The invention discloses a vehicle heat exchange system, a control method and device and a storage medium. The vehicle heat exchange system comprises an electric drive system, a battery system and a four-way valve. The four-way valve is connected with the electric drive system and the battery system. When the temperature difference between the temperature of the electric drive system and the temperature of the battery system reaches a preset condition, the four-way valve conducts a loop between the electric drive system and the battery system; at the moment, when the temperature of the electric drive system is larger than that of the battery system, the electric drive system conveys heat to the battery system, and when the temperature of the battery system is larger than that of the electric drive system, the battery system conveys heat to the electric drive system. The four-way valve is additionally arranged between the electric drive system and the battery system, the two systems are independent of each other or combined into a large circulation loop through the on-off state of the four-way valve, and the situation that when a vehicle is cooled, energy is consumed for cooling, and heat is completely released into the environment is avoided; heat transfer is achieved by combining the heat requirements of the battery system and the electric drive system, and the utilization rate of vehicle energy is increased.

    本发明公开了一种车辆热交换系统、控制方法、装置及存储介质。车辆热交换系统包括电驱系统、电池系统和四通阀;四通阀分别与电驱系统和电池系统连接;四通阀在电驱系统温度与电池系统温度的温差达到预设条件时,导通电驱系统与电池系统之间的回路;此时,在电驱系统温度大于电池系统温度时电驱系统将热量输送至电池系统,在电池系统温度大于电驱系统温度时电池系统将热量输送至电驱系统。本发明在电驱系统与电池系统之间增加四通阀,通过四通阀的开关状态使两系统各自独立或合并成大循环回路,避免了车辆在进行冷却时消耗能量降温使热量完全释放到环境中,实现了通过结合电池系统与电驱系统的热需求进行热量转移,提高了对车辆能量的利用率。
