Patent ID: 8228034

Claim:
A system for storing electrical energy during an off-peak period and distributing the electrical energy during a peak period, wherein the system comprises: an energy storage means comprising at least two sodium-nickel-chloride batteries having a specific energy in the range of about 80 to about 200 Wh/kg, each battery having a corresponding battery management interface and an operating mode; a multiple battery server comprising monitoring control software for monitoring the system and for controlling current flow within the system, the multiple battery server being configured to receive data relating to each battery from each corresponding battery management interface; a first means for directing the electrical energy produced during the off-peak period into the energy storage means comprising at least one charger for converting alternating current into direct current and the multiple battery server controlling the flow of the alternating current into the at least one charger, wherein the direct current is stored in the energy storage means; a second means for directing the electrical energy from the energy storage means during the peak period comprising a power management cabinet for controlling the discharge of the stored electrical energy from the energy storage means, the power management cabinet configured to receive a discharge signal and a stop discharging signal from the monitoring control software.
