The invention provides a rotating speed control method and device of an electric compressor and a vehicle. The rotating speed control method comprises the steps that the refrigeration requirement of the vehicle is obtained; if the refrigeration requirements comprise the battery refrigeration requirement and the passenger cabin refrigeration requirement at the same time, whether target parameters meet corresponding preset conditions or not is determined; if the target parameters meet the corresponding preset conditions, the refrigeration operation rotating speed of an electric compressor corresponding to battery refrigeration is determined based on the current battery refrigeration demand power, the battery actual water inlet temperature and the battery target cooling liquid temperature; and if the target parameters do not meet the corresponding preset conditions, the electric compressor refrigeration operation rotating speed corresponding to passenger cabin refrigeration is determined based on the current passenger cabin refrigeration demand power, the actual evaporator temperature and the target evaporator temperature. By adopting the technical scheme provided by the invention, the safety requirement of the battery is considered while the comfort of the passenger cabin is fully considered, the energy consumption utilization efficiency is effectively improved, and the comfort of the passenger cabin is improved.
