The invention discloses an electric vehicle air conditioning heat pump system adopting double bypass valves and an electronic expansion valve. The system comprises a compressor, a first indoor heat exchanger, a second indoor heat exchanger, a gas-liquid separator and an outdoor heat exchanger, wherein the compressor is connected to the outdoor heat exchanger through a first electromagnetic valve,the outdoor heat exchanger is connected to the first indoor heat exchanger through a thermostatic expansion valve with a cut-off function, the first indoor heat exchanger is connected to the compressor through the gas-liquid separator so as to form a refrigerating loop, the compressor is further connected to the second indoor heat exchanger, the second indoor heat exchanger is connected to the outdoor heat exchanger through the electronic expansion valve, and the outdoor heat exchanger is connected to the compressor through a second electromagnetic valve and the gas-liquid separator so as to form a heating loop. According to the electric vehicle air conditioning heat pump system adopting the double bypass valves and the electronic expansion valve, the energy consumption of an air conditioning system of an electric vehicle can be effectively reduced, and the endurance mileage of the vehicle can be guaranteed.
