Abstract

The invention discloses a control method, a controller, and a system of a multi-heat-source heating system of an electric automobile and an automobile. The method comprises the following steps: responding to a condition that a battery of the electric automobile meets a first temperature condition, starting a fuel heater, enabling a heating channel to heat a battery compartment of the electric automobile, and according to the heating requirement of a passenger compartment, enabling the electric heater to be turned on or turned off; in response to the fact that the battery of the electric automobile meets the second temperature condition, if the passenger compartment has the heating requirement, controlling the heat supply proportion of the heating channel to the battery compartment and / or the passenger compartment according to the heating requirement of the passenger compartment; and responding to the condition that the battery of the electric automobile meets the third temperature condition, according to the heating requirement of the passenger compartment, opening or closing the fuel oil heater, and enabling the heating channel to supply heat to the passenger compartment. Based on different temperature conditions of the battery and the heating requirement of the passenger compartment, the passenger compartment side comfort and the battery performance requirement can be balanced, the electric quantity consumption of the whole automobile can be reduced, and the endurance mileage is prolonged.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to a control method, a controller, a system and an automobile for a multi-heat source heating system of an electric automobile. Background technique [0002] For new energy vehicles, due to the low charging and discharging efficiency of the battery at low temperature, it is necessary to heat the battery at low temperature. At the same time, in order to improve the comfort of passengers, it is also necessary to heat the passenger compartment. [0003] At present, the mainstream solutions for passenger compartment heating and battery heating of new energy vehicles use separate heat sources to provide heat for the passengers in the passenger compartment and for the batteries in the battery compartment. The heat source control of the passenger compartment and the battery compartment heating do not affect each other, and there is a defect that it consumes more energy, which ...
