Richardson Electronics has announced the issuance of US Patent No. 11,073,130 (the ’130 Patent). The ’130 Patent is a result of Richardson’s solutions for replacing lead-acid batteries in wind turbine pitch systems.

Richardson’s solution is embodied in its ULTRA3000 Pitch Energy Module (PEM). The ULTRA3000 is an ultracapacitor-based plug-and-play replacement for batteries, including General Electric’s (GE) wind turbine pitch systems. The ULTRA3000 PEM is a direct one-for-one replacement for the GE batteries and chargers and can be installed with no modifications to the battery box.

We are very pleased the US Patent Office recognised the innovation of our ULTRA3000 Pitch Energy Module. The Richardson engineering and manufacturing team worked hard on this product to make it a truly plug-and-play product, allowing for easy and efficient installation,” stated Richardson’s Greg Peloquin, Executive Vice-President, Power and Microwave Technologies Group. “We are excited to bring the ULTRA3000 to market and provide a cost-effective, improved solution for replacing lead-acid batteries in wind turbine pitch systems.”

Richardson will be presenting its patented ULTRA3000 PEM at the upcoming Symposium APETT show, held 8th September 2021, in Denmark, and the Cleanpower Expo, held 7th-8th December 2021, at the Salt Palace Convention Center in Salt Lake City, Utah.
