Tannas Co. awarded U.S. patent for advanced lubrication testing technology targeting ev reliability and performance

Tannas Co., a global leader in lubrication testing and reliability solutions, has been awarded a new U.S. patent for its innovative wire corrosion test board used in the TANEV WCT® instrument, marking another important step forward in advancing electric vehicle (EV) reliability.

U.S. Patent No. D1,126,020 S covers an innovative test apparatus designed to evaluate the corrosivity of a fluid on conductive metals when exposed simultaneously to electrical, thermal, and chemical stresses. The patent design enables accurate assessment of corrosion performance in both liquid and vapor phases, offering valuable insight into degradation and failure mechanisms that can affect the reliability and durability of modern electrified systems.

As EV technologies evolve, managing corrosion in electrical components has become increasingly critical. Tannas’ innovation directly addresses real-world challenges such as conductive deposits and wire degradation, which can compromise the safety, performance, and lifespan of EV drivetrains and electrical systems.

Unlike traditional methods that measure corrosion after it has occurred, the TANEV WCT® test board (used in the TANEV WCT® instrument) enables users to:

• Predict the onset of copper corrosion,
• Analyze corrosion rates under specific operating conditions,
• Improve material selection to enhance durability, safety, and performance.

“This patent represents a significant milestone for Tannas Co. and reinforces our commitment to innovation in our instrumentation,” said Antonio Di Bartolo, general manager of Tannas Company and the three other consortium companies that make up the Savant Group. “We are focused on developing solutions that address real-world challenges and deliver measurable value to our customers.”

While originally developed for EV applications, the wire corrosion test is also highly relevant for industries that rely on motors, windings, connectors, and complex circuitry, where material reliability is essential.

The patented design strengthens Tannas Co.’s broader portfolio of instrumentation focused on lubricant performance testing and electrification challenges. As industry continues to integrate electrified components into traditionally mechanical systems, demand is increasing for standardized, application-relevant corrosion testing methodologies that better model electrified systems.

Filed on October 3, 2024, the patent reflects Tannas Co.’s continued investment in translating laboratory insight into deployable testing solutions that address emerging reliability concerns across energy, chemical processing, and transportation sectors.

The design patent is valid for 15 years. The Savant Group’s portfolio of over 40 U.S. patents - focused on lubricant performance testing, corrosion evaluation, and precision laboratory instrumentation - has contributed significantly to the development of standardized methodologies widely adopted across the petrochemical and energy sectors.
