Sustainable Energy Receives Battery/DG Patent

November 06, 2003 by Jeff Shepard

Sustainable Energy Technologies Ltd. (Calgary, Alberta, Canada) announced that the US Patent and Trademark Office has issued a patent covering the company’s innovative approach to the integration of batteries with distributed generation (DG) technologies as part of grid-connected, backup and emergency power systems.

Sustainable Energy’s patented technology enables the battery to be controlled independently of, and in parallel with, the primary power source. This results in reduced cycling of the batteries and higher overall efficiencies. Excessive cycling – charging and discharging – shorten battery life and compromises the integrity of the backup power system.

"Sustainable Energy’s battery interface technology is unique, and an industry first," said Brent Harris, director of technology development. "What this means is that the same inverter platform that is used for a range of grid-interactive applications – solar and small wind power fuel cells, etc. - can be easily and inexpensively upgraded to provide the battery management capability for backup power."
