Problems solved by technology

[0003] At present, due to the limitation of the development of electric compressors in China, the control of electric compressors in the vehicle air-conditioning system mainly adopts classification, PWM control and speed regulation, etc., and only performs single control for the working requirements of the air-conditioning system, and the electric compressor does not participate or only Passively participate in the cooling of the battery system
The air-conditioning system and the battery system communicate with the vehicle controller through the CAN bus, which does not form a closed-loop and efficient system control

Abstract

The invention relates to the technical field of new energy automobiles, in particular to a control method and device of a motor compressor of a new energy automobile and a system. Dual objective energy-saving control is carried out on the motor compressor by uniformly managing power battery cooling and air conditioning refrigeration, the rotating speed of the motor compressor is adjusted dynamically the combining a power battery cooling requirement and a passenger compartment temperature reduction requirement, the passenger compartment air conditioning refrigeration effect is improved, intermittent hot wind in the process of the air conditioning refrigeration can be avoided completely, and the comfort level of the passenger compartment is improved; and dual objective adjusting dynamic balances the thermal load of an air conditioning system, high efficiency and energy saving are realized, and the driving mileage of a whole vehicle can be further improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a control method, device and system for an electric compressor of a new energy vehicle. Background technique [0002] With the limitation of air pollution control and national fuel consumption goals, new energy vehicles have attracted more and more attention from the market and enterprises. The new electric air conditioning system and battery cooling requirements are directly related to their power economy. [0003] At present, due to the limitation of the development of electric compressors in China, the control of electric compressors in the vehicle air-conditioning system mainly adopts classification, PWM control and speed regulation, etc., and only performs single control for the working requirements of the air-conditioning system, and the electric compressor does not participate or only Passively participate in the cooling of the battery system. The air-conditio...
