Rhombus Energy Solutions Announces UL and CSA Certifications of Its Remote Charging Dispenser for Fleet Electric Vehicles
Certifications are Applicable for both Unidirectional and Bidirectional Charging Use Cases; Provide ‘Complete Solution’ for Users of Rhombus Fast DC Chargers
SAN DIEGO — JANUARY 21, 2021
Today, Rhombus Energy Solutions is announcing the certification by Underwriters Laboratory (UL) and the Consumer Electronics Testing and Certification Services Group (CSA) of its state-of-the-art RES-D2-CS20 Electric Vehicle (EV) Charging Dispenser. This RES-D2-CS20 EV Dispenser is compatible with Rhombus’s UL Certified 60kW and 125kW Power Conditioning Systems (PCS) for high power EV charging of medium and heavy-duty (M/HD) fleets. The RES-D2-CS20 Dispenser can be used in both unidirectional and bi-directional charging use cases, providing fleet operators for vehicles such as school buses, public transit buses and delivery vehicles with fully certified fast DC chargers that are built specifically for their M/HD EV fleet needs.
The certifications being announced today include UL 2202 (Standard for Electric Vehicle (EV) Charging System Equipment) and UL 2231(Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: Particular Requirements for Protection Devices for Use in Charging Systems), as well as CSA C22.2. These standards define design, safety and testing requirements for all EV charging systems. Combined with the UL 1741-SA certification of Rhombus’ AC to DC PCS units, these certifications allow Rhombus solutions to be used in both unidirectional and bi-directional Vehicle to Grid (V2G) applications, providing a total solution for M/HD EV fleet operators.
“Vehicle electrification allows fleet operators to reduce their operating expenditures by lowering energy and maintenance costs,” said Rick Sander, CEO of Rhombus Energy Solutions. “With bi-directional chargers, fleet operators can integrate renewables and energy storage into their overall solution. To future proof their operations, fleet operators require a highly reliable DC fast-charging infrastructure with bi-directional capability to ensure an optimized solution. Rhombus provides fleets with a complete toolset for their charging needs of today and tomorrow.”
V2G applications, which require bi-directional functionality, provide 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 bi-directional charging with the market-leading reliability of Rhombus’ high-power DC-DC chargers ensures EV OEMs, charging network operators and fleet EV operators that they can install chargers today that will meet tomorrow’s needs. The addition of Rhombus M/HD EV chargers to the San Diego Gas and Electric (SDG&E) approved equipment list is a testament to the capability of Rhombus chargers, and an illustration of the necessity of bi-directional charging functionality going forward.
“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 the certification of our high-reliability dispensers and inverters, fleet operators now have a certified solution for advanced EV charging.”
Rhombus has deployed 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 if needed.
