LEM’s new UL-certified bidirectional DC meter for quick EV chargers
The general public charging trade is shifting in the direction of per-kilowatt-hour (versus time-based) billing, and producers will more and more be required to include licensed DC meters into their charging stations.
To fulfill this want, electrical measurement specialist LEM has launched the DCBM, a UL-listed bidirectional DC meter for quick EV chargers.
The DCBM “will allow makers of EV charging stations to speed up their certification for DC metering necessities following Licensed Take a look at and Analysis Skilled/Nationwide Kind Analysis Program (CTEP/NTEP) certification,” says LEM. “The DCBM will simplify the method of the producers having to qualify their very own charging stations for UL certification and, for further peace of thoughts, will bear a recent audit each quarter.”
The brand new meter is able to monitoring present, voltage, temperature and power utilization, and has been designed with information safety and adaptability in thoughts. The DCBM 400/600 complies with the requirements UL 61010 and UL 810 within the FTRZ class for EV functions. To attain this certification, the meter needed to go strengthened insulation assessments, temperature testing of all its parts and sub-assemblies, testing for cover towards electrical shock, sturdiness of markings assessments, gear temperature restrict assessments and resistance to warmth/fireplace danger assessments.
The DCBM is designed for DC chargers from 25 kW to 400 kW, and integrates the signed billing information units in accordance with the Open Cost Metering Format (OCMF) protocol. It may be retrofitted to current charging stations, and has a moveable measuring factor to be used with any sort of charging station structure. It’s correct in temperatures of -40° to 185 °F, and has an IP20-rated casing.
Different options embrace Ethernet help and bidirectional power metering, which makes it appropriate with V2G (vehicle-to-grid) and V2X (vehicle-to-everything) functions.
“The US and Canadian markets for EVs are frequently increasing however this development might be held again by inadequate entry to speedy DC charging stations,” stated Claude Champion, Basic Supervisor at LEM USA. “LEM understands precisely what the sector wants and has labored carefully with EVCS producers and installers when creating options just like the DCBM 400/600.”
