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: A heat management system and an electric vehicle. The heat management system may be configured in the electric vehicle. A plurality of heat management requirements are generated under different conditions such as different operating conditions (such as driving and a charging request) of the electric vehicle, a current ambient temperature of the electric vehicle, a temperature of a battery pack, or a heat status (that is, a heat value) of a power assembly. Therefore, the heat management system can select different circulation manners of a coolant for different heat management requirements. The heat management system adjusts opening or closing of each valve port in the multi-path direction control valve assembly to select different circulation manners of the coolant, to reduce energy consumption and costs generated when the heat management system performs heat management on the power assembly and the battery pack.
