Ideal Power Inc (NASDAQ:IPWR) said it is collaborating with a fourth global Tier 1 automotive supplier to explore the use of its patented B-TRAN semiconductor technology as a replacement for electromechanical contactors in electric and hybrid vehicles.
The new engagement adds to Ideal Power's previously announced collaborations with three other Tier 1 suppliers and three major global automakers, including Stellantis.
“It's exciting to witness the heightened levels of customer engagement and collaboration for solid-state EV contactors,” said Dan Brdar, CEO of Ideal Power in a statement.
“B-TRAN-enabled solid-state EV contactors are generating strong interest from global automotive OEMs and their Tier 1 suppliers due to the ultra-low conduction losses and inherent bidirectionality of our B-TRAN technology.”
Contactors are critical safety devices in EVs that disconnect the battery from subsystems during a crash, fault, or shutdown. While traditional contactors use electromechanical switches, automotive manufacturers are increasingly considering solid-state alternatives for faster operation, improved safety, and enhanced diagnostics.
Ideal Power says its B-TRAN-enabled contactors switch faster, eliminate arcing, and are more reliable than traditional solutions. The technology also reduces the number of switches needed by half, offers programmable current limits, and delivers lower energy losses at a lower cost than silicon carbide-based contactors.
The company said it expects solid-state contactors to surpass electromechanical contactors in the EV market within the next five years.
Austin, Texas-based Ideal Power develops semiconductor power switches for a variety of industrial and transportation applications.
