Abstract: Charging and discharging an energy storage device (ESD) generates heat and may prevent its temperature from dropping to unsafe levels. By monitoring and managing the charge and discharge of an ESD with respect to the periods of time in which demand charges are determined, the heating will have minimal adverse effect on demand charges.

Precharging the ESD while heating or preheating the ESD by charging and discharging can prevent new maximum demand levels from appearing and thereby limit increases in demand charges.
