Abstract: A control method for a thermal management system comprising receiving a battery heating signal at the thermal management system including at least one heat exchange branch configured to exchange heat with a battery, and entering, by the thermal management system, a preheating mode. A temperature of a heat exchange medium at an outlet end of the at least one heat exchange branch is greater than or equal to a first threshold T1.

Abstract: Disclosed are a thermal management system, a control method therefor, and a vehicle. The thermal management system includes a battery subsystem. The battery subsystem includes a plurality of heat exchange branches disposed in parallel. The heat exchange branches are configured to exchange heat with a battery. The plurality of heat exchange branches disposed in parallel include a pressure regulation sub-branch and a heat exchange sub-branch. The control method includes: obtaining a battery heating signal; and the thermal management system enters a preheating mode, where in the preheating mode, a total flow rate Q1 of the pressure regulation sub-branch is substantially greater than a total flow rate Q2 of the heat exchange sub-branch.
