A vehicle thermal management system and associated operation includes using a heat pump system, an electric drive system coolant loop and a battery system coolant loop. The heat pump system includes a compressor, a four-way switching valve, an indoor heat exchanger, a first expansion valve, a first one-way valve, an outdoor heat exchanger, a second expansion valve, a second one-way valve, a second check valve, a chiller, and a gas-liquid separator. The electric drive system coolant loop includes a first water pump, a first three-way valve and a radiator. The battery system coolant loop includes a second water pump, a second one-way valve and a second three-way valve. The thermal management system performs efficient cabin heating with heat recovery of the battery system and electric drive system at low temperatures. The vehicle thermal management system can effectively cool the cabin, the battery system, electric drive system at high temperatures.
