Coulomb Technologies Achieves New UL Listings for Two Charging Station Product Lines

Coulomb Technologies’ ChargePoint CT500 and CT2000 charging stations have been certified to Underwriters Laboratories’ new requirements UL Subject 2594. UL Subject 2594 is the safety requirement covering Electric Vehicle (EV) supply equipment.

The Level II 208/240 VAC @ 30 A CT500 residential and CT2000 stations join Coulomb’s CT2100 dual output (Level I and II combined) as certified to UL 1998, UL 991, UL 2231-1 and UL 2231-2 standards. All Coulomb products are available to order and currently shipping.

UL evaluates representative products, components, materials and systems for compliance to specific requirements, and authorizes manufacturers of compliant products to display the UL Mark on those products. Coulomb’s UL Listed product family now includes:

  • The CT500 charging station: Recently announced, 7.2 kW single output stations designed for residential and light commercial applications for the North American marketplace. The station delivers Level II (208/240 VAC @ 30 A) charging and is compatible with plug-in electric vehicles that comply with the SAE J1772 plug-in electric vehicle charging standard.
  • The CT2000 family of charging stations: 7.2 kW (208/240 VAC @ 30 A) Level II charging stations designed for public outdoor applications for the North American marketplace. Charging is delivered via a standard SAE J1772 connector and 18-foot cable.
  • The CT2100 family of charging stations: dual and simultaneous Level II (208/240VAC @ 30A) charging via the SAE J1772 connector and Level I (120VAC @ 16A) charging via a standard NEMA 5-20 outlet thereby offering the ability to charge almost any EV.



Might be interesting to write some software to let the vehicle/owner select the charge source: 110 or 240V. The decision would be made dependent on concern for time, cost or a combination of both. The software would switch between sources in keeping with the vehicle/owner profile and immediate needs.
