Problems solved by technology

The car air-conditioning system is different. After the air conditioner is turned on, it often takes tens of seconds or even a few minutes for the temperature in the car to reach the set value, and the period for passengers to feel obvious changes in temperature or comfort is longer.
In addition, during the operation of the air-conditioning system, the input power of the air-conditioning system and the corresponding cooling capacity change temporarily, resulting in a longer cycle of temperature changes and even changes in passenger comfort.

Abstract

The invention relates to a control method of an air-conditioning system of an electric vehicle, aiming at providing a self-adaptive control method of the air-conditioning system of the electric vehicle by comprehensively considering the characteristics and the needs of a power supply system, a power system and the air-conditioning system of the electric vehicle. The input power of the air-conditioning system is matched with the consumed power of the power system to optimize the control and operation conditions of the air-conditioning system, so that not only is the power need of the power system met, but also the operation efficiency and the temperature control accuracy of the air-conditioning system are improved, and further the comfort and the energy-efficiency ratio of the air-conditioning system are improved. The self-adaptive control method is also beneficial to improving the continuous mileage of the electric vehicle.

Description

technical field [0001] The invention belongs to the field of electric vehicle manufacturing, and in particular relates to a control method for an air-conditioning system of the electric vehicle. Background technique [0002] The air conditioning system has become the basic configuration of modern automobiles and is an important technology in the field of automobile manufacturing. The air-conditioning system of an ordinary fuel vehicle usually includes a compressor, a condenser, an evaporator, a throttling component and a control system. The air-conditioning compressor is driven by the vehicle engine and electromagnetic clutch, or the air-conditioning compressor is driven by an independent fuel engine. The energy for the operation of the air-conditioning system ultimately comes from the fuel-fired engine, and the control of the air-conditioning system is mainly temperature control. [0003] At present, the air conditioning system of electric vehicles generally also includes ...
