Rhombus Energy Solutions, builders of high-power DC fast chargers for the medium- and heavy-duty electric vehicle (EV) market, will be displaying its new RES-D3-CS20 DC fast charger (D3) at this year’s Government Fleet Expo & Conference (GFX).

While most of today’s DC fast chargers that support remote dispensers have a 1:1 relationship  between the dispenser and the power control system (PCS), the D3 is made up of multiple dispensers that share a PCS. For EV fleets, having multiple dispensers that share a PCS significantly reduces overall system costs, which allows customers to maximize their EV investments. 

“We believe that the D3 switching dispenser will accelerate the deployment of electric medium- and heavy-duty vehicles by significantly reducing EVSE cost per port as well as overall  installation costs,” Rick Sander, CEO of Rhombus Energy Solutions, said in a statement.

To build the charger, Rhombus consulted with numerous medium- and heavy-duty EV fleet operators and OEMs. 

GFX will be held November 15-17 at the Orange County Convention Center in Orlando.
