Abstract
Systems and methods of reducing peak energy consumption of a power consumer comprise preprogramming an actual consumption line based on expected power usage, and determining the battery'"'"'s connection time, required departure time, required departure energy and connection energy. A charge rate and a discharge rate are preselected, and a first charge energy level is calculated from the peak energy level less the discharge rate and the charge rate. A connection time of the battery when the battery is connected to the power consumer, a connection energy of the battery at the connection time, a required departure time of the battery, a required departure energy are determined. A power exchange curve is determined during a connection period between the connection time and the required departure time configured to minimize an expected peak energy level.
