Methods of decreasing peak energy consumption
First Claim
1. A method performed by a computer program for decreasing peak energy consumption of a power consumer comprising:
- preprogramming an actual consumption line based on expected power usage, the actual consumption line having a peak consumption time;
determining a connection period of a selectively connectable battery to a charging station of the power consumer between a connection time and a departure time;
determining an available energy based on a required departure energy and a connection energy;
determining an average expected consumption line over the connection period based on the actual consumption line, the required departure energy, and the connection energy;
determining a charge line and a discharge line based on the average expected consumption line;
determining charging periods and discharging periods based on the charge line, discharge line, and the actual consumption line;
determining a predicted battery capacity across the connection period and an energy transfer deficiency;
adjusting the discharge line based on the energy transfer deficiency, wherein if the predicted battery capacity at the departure time is greater than the required departure energy, and if the predicted battery capacity is between a maximum threshold and a minimum threshold during the discharging periods, adjusting the discharge line equal to the average expected consumption line;
charging the battery with the power consumer during the charging periods; and
discharging the battery to the power consumer during the discharging periods.

Abstract
Methods of reducing peak energy consumption of a power consumer are provided. One such method comprises preprogramming an actual consumption line based on actual power usage, the actual consumption line having peak start time, a peak end time and a peak consumption time; determining a connection period of a battery of a vehicle to a charging station of the power consumer; determining an available energy between the required departure energy of the battery and the connection energy; determining an average expected consumption line that averages the actual power usage over the connection period; and determining a charge/discharge line by adjusting the average expected consumption line based on the available energy and the connection period.
