DTE Energy Deploys EV Charging Stations

January 19, 2010

DETROIT --- Coulomb Technologies and Shocking Solutions, both leaders in the realm of electric vehicle charging, announced that six ChargePoint networked charging stations have been deployed by DTE Energy at their Detroit headquarters and at an Ann Arbor facility. 

The stations will support a study on the effects of vehicle charging on the electrical grid. The study is funded under a grant from the Michigan Public Service Commission.  

The ChargePoint stations will charge vehicles by a standard extension cord connected to the vehicle (Level 1) and at a higher voltage for a faster charge by the industry standard SAE J1772 connector (Level 2).  

"We are extremely pleased to be working with a premier utility company like DTE Energy," said Richard Lowenthal, CEO of Coulomb Technologies. "Michigan has positioned itself as an industry leader in supporting the development and adoption of plug-in vehicles and the necessary supply chain. Our ChargePoint networked charging stations are a perfect complement to these efforts. We are diligently working across the country with our distribution partners laying the groundwork for the necessary infrastructure to welcome plug-in vehicles to the market this year." 

Coulomb Technologies is a leader in electric vehicle charging station infrastructure. 

The 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 through multiple Web-based portals for hosts, fleet managers, drivers and utilities. 

ChargePoint network features include:

  • Charging status by SMS text or e-mail notification
  • Location of unoccupied charging stations via smart phones
  • Authenticated access to eliminate energy theft
  • Authorized energizing for safety
  • Smart grid integration for utility load management with future V2G capabilities.

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 smart card. Other future payment options include using any smart (RFID) credit/debit card to authorize a session or using a standard credit or debit card at a remote payment station (RPS) to pay for charging sessions.

"DTE Energy is one of the country's most progressive utilities and it has been a pleasure working with their team on this project," said John Auld, CEO of Shocking Solutions.  

Shocking Solutions is a leader in plug-in vehicle infrastructure solutions and consulting.
