The invention discloses a thermal management system and a control method thereof, a vehicle, a storage medium and a storage device. The heat management system comprises a battery subsystem, the battery subsystem comprises a plurality of heat exchange branches arranged in parallel, the heat exchange branches are used for exchanging heat with batteries, the plurality of heat exchange branches arranged in parallel comprise a pressure regulation sub-branch and a heat exchange sub-branch, and the control method comprises the steps that a battery heating signal is obtained; and the heat management system enters a preheating mode, and in the preheating mode, the total flow Q1 of the pressure regulation sub-branch is larger than the total flow Q2 of the heat exchange sub-branch. The total flow Q1 of the pressure adjusting sub-branch is set to be larger than the total flow Q2 of the heat exchange sub-branch, and the heat exchange medium at the outlet end is controlled to be kept in a certain temperature state, so that the outlet pressure of the compressor can be improved, and the compressor is prevented from exceeding the operation range and being damaged.
