The function of the radiator in an electric car has a function similar to that of a combustion engine car.
The radiator functions as a battery cooling system and an electric car inverter.
The existence of a radiator in an electric car with a lithium-ion battery is needed based on the character of the battery itself.
Lithium-ion has a fairly high heat when compared to other types of batteries. Other types of batteries such as lithium-fero or nickel are not hot enough, they can be cooled with air.
Lithium-ion batteries need additional cooling from liquids such as coolant. Lithium-ion batteries have high-drain properties of small size and capacity.
That way the heat generated from the electricity generated is also high.
Lithium-ion batteries also have an absorption of electric current with a large voltage.
In the process of charging the battery, heat from the high voltage current is also absorbed by the battery.
For this reason, the battery needs extra cooling in the form of a liquid that has a high boiling level.
This liquid will flow in the cavity of the battery module to absorb excess heat from the battery so that it is more stable and maintains battery life.
