Rhombus launches new bidirectional charging solution for medium- and heavy-duty EV fleets

Rhombus Energy Solutions has launched a new bidirectional “EV charging dispenser.” The RES-D2-CS20 has been certified by Underwriters Laboratory (UL) and the CSA Group for use in medium- and heavy-duty fleet applications. The company calls it a perfect match for the Rhombus 60 kW and 125 kW Power Conditioning Systems.

Rhombus’s bidirectional charger enables Vehicle-to-Grid (V2G) functionality, which allows fleet operators to return energy to the grid during peak demand hours or to be use it to power buildings in a behind-the-meter scenario.

Rhombus has been building high-power inverters to enable behind-the-meter energy storage for renewable energy systems for several years, and has applied that expertise to the design of its latest-generation bidirectional EV charging systems, which are designed specifically for fleet operators.

Electric utility San Diego Gas and Electric has added Rhombus’s chargers to its approved equipment list.

The company’s energy management system controller and software is embedded in its EV charging systems and smart inverters. Rhombus has built hundreds of V2G-capable chargers and bidirectional smart inverters for various sizes and classes of EVs.
