. The heating cost is reduced while the problems that the battery cannot discharge at low temperature and the air conditioner cannot heat are solved, and the heating power consumption is reduced.

    本发明提出一种电动商用车加热系统及控制方法,包括暖风水加热系统、燃油加热系统、电池冷却循环系统、四通阀和控制器;所述暖风水加热系统的输出端连接燃油加热系统的输入端,所述燃油加热系统的输出端连接四通阀的第一接口,所述四通阀的第二接口连接电池冷却循环系统的输入端,第三接口连接电池冷却循环系统的输出端,第四接口连接暖风水加热系统的输入端;所述控制器的信号输出端连接四通阀的信号输入端,通过控制器的输出信号控制四通阀的工作模式,改变电动商用车加热系统的循环回路,利用一套燃油加热系统满足不同加热需求下的加热模式切换,在解决了电池低温无法放电及空调采暖的问题的同时降低了加热成本,减少了加热电耗。
