Abstract

An electric load levelling system includes a plurality of individual modules for storing and supplying AC electrical power. Each module is preferably contained within a separate enclosure and includes a plurality of individual electrochemical storage cells for storing DC electrical energy. Each enclosure includes a power conversion mechanism for converting input AC power for storage in the enclosed DC cells, and output DC power from the cells to AC for supply to an input/output line. The system is capable of storing electrical energy during periods of off-peak demand, and outputting such stored energy during periods of peak demand. The individual modules function as an 'AC battery' having an AC input and output, and are adapted for mass production and ease of interchangeability.
