Radiator grilles are a common sight on many makes of cars. You might be aware that this automotive feature is essential for cars to ensure their internal combustion engines (ICE) gets a fresh air supply to stop them from overheating. However, you might also have seen them on electric vehicles (EVs) and wondered why they have them. While it’s true that a car radiator grille can enhance the appeal of an EV, this key component is also performing an important function. Read on to discover why a grille radiator is crucial for electric cars.
Why Radiator Grilles Are Vital For EVs
Unlike ICE vehicles, EVs have no engine generating heat under the bonnet. Instead, they are propelled by electric-powered motors and to run, they use high voltage rechargeable batteries. While no internal combustion is required for an EV to operate, the electric batteries does need a cooling system to ensure they don’t become overheated. Without a radiator grille, car batteries can receive no air to cool them, which can lead to serious issues and expensive repairs.
Why Do Electric Batteries Become Heated?
When they are charging and discharging, EV batteries heat up. The faster the discharge rate, the more heat is generated. The problem is caused by how batteries function. EV batteries depend on the difference in potentials in between their positive and their negative ends. This difference decides the voltage of the battery.When the EV battery heats, the electrons become excited and move around inside. As a result, the voltage difference drops, and the batteries no longer work correctly.
Understanding Optimum Battery Temperatures
The temperature of an EV battery pack should stay between 20˚ to 40˚C and the temperature of every battery cell should remain the same. If not, the cells will discharge and charge at different speeds. As a result, the efficiency of the EV battery pack will decrease.Excessive heat can also result in reduced range for drivers. Batteries operate best at around 21˚. For this reason, automakers recommend that EVs should always be parked in the shade to help extend a battery’s potential range and lifespan. In extreme cases, overheated EV batteries can cause a fire.To ensure battery packs stay at optimum temperature, an onboard cooling system is essential for most models of EV and a radiator grille to supply optimum ventilation.
