The EV air conditioning compressor not only provide the cooling and heating needs for passenger requirement,but also provide the cooling and heating for the battery.The ICE compressor speed follow with engine speed,normal speed is 840～3600rpm.The EV compressor load requirement decide the speed,normal speed is 800～8000rpm.The idle EV compressor noise is very obvious than ICE without engine mask.It is necessary to optimize the natural frequency of the bracket,the compressor rigid body mode,the cavity mode in the vehicle and the steering wheel mode,avoid to resonate and solve the noise and vibration problems in the vehicle.
