The invention provides a control method, device and equipment of an electric automobile and a storage medium, and relates to the technical field of temperature control and optimization of heat pump systems, a direct heat pump system and an air conditioning system are arranged in the electric automobile, and the heat pump system comprises an internal condenser and a compressor; when the air conditioning system is in the working mode, the working mode of a heat pump system is obtained, the first temperature of cooling liquid in a battery, the second temperature of an internal condenser and the exhaust pressure of a compressor are monitored in the heat pump mode, and whether a battery heat storage mode is started or not is judged based on the requested air outlet temperature, the first temperature, the second temperature and the exhaust pressure; the opening degree of a battery cooling liquid temperature control valve is adjusted according to the first temperature during entering so as to remove redundant heat in the heat pump system and prevent the system from quitting a heat pump mode due to too high pressure, so that the direct heat pump system can continuously work, the stability of the heat pump system is improved, the actual air outlet temperature of the air conditioning system is kept stable, and the service life of the air conditioning system is prolonged. And the comfort of the passenger compartment is further ensured.

    本申请提供一种电动汽车的控制方法、装置、设备及存储介质,涉及热泵系统的温度控制和优化技术领域,电动汽车内置有直接式热泵系统和空调系统,热泵系统中包含内部冷凝器和压缩机;在空调系统处于工作模式下,获取热泵系统的工作模式,热泵模式时监测电池中冷却液的第一温度、内部冷凝器的第二温度和压缩机的排气压力,基于请求出风温度、第一温度、第二温度和排气压力,判断是否进入电池储热模式,并在进入时根据第一温度调整电池冷却液温度控制阀的开度,以去除热泵系统中的多余热量,防止系统压力过高退出热泵模式,使直接式热泵系统能够持续工作,从而提高热泵系统的稳定性,使得空调系统的实际出风温度维持稳定,进而保证乘员舱的舒适性。
