Cummins has started delivering a total of eight all-electric vehicles to the United States Postal Service (USPS).
The fully-electric Cummins PowerDrive-equipped vans are expected to eliminate vehicle emissions and reduce fuel and maintenance costs— under a pilot programme supported by a grant from the California Air Resources Board to the San Joaquin Valley Air Pollution Control District.
The programme is administered by clean transportation non-profit group Calstart.
The Cummins-powered vans will be in service by 31 March, 2019. The vans have an all-electric range up to 85 miles with a full load on urban drive cycles typical of USPS collection vehicles, Cummins said.
The direct drive architecture provides improved performance over the gasoline-powered version in critical areas of power and efficiency. The vans use the same charging system as passenger electric vehicles (SAE J1772 Level 2) and can reach a full charge in about eight hours, making overnight charging a viable option.
