The most common thermal management challenges for EV batteries are leaks, corrosion, clogging, the climate, and aging. As you will see, liquid cooling systems present challenges that are inexistent for air cooling systems. Leaks can only occur in liquid cooling systems, whose pipe connections have risks of leaks as the battery ages.
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.
Too cold batteries may exhibit reduced power output and capacity, while excessively high temperatures can decrease energy storage capacity and power delivery. An efficient cooling system ensures consistent performance, particularly during demanding tasks like rapid acceleration or steep hill climbing.
Thermal shock can occur if the coolant temperature is significantly lower than the battery, potentially causing damage. Liquid cooling system components can consume significant power, reducing overall efficiency while adding weight and size to the battery.
Liquid cooling system components can consume significant power, reducing overall efficiency while adding weight and size to the battery. Coolant compatibility with battery chemistry and materials can vary, potentially limiting use in certain batteries.
