USPS Gets Two More All-Electric Azure CitiVans
26 October 2005
Azure Dynamics has sold two new zero-emission, all-electric Azure CitiVans to the New York Power Authority (NYPA) and delivered them to the United States Postal Service (USPS) fleet serving the Flushing Post Office in Queens, New York.
In June, Azure delivered a prototype series-hybrid electric CRV (Carrier Route Vehicle) to the USPS for in-service evaluation of fuel economy and emissions. A to-be-delivered prototype diesel parallel hybrid drive two-ton step will also similarly be evaluated by USPS. (Earlier post.)
The Azure CitiVans (originally produced by Solectria, which Azure Dynamics acquired) are two-ton delivery trucks, replacing diesel-powered trucks used to transport mail and bulk packages between central distribution facilities and neighborhood post boxes serving the Flushing, Queens neighborhood. NYPA has supplied funding for 30 Azure electric delivery trucks already in service at postal facilities elsewhere in New York City.
The New York Power Authority and the U.S. Post Office are to be congratulated for implementing this innovative technology, which will be crucial in our post-Katrina economy. By eliminating almost 5,000 pounds of carbon dioxide and 32 pounds of nitrogen a year, each Azure CitiVan will help New Yorkers breath cleaner air and contribute to a reduction in our nation's reliance on fossil fuels.—New York City Council member John Liu, chair of the NYCC Transportation Committee
The CitiVan uses an Azure AC90 110-kW traction motor that produces 630 Nm of peak torque, with sealed lead acid batteries for storage. Peak electrical power in the drive system is 110 kW, with continuous power of 45 kW.
The CitiVan by Azure has a range of 40 miles on a complete charge, with a top speed of 60 miles per hour. To improve overall energy efficiency each vehicle has regenerative braking to capture lost energy while braking. Over the course of a year each truck will eliminate about 4,833 pounds of carbon dioxide, 32 pounds of nitrogen oxide and one pound of particulate matter. There are currently 55 Azure CitiVans in service.
With the inclusion of the new Azure CitiVans, NYPA has now helped place 17 electric or hybrid-electric vehicles in service in Queens. Two-hundred electric drive vehicles are in service in New York City. Statewide the total exceeds 770 vehicles for state university colleges, local governments, community organizations and public parks and recreation areas.
NYPA is the nation’s largest state-owned provider of electricity and supplies approximately 22% of the state’s electricity. In New York City, NYPA supplies power for public schools, hospitals, subway and portions of the Long Island Railroad commuter train systems.
