Electric bus maker Proterra announced a new battery design for the Proterra Catalyst XR transit vehicle at the American Public Transportation Association Bus and Paratransit Conference (APTA), a gathering for U.S. transit agencies to showcase the best innovations in mass transit.
Within the same energy storage footprint as the original Catalyst XR, the battery-enhanced vehicle now holds 28 percent more energy at 330 kWh and a best-in-market lightweight vehicle body. All current Catalyst XR customers will receive a complimentary upgrade to the higher energy level.
Since establishing its battery-engineering lab in Silicon Valley, Proterra has attracted world-class engineers from leading technology companies to design batteries specifically for heavy-duty EV transit. With extensive background in mechanical, electrical and battery systems engineering, the team architected a new Catalyst XR battery pack for optimal efficiency which now delivers additional range while remaining the lightest vehicle in its class.
The award-winning bus has already achieved the best efficiency rating ever for a 40′ transit bus at 22 MPGe. Nearly six times more efficient than a diesel or CNG bus, the Catalyst is also significantly more energy efficient per mile than the closest competitors’ electric bus. Other performance benefits of the Catalyst XR2 include:
– Longest nominal range: capable of traveling a maximum of 194 miles on a single charge, based on Altoona efficiency measures. Actual mileage will vary with route conditions.
– Lightest weight: at least 2,000 lbs. lighter than any other 40′ battery electric bus on the market, while being more efficient.
– Designed for safety: Catalyst vehicles are purpose-built and engineered for the safest location of batteries—outside of the passenger compartment. The batteries are temperature-controlled and incorporate both active and passive safety systems, with ruggedized, reinforced battery packs that are further separated from passengers by a heavy-duty structural barrier.
Transit agencies interested in assessing route-specific range along with the cost savings, performance and environmental benefits of the updated Catalyst XR, can now receive accurate system-level data with the new Proterra EV Simulator, which will be on display at booth 631 during the APTA conference.
