Immersed liquid-cooled battery system that provides higher cooling efficiency and simplifies battery manufacturing compared to conventional liquid cooling methods. The system involves enclosing multiple battery cells in a sealed box and immersing them directly in a cooling medium.
The battery pack heating is also provided by the coolant, while heat sources and heating strategies can widely vary from application (e.g. waste heat recovery from other powertrain systems or direct heating of the battery coolant through PTC heater for example). Coolant cooling is an efficient system for several reasons:
It is the simplest approach to battery cooling. Using conduction through battery and vehicle mounts, as well as natural convection within the battery pack, it transfers the heat generated inside the pack to the environment with no, or limited (e.g. ducting), additional hardware.
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
Xiaoyu Na et al. [61, 62] developed a simplified calculation model for reverse-ventilated battery pack cooling and shown that this technique efficiently reduces the maximum interior battery pack temperature while also reducing the local range of temperatures. However, air cooling cannot effectively manage the temperature in hot weather.

Effective battery cooling measures heat dissipation to prevent overheating, safeguarding the charging rate and the battery from potential overheating issues.
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 cooling strategy is very efficient that can reduce the heat resistance between the heat source and the coolant.
Battery cooling is part of the vehicle's Battery Thermal Management System (BTMS). The BTMS includes the cooling and heating module, as well as the operating strategy, control system and thermal management software.
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.
