The invention relates to a vehicle thermal management system, method and device, a vehicle and a storage medium. The system comprises an electric drive transmission assembly and an external oil cooler. The electric drive transmission assembly comprises a transmission oil cavity, a built-in heat exchanger and a motor oil cavity. Transmission parts, a transmission oil temperature sensor and a first control valve are arranged in the transmission oil cavity. The built-in heat exchanger is used for realizing heat transfer between the transmission oil cavity and the motor oil cavity; the first control valve is connected with transmission parts and the built-in heat exchanger and used for communicating the transmission parts and the built-in heat exchanger according to the real-time oil temperature, measured by the transmission oil temperature sensor, of a transmission oil cavity. And the external oil cooler is used for transferring heat of the motor oil cavity to the outside of the electrically-driven transmission assembly. Due to the fact that the transmission and the motor do not need to share the oil cavity, on the premise that the oil temperature of the transmission is met, the oil temperature in the motor oil cavity can be reduced through the external oil cooler, the working efficiency of the electric transmission is improved, and the overall driving efficiency of a vehicle is improved.
