Battery cooling is a crucial aspect of modern electric vehicles (EVs) to maintain performance, extend battery life, and ensure safety. Types: Passive and active air cooling. Working: Uses ambient or forced air to dissipate heat. Fans may be employed for active air cooling. Simple design and lightweight. Cost-effective.
When air is used for cooling of battery modules arranged in series, the middle and rear portion of batteries are at high temperature to the low heat capacity of air. The temperature of the battery pack near the outlet is very high and the temperature distribution is highly non-uniform.
Liquid cooling is the most popular cooling technology. It uses a liquid coolant such as water, a refrigerant, or ethylene glycol to cool the battery. The liquid goes through tubes, cold plates, or other components that surround the cells and carry heat to another location, such as a radiator or a heat exchanger.
Current flow — while charging and discharging, the EV battery produces heat; the higher the current flow, the more heat will be produced. Using a pipe in the liquid battery cooling system is the most effective way of thermal management because it’s better for receiving heat from battery packs.
Battery cooling can be categorized based on the method or technique. Modern battery cooling methods are crucial for maintaining performance and safety in various applications, especially for electric vehicles (EVs), portable electronics, and energy storage systems.
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.
EV batteries can be cooled using air cooling or liquid cooling. Liquid cooling is the method of choice to meet modern cooling requirements. Let’s go over both methods to understand the difference. Air cooling uses air to cool the battery and exists in the passive and active forms.
