The Proterra EcoRide BE35 is a 35 foot (11 m) (nominal length) fast-charge battery electric bus that seats 38 (including the driver) with a total passenger capacity of 60 in its composite low floor body. Foothill Transit was the first transit agency to operate the buses in revenue service, starting in September 2010. It is the first 30 ft (9 m) or larger, heavy-duty all-electric bus ever to complete federally required durability, reliability and safety testing at the Bus Research and Testing Center in Altoona, Pennsylvania. The 12yr/500,000 miles (800,000 km) STURAA test was completed on March 5, 2012.
The BE35's electric traction motor draws from lithium-titanate batteries supplied by Altairnano that can be recharged in 5–10 minutes while stopped at a bus stop via overhead terminals connected to a charging station, without driver involvement. The quick charging during a brief layover typically enables a further 26 miles (42 km) of operation.
