The embodiment of the invention discloses a thermal management system, a control method thereof and an electric vehicle. The thermal management system is configured in the electric vehicle and comprises a first cooling liquid loop, a second cooling liquid loop and a heating, ventilating and cooling subsystem, the first cooling liquid loop is connected with the electric drive module in a heat exchange mode and comprises an adjustable three-way valve and an adjustable four-way valve. The second cooling liquid loop is connected with the energy storage module in a heat exchange mode and comprises a four-way valve and a cooling device. The heating, ventilating and cooling subsystem is connected with the first cooling liquid loop in a heat exchange mode, and the heating, ventilating and cooling subsystem comprises a cooling device. According to the technical scheme, the energy consumption of the heat management system is reduced, the heating capacity of the heat management system under the low-temperature condition is improved, the after-sale automatic filling mode of the cooling liquid is simplified, the overall structure and the control mode of the heat management system are simplified, and therefore the system cost is reduced.
