Abstract

The invention relates to a heating method and system for a hybrid electric vehicle, belonging to the field of new energy vehicles. The method includes: the processing unit detects whether the power battery is working normally; when the processing unit determines that the power battery is not working normally, the engine provides electric energy for the electric heater; when the processing unit determines that the power battery is working normally, the engine and the power battery jointly provide electricity The electric energy of the heater, or the electric energy of the electric heater provided by the engine alone. The invention directly provides electric energy for the electric heater through the engine, which solves the problem in the prior art that when the power battery cannot work normally, the electric heater has no electric energy supply, and the heat energy is only provided by the engine water jacket, and the heating effect is poor; Regardless of whether the power battery can work normally, the electric heater can obtain electric energy and provide hot water for the heater core.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a heating method and system for a hybrid vehicle. Background technique [0002] A hybrid vehicle usually refers to a vehicle with two power sources, an engine and a power battery. Hybrid vehicles can achieve long-distance long-distance driving like traditional vehicles, while saving energy and reducing emissions in the form of hybrid power. It can also achieve short-distance zero emissions in the form of pure electric vehicles, and the heating system of hybrid vehicles is also different from that of traditional vehicles. [0003] In the related art, there is a heating method for hybrid electric vehicles. In this method, the electric heater and the engine water jacket are used to jointly heat the water flow, and then the water flow heats the heater core. After the heater core dissipates heat, the heating is realized. The electric heater is composed of The traction battery supp...
