Market analysis of electric air-conditioning compressors for new energy vehicles

What is the electric air-conditioning compressor in the whole market? The electric compressor is powered by a battery, and the controller controls the motor speed, thereby controlling the cooling capacity and adjusting the temperature. The scroll compressor's high efficiency and high speed endurance determine that it is suitable for use with high-speed motors, and the electric control unit adjusts the speed of the motor to improve the energy efficiency of the air conditioning system. It is more suitable for use in electric vehicles and has a higher individual value.

What is the electric air-conditioning compressor in the whole market?

air-conditioning compressors

 

Electric air-conditioning compressors are divided into two categories according to the electric drive mode. One is the all-electric compressor, which is driven only by electricity, and is divided into independent and non-independent according to the drive mode; the second is the hybrid drive compressor, which is driven by electricity. The engine and electric motor hybrid drive the compressor, which can switch between the engine drive mode and the electric drive mode to save energy consumption of the car.

 

Both independent electric compressors and non-independent electric compressors can meet the refrigeration performance requirements. In the engine mode, the hybrid drive compressor has a low transmission ratio, resulting in insufficient cooling capacity, which is difficult to meet the comfort requirements of passengers. Therefore, Electric compressors are superior to hybrid drive compressors in cooling capacity. In terms of weight and size, independent electric compressors are better than non-independent electric compressors.

 

At present, stand-alone electric compressors are the main choice for existing new energy vehicles. For an independent all-electric air-conditioning system, the electric vehicle motor directly drives the air-conditioning compressor to cool, so that the air-conditioning compressor can run at the set optimal constant operating speed of the motor, and will not be affected by the operating conditions of the entire vehicle. Generally, the compressor is not driven by a motor through a transmission belt. The coaxial drive scheme is widely adopted at home and abroad. This type of compact structure can adapt to more automobile platforms.
