Rhombus uses Wolfspeed SiC for Faster EV Charging


Bi-directional charging enables power flow between the power grid and the car

Rhombus Energy Solutions, a company focused on electric vehicle (EV) charging and power conversion, has announced that Wolfspeed will supply its EV2flex line of charging infrastructure products with SiC MOSFETs, which will offer the products greater efficiency, higher power density and faster charging times.

Rhombus’ EV2flex infrastructure includes a family of products that enables fast, bi-directional charging and efficient energy storage. Vehicle-to-grid (V2G) charging supports power flow between the grid and the car, allowing a charged vehicle to become a power source when needed and ultimately enhancing the stability of the power grid.

“Wolfspeed has unequivocally demonstrated the high value of their SiC MOSFETs and we are pleased to partner on advanced technology products,” said Deanne Davidson, senior vice president and general manager of Rhombus Energy Solutions. “As Rhombus continues to be the leading provider for V2G charging systems, Wolfspeed’s SiC MOSFETs are a critical component for Rhombus to meet the demands in the growing DC fast-charging market for EVs.”

“Wolfspeed is excited to work with Rhombus, as we believe bi-directional charging is a game-changing technology for the stability of the power grid and our SiC solutions will help accelerate that transformation,” said Jay Cameron, senior vice president and general manager of Wolfspeed Power. “SiC increases both power system efficiency and power density to create a faster, more reliable transfer of power. Wolfspeed is leading the industry-wide transition from silicon to SiC, which is critical as we look for more efficient and innovative ways to support the power grid, such as bi-directional EV charging.”

Wolfspeed is the preferred SiC provider for Rhombus due to its unmatched, 30+ year history and expertise working with SiC power devices. Wolfspeed’s 1200V SiC MOSFETs will power Rhombus’ EV2flex-120 charging infrastructure. Wolfspeed’s third generation MOSFETs deliver the performance and reliability required to meet a wide variety of industrial, energy and automotive applications.

Rhombus’ latest product in the EV2flex portfolio; the EV2flex-120 dual channel will be on display at the 2022 Advanced Clean Transportation (ACT) Expo in Long Beach, CA.
