Industry jargon

Battery preconditioning

Battery preconditioning heats or cools an EV battery towards a target temperature before a demanding operating condition such as high-power charging. The vehicle uses its thermal-management system to move the battery closer to the temperature range where it can perform effectively. A cold or very hot battery can accept less charging power than the same battery at a favourable temperature. Preconditioning before a DC charging stop can therefore improve the charging curve. The feature does not increase the battery's capacity. It changes the battery condition so the BMS can permit more suitable power within its limits.
