Abstract: Disclosed are a thermal management system and a new energy vehicle. The new energy vehicle includes an electric motor and a thermal management system. The thermal management system includes a refrigeration cycle system, a flow path pump, a first thermal management object, a second thermal management object, and a plurality of three-way valves. The refrigeration cycle system and the flow path pump are separately connected to the plurality of three-way valves. The refrigeration cycle system and the flow path pump are connected to the first thermal management object and the second thermal management object through the plurality of three-way valves respectively. The plurality of three-way valves are separately controlled, to form a first coolant circulation loop and a second coolant circulation loop that are independent of each other, and separately control temperatures of the first thermal management object and the second thermal management object.

Abstract: Embodiments of this application disclose a vehicle thermal management system and method. The system includes a refrigeration cycle system, a coolant cycle system, and a control device, where the coolant cycle system includes a coolant cycle frontend radiator, a power assembly heat dissipation system, a battery pack heat dissipation system, a primary path water pump, a bypass water pump, and a valve bank system. In the system, the refrigeration cycle system is connected to the primary path water pump. Furthermore, in the system, the power assembly heat dissipation system and the battery pack heat dissipation system share the refrigeration cycle system and the coolant cycle frontend radiator by using the primary path water pump, the bypass water pump, and a combination of the valve bank system.
