Rhombus Energy Solutions to Leverage Wolfspeed’s Silicon Carbide Devices for Faster EV Charging Infrastructure

Rhombus Energy Solutions, a leader in electric vehicle (EV) charging and
power conversion technology, today announced that Wolfspeed, Inc., (NYSE:
WOLF), the global leader in Silicon Carbide technology, will supply its
EV2flexTM line of charging infrastructure products with Silicon Carbide
MOSFETs, which will offer the products greater efficiency, higher power
density and faster charging times.

Rhombus’ EV2flexTM 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 Silicon
Carbide 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 Silicon Carbide 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 Silicon Carbide solutions will help accelerate that transformation,”
said Jay Cameron, senior vice president and general manager of Wolfspeed
Power. “Silicon Carbide 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 Silicon Carbide, 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 Silicon Carbide provider for Rhombus due to its
unmatched, 30+ year history and expertise working with Silicon Carbide power
devices. Wolfspeed’s 1200V Silicon Carbide MOSFETs will power Rhombus’
EV2flex-120TM 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 EV2flexTM portfolio; the EV2flex-120TM dual
channel will be on display at the 2022 Advanced Clean Transportation (ACT)
Expo <https://www.actexpo.com/>  in Long Beach, CA.
