Abstract
An apparatus is described including a hybrid power train having an internal combustion engine and an electric motor. The apparatus includes a hybrid power system battery pack that is electrically coupled to the electric motor. The apparatus includes an energy securing device that is thermally coupled to the hybrid power system battery pack. The energy securing device selectively removes thermal energy from the hybrid power system battery pack, and secure removed thermal energy. The energy securing device secures the removed thermal energy by storing the energy in a non-thermal for, or by using the energy to accommodate a present energy requirement.
