So does this mean that they dont require cooling at all?
In fact, cooling is absolutely necessary for the batterys function.
The ideal working temperature range of a battery is set between 20 and 45 degrees Celsius.
Lithium-ion batteries heat up both while in use and during charging and discharging at high rates.
Letting the heat build up is dangerous.
It can lead toa thermal runaway, which, in turn, can result in fire or combustion.
How do EVs cool their batteries down?
The heat exchanger can be connected to the vehicles air conditioning system to warm up the cabin.
A cheaper but less efficient method is air cooling.
