Abstract

A method and apparatus for actively cooling the battery pack of an electric vehicle after the vehicle has been turned off, thereby limiting the adverse effects of temperature on battery life, are provided. Different battery pack cooling techniques are provided, thus allowing the cooling technique used in a particular instance to be selected not only based on the thermal needs of the battery pack, but also on the thermal capacity and energy requirements of the selected approach.
