Audi E-Tron Will Use A Heat Pump To Manage Battery Temperature

The Audi E-Tron electric car will be equipped with a heat pump that keeps battery temperatures in their ideal range throughout the seasons, according to TU News.

The news report states that the system will keep the car’s 95 kWh battery pack between 25 and 35 °C, which helps to prevent performance reductions caused by hard acceleration (they get hotter if you push them harder, and that results in reduced power output to the motor).

Audi says the cooling system will address the issue, so that the E-Tron will sustain its performance during aggressive driving periods.

“The thermal cooling system will make it possible to push the pedal on the Audi E-Tron over and over again without any impairment of performance,”, said Anno Mertens, the head of charging infrastructure and electric mobility.

Electric car batteries may be throttled hard during acceleration, resulting in the build-up of heat, which is why this is useful.
