ALABC Hybrid Electric Vehicle Demonstration Project

A hybrid electric vehicle (HEV) retrofitted with an UltraBattery® has surpassed more than 100,000 miles (160,000 km) of driving in a project run by the Advanced Lead Acid Battery Consortium (ALABC) in the United States.

The two-year project has so far demonstrated the durability of UltraBattery® in the operation of a Honda Civic HEV. The car was used as one of a fleet of courier vehicles driving daily around the Phoenix area of Arizona. During this time, the Civic had no significant loss in battery capacity, and achieved roughly the same fuel efficiency as the same model car powered by nickel-metal hydride batteries – at a significantly lower cost.

ALABC is continuing the project, and plans to keep running the HEV to see how long the batteries will last. The capability of UltraBattery® to work efficiently in the high-rate, partial state-of-charge operation required for an HEV is making it an attractive, cost-effective alternative to other battery technologies available today.
