The invention discloses a heating device and a heating method for an electric vehicle. The device includes: a floor heat conducting plate, a floor cooling water pipe, a three-way valve, a first temperature sensor and a vehicle controller; wherein the floor heat conducting plate is installed Under the electric car seat; the floor cooling water pipe is installed in the floor heat conducting plate; the first interface of the three-way valve is connected with the external drive system cooling circulation water pipe, and the second of the three-way valve The interface is connected with the external expansion tank, and the third port of the three-way valve is connected with the inlet of the floor cooling water pipeline; the first temperature sensor is arranged on the first interface of the three-way valve and the drive Between the system cooling circulation water pipes; the vehicle controller is used to control the flow direction of the coolant. The invention solves the problem of low cruising range of the electric vehicle in winter by effectively utilizing the waste heat of the motor to heat the passenger compartment.
Description
technical field [0001] The invention relates to the technical field of pure electric vehicle heating, in particular to an electric vehicle heating device and a heating method. Background technique [0002] At present, the thermal management system of new energy pure electric vehicles generally adopts three independent water cycles according to the different temperature requirements of different components and the needs of the passenger compartment, including the cooling water cycle of the drive system, the cooling / heating water cycle of the battery pack, and the cooling / heating of the passenger compartment. water cycle, such as figure 1 shown. [0003] The cooling cycle of the drive system is similar to the engine cooling cycle of traditional models. The DC-DC converter, on-board charger, motor controller, and drive motor are cooled through the cooling water tank (radiator) and cooling electronic fan. [0004] The battery pack is more sensitive to the ambient temperature, ...
