[0086] The vehicle thermal management system further comprises a second multi-way valve 64, which comprises a temperature-controlled three-way valve, and the second multi-way valve 64 comprises a fourth interface, a fifth interface and a sixth interface, wherein the fourth interface of the second multi-way valve 64 is connected to the cold storage assembly 3, the fifth interface of the second multi-way valve 64 is connected to the indoor evaporator 7, and the sixth interface of the second multi-way valve 64 is connected to the battery heat exchanger 8.

[0089] When the vehicle thermal management system comprises the compressor 6, the first heat exchanger 22, the cold storage assembly 3 and the indoor evaporator 7, one end of the first heat exchanger 22 is connected to one end of the cold storage assembly 3, the other end of the first heat exchanger 22 is connected to the compressor 6, one end of the indoor evaporator 7 is connected to the compressor 6, and the other end of the indoor evaporator 7 and the other end of the cold storage assembly 3 are both connected to the other end of the compressor 6.

[0090] When the vehicle refrigerator is in a non-working state, the first multi-way valve 61 is adapted to prevent the refrigerant flowing out of the compressor 6 from flowing to the first heat exchanger 22, and the second multi-way valve 64 allows the refrigerant flowing out of the compressor 6 to flow to the cold storage assembly 3 after flowing through the indoor evaporator 7, so that the refrigerant flowing out of the compressor 6 flows to the cold storage assembly 3 after flowing through the indoor evaporator 7 to cool the cold storage medium of the cold storage assembly 3. At this time, the first stop valve 62 is in a closed state to prevent the refrigerant flowing through the cold storage assembly 3 from flowing to the first heat exchanger 22.
