For the preheating study of the battery system at subzero temperature, they found that a larger gradient angle increment was beneficial to improve the temperature uniformity.
In the battery cooling water loop, after the cooling water absorbs the heat from the battery through a cooling plate, it flows through the fin-and-tube radiator to dissipate the heat to the ambient surroundings and then passes through the chiller to undergo cooling to the target temperature. 2.
