Thermal management control method, system and device

The invention discloses a thermal management control method, system and device, and the method comprises the following steps: if a galvanic pile is started at a low temperature, cooling liquid is controlled to switch a first flow direction and a second flow direction, the flow directions of the first flow direction and the second flow direction in the galvanic pile are opposite, and neither the first flow direction nor the second flow direction flows through a radiator. When the galvanic pile is started at low temperature, the cooling liquid is controlled to switch the first flow direction and the second flow direction, and neither the first flow direction nor the second flow direction flows through the radiator, so that the flow direction of the cooling liquid in the galvanic pile changes continuously, the cooling liquid in the galvanic pile can be distributed more uniformly, and the temperature of the galvanic pile is increased; therefore, rapid and uniform temperature rise of the internal cavity of the gal
