SAN DIEGO, Mar. 9, 2021 /PRNewswire-PRWeb/ — Today, Rhombus Energy Solutions is announcing the certification of its bi-directional 125 kilowatt (kW) DC fast charger to the Underwriter Laboratories 1741-SA standard. This latest certification now provides medium and heavy duty (M/HD) EV fleet operators with two Rhombus products to meet their needs – the Rhombus 125kW charger and the previously-certified Rhombus 60kW charger. Since both of these chargers and their associated dispensers are bi-directional certified, they can now be utilized in both Vehicle to Everything (V2X) and unidirectional charging use cases by M/HD EV fleet operators.
UL 1741-SA is UL’s Standard for Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources. This standard defines the design and testing requirements to certify that bi-directional, grid tied, «smart» inverters and electric vehicle (EV) chargers can be safely used to support the distributed generation (DG) grid services and applications. Utilities in the United States and worldwide are increasingly interested in opportunities to cost effectively add energy storage to support increasing levels of intermittent renewable energy sources. This certification builds on Rhombus’ existing UL 1741-SA certification of the Rhombus 60kW high-power charger PCS, as well as the certification of the Company’s EV charging dispensers to UL 2202, 2231, and CSA C22.2 standards.
«With the certification of the Rhombus 125kW bi-directional charger, fleet EV operators now have multiple bi-directional charger choices for their medium-duty and heavy-duty vehicles,» said Rick Sander, CEO of Rhombus Energy Solutions. «Whether the fleets consist of school buses, public transit buses, delivery vehicles, cargo drayage tractors or heavy municipal vehicles such as refuse trucks, the Rhombus 125kW charger provides the ideal opportunity to cut charging time in half. And with its bi-directional capabilities, the 125kW charger can provide vehicle to grid (V2G) capabilities when used with aggregation platforms such as those from Nuvve, Amply, Electriphi and others.»
V2G technology provides a means for EV fleet operators to utilize their vehicles as a source of energy storage, allowing power to be put back onto the grid during peak demand hours, or to be used to power buildings in a «behind the meter» approach. The combination of V2G aggregation platforms and the market-leading reliability of Rhombus’s high-power fast DC chargers provides fleet operators with tools to significantly reduce energy costs by enabling them to put power back on the grid during high rate peak hours, and then recharging during off-peak, lower rate times. The combination also allows fleet operators for vehicles such as school buses to provide emergency power to buildings during power outages.
«We designed our electric vehicle chargers to meet the specific needs of medium and heavy-duty EV fleet operators,» said Joseph Gottlieb, CTO of Rhombus Energy Solutions. «With our 125kW charger, operators can charge their vehicles twice as fast as with a 60kW charger, and the addition of the UL 1741-SA certification for our chargers enables a broader use case encompassing V2G capability.»
Rhombus has fielded hundreds of high-power, bi-directional, high-reliability fleet EV charging systems and inverters for energy storage and PV solar-based microgrid, for customers in a variety of demanding operational environments. Bi-directional charging enables both significant energy cost savings for EV fleet operators and the ability to provide power to critical infrastructure during power emergencies when needed.
