The battery must perform perfectly in all weather conditions typical for the climate in which it operates. That’s why we expose the battery to severe frost and extreme heat – to ensure that all battery parts can handle the Nordic climate.
As a rule, a battery discharges fine below freezing but has a harder time charging at very low temperatures. We therefore test that the specially designed heating plates maintain an ideal battery pack temperature. This ensures that the battery also can charge on a cold, sunny winter day.
What’s more, the battery must be able to get rid of heat, as high temperatures can affect the battery cells and shorten their lifetime. That’s why we also test that the silent, convection cooling system is working appropriately.
