The application provides a vehicle thermal management system, a vehicle thermal management method and a vehicle. The vehicle thermal management system comprises: a flow path switching valve; a compressor, an intake port and an exhaust port of the compressor being respectively connected to the flow path switching valve; an in-cabin thermal management flow path, which comprises fluid communication of an in-cabin heat exchanger, a first fan associated to the in-cabin heat exchanger, and a first throttle element connected to the in-cabin heat exchanger; a first end of the in-cabin thermal management flow path being connected to the flow path switching valve; an out-cabin thermal management flow path, which comprises an out-cabin heat exchanger, a second fan associated to the out-cabin heat exchanger, and a second throttle element connected to the out-cabin heat exchanger; a first end of the out-cabin thermal management flow path being connected to the flow path switching valve; and a second end of the out-cabin thermal management flow path being connected to a second end of the in-cabin thermal management flow path; and at least one battery module thermal management flow path, which comprises a cell heat exchanger associated to at least one cell of a battery module, and a third throttle element connected to the cell heat exchanger; a first end of the battery module thermal management flow path being connected to the flow path switching valve; and a second end of the battery module thermal management flow path being connected to the second end of the in-cabin thermal management flow path, the second end of the out-cabin thermal management flow path, and the flow path switching valve, respectively; wherein the flow path switching valve is used for switching the on/off and flow direction of the intake port of the compressor, the exhaust port of the compressor, the in-cabin thermal management flow path, the out-cabin thermal management flow path, and the battery module thermal management flow path. The vehicle thermal management system has high energy efficiency and reliability and is lightweight.
