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.

    本申请提供了一种电动压缩机的转速控制方法、装置及车辆,所述转速控制方法包括:获取车辆的制冷需求;若所述制冷需求同时包括电池制冷需求和客舱制冷需求时,确定目标参数是否满足相应的预设条件;若目标参数满足相应的预设条件,则基于当前电池制冷需求功率、电池实际入水口温度和电池目标冷却液温度,确定电池制冷对应的电动压缩机制冷运行转速;若目标参数不满足相应的预设条件,则基于当前客舱制冷需求功率、实际蒸发器温度和目标蒸发器温度,确定客舱制冷对应的电动压缩机制冷运行转速。采用本申请提供的技术方案,充分考虑客舱舒适性的同时,兼顾了电池的安全需求,有效提高了能耗利用效率并提升了客舱的舒适性。
