County of Sonoma Unveils Coulomb Technologies Electric Vehicle Charging Station Infrastructure for Fleet and Consumers

Seven Charging Stations Installed with Plans for up to 200 Stations in the Next Two Years

SANTA ROSA, Calif. July 2, 2009 — Coulomb Technologies today announced that the County of Sonoma, CA has become the fourth Bay Area location to deploy their ChargePoint™ Networked Charging Stations for electric vehicles. The seven charging stations are now installed throughout the County and will be used for fleet and consumer use. Along with several regional partners, the Sonoma County has applied for grant funding to install up to 200 additional stations in the next two years. Coulomb's charging stations will be officially unveiled to the public in a ribbon cutting ceremony on Thursday, July 2, 2009 at 9:00am at Sonoma County Hall of Justice (600 Administration Drive) in Santa Rosa, CA. The EV stations are at the extreme east end, adjacent to Ventura Ave.

The County of Sonoma covers more than 1600 square miles and has approximately 475,000 residents. Coulomb's charging stations are available to the public during the day, and will be used to charge county fleet vehicles overnight. The charging stations are placed at the following locations:

  • Sonoma County Hall of Justice – 600 Administration Drive (two stations)
  • Sonoma County Administration Center – 575 Administration Drive
  • Sonoma County Permit & Resource Development Department – 2550 Ventura Avenue
  • Sonoma County Department of Health Services – 475 Aviation Boulevard
  • Sonoma County Human Services Department – 3600 Westwind Boulevard

"It's no secret that the County of Sonoma is a model in the United States for the greening of fleet vehicles," said Richard Lowenthal CEO of Coulomb Technologies. "Having anticipated the County's need for an EV charging infrastructure, Coulomb worked with the County over the past nine months on fleet features for our networked charging stations. We thank the County of Sonoma for their collaboration and for making stations easily available to anyone that needs charging."

Coulomb's "Fleet Management Portal" displays performance data and graphs for their plug-in fleet managers. The networked charging stations report greenhouse gas savings and gasoline savings to fleet managers. Coulomb's charging stations notify drivers and fleet managers when individual vehicles are overdue for charging, when charging abnormally terminates, and when charging is complete.

"Our vision is to go beyond Santa Rosa, to look at the entire county and install charging stations throughout the county," said Jose Obregon, General Services Manager for the County of Sonoma. "When we send an employee out to remote locations on county business they can charge their vehicle at the same time and return on a freshly charged battery – without creating pollution."

Coulomb Technologies has developed the charging stations for municipalities, utilities, green office buildings and parking garages to allow consumers to charge their electric vehicles wherever they live, work and shop. Consumers subscribe to the ChargePointSM Network and receive a ChargePoint Smart Card that allows them to charge their car at any charging station worldwide.
