A vehicle thermal management system includes a heat pump system, a cabin coolant loop, a low-temperature coolant loop. The heat pump system includes a compressor, a water condenser, an outside heat exchanger, a chiller, an evaporator, a gas-liquid accumulator, a first electronic expansion valve, a second electronic expansion valve, a third electronic expansion valve, and a first four-way valve. The cabin coolant loop includes a first water pump, a coolant heater, a one-way valve, and a heater core. The low-temperature coolant loop includes an electric drive cooling module, a battery pack, a second water pump, a second four-way valve, a three-way valve, a radiator and a hot bottle. A fan and a blower are used to control the front end and cabin airflow. The vehicle thermal management system to provide multiple working modes to assure cabin thermal comfort, control humidity and component temperature with low energy consumption.
