The invention relates to the technical field of vehicle thermal management systems, and relates in particular to a vehicle thermal management system, a control method thereof and a new energy vehicle. The vehicle thermal management system comprises a whole integration of a refrigerant branch, a refrigerant loop, a battery coolant branch, a motor coolant branch, a heating branch and a battery liquid cooling plate branch, so that the thermal management system of a whole vehicle is formed. Compared with the prior art, the vehicle thermal management system provided by the embodiment of the invention has the advantages that a structure of the whole thermal management system is simplified to a great extent, the comprehensiveness of functions is ensured, the requirements of heating, refrigeration, cooling and the like of a vehicle are met, and a battery chiller with three inlets and three outlets is combined with nine valves, and the switching of all branches to realize different functions is achieved; the working difficulty is decreased and the workload is greatly simplified in the assembly process before leaving a factory and in the maintenance process after leaving the factory, and the production and maintenance efficiency is remarkably improved.
