Richardson Electronics, Ltd. Receives Patent for Its Ultracapacitor Generator Start Module - ULTRAGEN3000™

LAFOX, Ill., Oct. 02, 2023 (GLOBE NEWSWIRE) -- Richardson Electronics, Ltd. (NASDAQ: RELL), a global provider of engineered solutions for renewable energy, is pleased to announce the issuance of U.S. Patent No. 11,764,002 (the "’002 Patent"). The ’002 Patent is a result of Richardson's innovative technology using ultracapacitors embedded in its ULTRAGEN3000™ generator start module or GSM. The ULTRAGEN3000™ is a compact GSM designed for installation in any orientation, allowing flexible module placement within any generator set housing. The Company's patented technology enables a true drop-in replacement for lead acid batteries in engine start applications without the need to rewire or procure additional components.

Ultracapacitor-based energy storage solutions have significantly enhanced reliability. Ultracapacitors, unlike batteries, provide dependable and consistent energy even in extreme temperatures, providing better reliability for critical applications such as backup generator systems. This new patent adds to the Company's patented energy storage solutions portfolio and enhances growth opportunities within the Green Energy Solutions business segment.

"This patent is another important milestone toward our goal of strengthening our Company's intellectual property portfolio. Our engineering team continues to design and develop unique products that surpass our customers' expectations with cost-savings, reliability, and efficiency," stated Richardson's Greg Peloquin, Executive Vice-President Power and Microwave Technologies and Green Energy Solutions Groups.
