Why are Audi e-Tron's batteries cooled and heated?

I've heard that Audi e-Tron's batteries have both a cooling and heating system, but I'm not sure why. Could you explain the purpose of this feature and how it works?

The cooling system of e-Tron's batteries helps dissipate heat generated during charging and discharging, which can affect performance and decrease the battery's lifespan if not managed effectively. The heating system, on the other hand, ensures the batteries can operate in cold temperatures without impacting their ability to hold and deliver charge.

The cooling and heating systems for e-Tron's batteries serve the dual purpose of ensuring optimal performance and increasing longevity. By maintaining a consistent temperature, the batteries are able to operate at their best and avoid potential damage.

To minimize potential risks and maximize efficiency, it's standard practice for electric vehicles like Audi e-Tron to have cooling and heating systems for their batteries. This way, the batteries can operate within a safe temperature range and provide the expected range and power without any issues.
