Based on the position of the liquid cooling system, it can be divided into internal and external cooling. Internal cooling can cool battery from the heat source by incorporating the cooling system into the battery.

This heat is carried from the batteries to the bottom surface of the pack and dissipated by the coolant. Thermal pads are used to remove air gaps from the contacting zone, thereby reducing thermal resistance. Batteries have not been modeled. In place of that, a constant heat flux was applied to the contact area of the cooling plate.
Through the numerical analysis, comparison was carried out to find out the performance of the proposed internal cooling scheme with external cooling scheme. The internal cooling scheme can not only reduce the maximum internal temperature of the battery, but also improve the temperature uniformity between the batteries.
While battery cooling remains essential to prevent overheating, heating elements are also employed to elevate the temperature of the battery in frigid conditions. This proactive heating approach assists in mitigating the adverse temperature effects on the electrochemical reactions, ensuring the battery can still deliver power effectively.
In addition to the choice of fluid, the above concepts also differ in how the cooling plates are attached. A cooling plate can be attached to the battery from above or below in a horizontal position; if high cooling capacity is required, two cooling plates can be used as a sandwich.
