本发明涉及一种车辆热管理系统、方法、装置、车辆和存储介质。系统包括:电驱变速器总成和外置油冷器;电驱变速器总成包括变速器油腔、内置换热器和电机油腔,变速器油腔中设有变速器零部件、变速器油温传感器和第一控制阀;内置换热器用于实现变速器油腔和电机油腔的热量传递;第一控制阀连接变速器零部件和内置换热器,用于根据变速器油温传感器测得的变速器油腔的实时油温连通变速器零部件和内置换热器;外置油冷器用于将电机油腔热量传递到电驱变速器总成外。由于变速器和电机不需要共用油腔,在满足变速器油温的前提下,可以通过外置油冷器降低电机油腔中的油温,提高电驱变速器的工作效率,进而提高车辆整体的驱动效率。

    A vehicle thermal management system, method and device, a vehicle and a storage medium. The system comprises an electrically driven transmission assembly (12) and an external oil cooler (13). The electrically driven transmission assembly comprises a transmission oil cavity (10), an internal heat exchanger (5) and an electric motor oil cavity (11), wherein transmission components (4), a transmission oil temperature sensor (1) and a first control valve (21) are arranged in the transmission oil cavity; the internal heat exchanger is configured for realizing heat transfer of the transmission oil cavity and the electric motor oil cavity; and the first control valve is connected to the transmission components and the internal heat exchanger and is configured for connecting the transmission components to the internal heat exchanger according to the real-time oil temperature of the transmission oil cavity measured by the transmission oil temperature sensor. The external oil cooler is configured for transferring heat of the electric motor oil cavity to the outside of the electrically driven transmission assembly. Since a transmission and an electric motor do not need to share an oil cavity, when the oil temperature requirements of the transmission are met, the oil temperature in the electric motor oil cavity can be reduced by means of the external oil cooler, thereby improving the operating efficiency of the electrically driven transmission and thus improving the overall driving efficiency of a vehicle.
