According to the best design practices in the EV industry, the temperature range should be kept below 6 degrees for a vehicle to perform efficiently. Fig 1. Cell Temperature for Case I
What temperature should a battery pack be stored in?
Extreme temperature are not good for battery packs, and extreme heat is the worst. Temperatures in excess of around 80 degrees Fahrenheit will degrade a battery, with temperatures above 100 or 120 degrees Fahrenheit causing rapid damage. For that reason, it’s best to store batteries in a garage that remains relatively cool during the summer.

What temperature should a car battery be kept at?
Taking 20 °C as optimum, the chemical reaction at 10 °C drops to 50% and at freezing point it is as low as 25%. This means that the performance of the battery can be perfect in the summer at 20 °C, while in the winter nothing happens at 0 °C and the battery needs to be replaced. Battery tests help to detect battery failures in advance.
