Coulomb Announces New Home Charger for Electric Cars

CT500-Home Charger(7/26/10)

CT500 Level II Charging Stations for Residential and Light Commercial Use Coulomb’s Advanced ChargePoint Network

Coulomb Technologies today announced the availability of its residential charging stations for electric cars. Coulomb’s new CT500 Level II ChargePoint® Networked Charging Stations are designed for home and light commercial use. The announcement expands Coulomb’s spectrum of products for EVs from home to Level III fast charging stations. CT500 charging stations will be sold through Coulomb’s OEM and distribution channels. The ChargePoint Network is based on an open interface, standards-based architecture that provides station owners with a complete set of business applications to market and bill for electric transportation fueling services, and provides drivers with EV charging applications to make fueling easy.

The home charging announcement is timely. Nissan has received over 16,000 deposits for the LEAF, including one from me. We are getting recommendations to have Aerovironment inspect our garages and plan on average installation costs of $2,000 including electrical work. GE recently entered the smart charging competition with the GE WattStation EV Charger and will soon announce its home charger.

The CT500 charging station is a 7.2 kw single output station designed for residential and light commercial applications. The station delivers Level II (208/240 V @ 30 A) charging and is compatible with plug-in electric vehicles that comply with the SAE J1772™ plug-in electric vehicle-charging standard. The station’s small size and flexible network interfaces make it an ideal solution for utilities, homeowners, fleet managers, and auto manufacturers. The CT500 is compatible with Leviton’s recently announced innovative Evr-Green™ EVSE installation system. This industry-first prewire mounting system provides for simple plug-in installation for new charging stations.

Coulomb’s ChargePoint Network is open to all drivers of plug-in vehicles and provides authentication, management, and real-time control for the networked electric vehicle charging stations. The network of electric vehicle charging stations is accessible to all plug-in drivers by making a toll free call to the 24/7 number on each charging station, or signing up for a ChargePoint Network monthly access plan and obtaining a ChargePoint ChargePass™ smart card.

All Coulomb stations including the new home charger are network-enabled, capable of reporting energy usage and communicating over the network with Software Application Services and Network Support Services to activate capabilities such as:

  • Providing open access for all drivers using any standards based RFID card
  • Generating revenue to offset electricity, capitol equipment and maintenance costs
  • Sending SMS or Email notifications to the driver for charging complete or interruptions in charging
  • Controlling access to eliminate energy theft and to enhance safety
  • Integrating with the utility Smart Grid for demand side management and preferred pricing
  • Remotely receiving software OTA upgrades to accommodate advancements in future EV charging technologies

Coulomb Technologies is the leader in electric vehicle charging systems and application services, with the ChargePoint Network now operating in 14 countries, and Network Operations Centers in the U.S., London, and Hong Kong. Coulomb provides a vehicle-charging solution, with an open system driver network: the ChargePoint Network provides multiple web-based portals for Hosts, Fleet managers, Drivers, and Utilities, and ChargePoint Networked Charging Stations ranging in capability from 120 Volt to 240 Volt AC charging and up to 500 Volt DC charging.
