Method for reducing energy consumption of air conditioner of pure electric vehicle

Abstract

The invention relates to a method for reducing energy consumption of an air conditioner of a pure electric vehicle, by adopting a partial external circulation strategy, an air conditioner controller can comprehensively consider user requirements and the actual environment to select the optimal position of a circulating air door, the influence of external low temperature on the temperature in the vehicle is reduced, the effects of updating air and reducing fogging of a user are met, the temperature in the vehicle can be rapidly increased, and the contradiction between heating comfort and energy consumption in winter is effectively relieved; during heating in winter, if a user selects external circulation air intake in order to reduce fogging or update air in a vehicle, under the influence of low temperature outside the vehicle, the PTC consumes high power to heat the air in the vehicle and cannot enable the air in the vehicle to quickly meet the comfort requirement, a part of external circulation strategy is started at the moment, so that the effects of updating the air and reducing the fogging can be met, and the comfort in the vehicle can be quickly improved, and thus the PTC energy consumption is reduced.

Description

technical field [0001] The invention relates to a method for controlling an electric vehicle, in particular to a method for reducing energy consumption of an air conditioner of a pure electric vehicle. Background technique [0002] Under the pressure of energy and environmental protection, pure electric vehicles are gradually accepted and loved by everyone. For pure electric vehicles, the main source of power is the battery pack rather than the fuel engine. Therefore, the compressor driven by the traditional engine is replaced by an electric compressor for air conditioning and cooling, and the heating of the air conditioner is replaced by electric PTC heating instead of engine waste heat. Electric compressors and PTCs are high-power electrical appliances, which will increase power consumption when used, resulting in reduced battery life of electric vehicles. Therefore, people would rather endure the heat in summer and cold in winter than turn on the car's air conditioner. H...
