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.
