Designing a robust and reliable electric vehicle design is an arduous task that requires several considerations from industry experts wherein EV Battery Cooling Systems play a major role in its operation.
Contrary to conventional vehicle design wherein the air is pulled in through the front grille to optimize engine temperature, electric vehicles do not have such an engine design.
Temperature management of batteries serves as a critical factor in operating any electrified vehicle.
Batteries that power EVs generate heat during use, and high temperatures can negatively impact the battery’s performance and lifespan.
Therefore, it is essential to have a reliable and effective cooling system to maintain the battery temperature.
In short, the key topic of discussion is centered around What is EV Battery Cooling Systems all about and some of the notable Top manufacturers.
A to Z about EV Battery Cooling Systems
Presenting one of the crucial factors in determining the lifecycle of an electric vehicle battery, overheating can accelerate the rate of battery degradation in electric vehicles.
Once the electric vehicle starts operation, the battery produces heat that makes the battery work hard and causes its performance to deteriorate over time.
Due to this, charging the battery in shorter cycles becomes common. Direct current fast charging as well as rapid charging of the battery poses a great risk for battery health, as the accelerated electric currents will further create higher temperatures.
To strike a perfect balance in battery life, electric vehicle driveability, and fuel economy, EV Battery Cooling Systems are considered a lifesaver.
Categorizing the most common types of EV Battery Cooling Systems are into two main categories include liquid cooling and air cooling.
Liquid cooling is more efficient than air cooling and is preferred by most EV manufacturers. In a liquid cooling system, a coolant liquid flows through a series of channels or pipes located in the battery pack to transfer the heat away from the cells. The coolant then circulates through a heat exchanger, where the heat is dissipated into the surrounding air or another coolant system.
Air cooling, on the other hand, uses a fan or blower to move air across the battery cells to dissipate the heat. Air cooling is less complex than liquid cooling, but it is less efficient and can be less effective at maintaining the optimal temperature for the battery cells.
In other words, some thermal management systems also use a direct-contact medium like oil or other dielectric liquids that can directly come in contact with the cells. However, this method is generally used in non-consumer EVs, as they are less safe and provide less effective insulation between the cells and the surrounding environment.
