OmniOn Power, the former US ABB Power Conversion business, has moved into the EV charger market with a modular 30kW rectifier.
The EV100H3NK and EV101H3N1K AC-DC rectifiers from Omnion have efficiencies of up to 96% and integrate CAN automotive communication protocols. Up to 12 rectifiers can be used in parallel in a 19in rack for fast charging 360kW systems.
For easier maintenance, the rectifier modules feature plug-and-play connectivity, allowing for units to be quickly swapped out when servicing to minimize down time. Remote firmware download supports field upgrades.
Measuring 13.23 inches wide, 3.3 inches high and 17.25 inches deep for 19in rack mounting, the EV100H3NK and EV101H3N1K rectifiers have a 480V three-phase input, as well as 30kW DC fast-charging-compatible output with an adjustable output range of 50-1,000 volts DC (VDC) that is settable by the host charger.
The EV101H3N1K adds a discrete emergency power off circuit for added safety. This functionality enables the rectifier to comply with local or regional jurisdictions that require an electromechanical energy disconnect for rapid shut-down in case of emergency.
The US ABB Power Conversion division in Plano, Texas, was acquired by Taiwanese US-based AcBel Polytech. It has DC Power, Board-Mounted Power, Front-End Power and Life-Cycle Services with manufacturing facilities located in Mexico, China, and India
“While this may be our first product specifically designed for EV charging, we have an extensive history of working with customers to design and develop innovative power solutions for their critical infrastructure, such as the latest wireless architectures and high-performance data centres,” said Gopal Mitra, industrial segment leader for OmniOn Power.
“This inaugural entry into the EV market allows us to apply our deep domain expertise into a growing industry, offering reliability, leadership and guidance to customers looking to build their next fast DC-powered EV charger.”
“Two of the commonly mentioned challenges to widespread EV adoption are the time required for charging and the uptime, or availability, of charging infrastructure. Consumers want to know that a fast charger is going to be available and fast when they drive up to it. Using highly reliable, high-capacity power supplies as the building blocks for next-generation EV chargers will help to address these issues,” said Mitra. “Our history of maintaining and servicing DC fast chargers as well as similar critical DC equipment helps us to anticipate power challenges the industry may face and engineer solutions that help improve uptime and performance.”
