Ideal Power Collaborates with Fourth Global Tier 1 Automotive Supplier for Solid-State EV Contactors

Strategic Insights -

Ideal Power, developer of the patented B-TRAN bidirectional semiconductor power switch, has announced a collaboration with a fourth global Tier 1 automotive supplier to utilize B-TRAN-enabled contactors as potential replacements for electromechanical contactors in electric vehicle (EV) and hybrid EV applications. This engagement marks another step in the company's expansion into the EV market, following previous collaborations with Stellantis and three other Tier 1 auto suppliers.

Ideal Power's B-TRAN technology provides several benefits over conventional electromechanical contactors, including faster acting, safer, and more reliable operation, programmability, and diagnostic capability. B-TRAN-enabled contactors also offer ultra-low conduction losses and are bidirectional, reducing the number of switches required in a solid-state EV contactor by half.

Key Takeaways:

  • Ideal Power is collaborating with a fourth global Tier 1 automotive supplier to utilize B-TRAN-enabled contactors in EV and hybrid EV applications.
  • The B-TRAN technology offers several benefits over conventional electromechanical contactors, including faster acting, safer, and more reliable operation.
