The invention discloses a control method and device of a compressor and an electric vehicle. The method comprises the steps that the rotating speed of the compressor in a heat management system is monitored; when the rotating speed of the compressor is larger than the preset energy efficiency control critical rotating speed, the rotating speed of the compressor is reduced; and the maximum operation energy efficiency in the compressor rotating speed reducing process is obtained, and operation of the compressor is controlled according to the first target compressor rotating speed corresponding to the maximum operation energy efficiency. According to the control method of the compressor, in the operation process of the heat management system, the temperature of the battery or the passenger compartment can be maintained within the target temperature range, the heat management system can be in the efficient operation state, and the purposes of energy saving and comfort are achieved.

    本申请公开了一种压缩机的控制方法、控制装置及电动汽车,其中方法包括:监测热管理系统中压缩机的转速;当压缩机的转速大于预设的能效控制临界转速时,降低压缩机的转速;获取压缩机转速降低过程中的最大运行能效,并按照最大运行能效所对应的第一目标压缩机转速控制压缩机的运转。本申请提供的压缩机的控制方法可以在热管理系统运行过程中既能使电池或乘客舱的温度维持在目标温度范围内,又可以让热管理系统处于高效的运行状态,达到节能舒适的目的。
