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.
