The Proterra Catalyst is the company's second generation battery electric low floor transit bus. It was first launched as the 40-foot Catalyst BE40 at the 2014 APTA Bus and Paratransit Conference in Kansas City. Foothill Transit, the launch customer for the first generation bus, was the first to order the latest generation bus.

The bus can travel up to 50 miles before the standard fast charge (FC) batteries, now lithium–titanate instead of lithium-ion, need to be recharged. In February 2015, Proterra introduced an extended range (XR) option that allows the bus to travel up to 180 miles between charges. A year later, Proterra introduced an enhanced XR battery that holds 28 percent more energy at 330 kWh, allowing the bus to travel up to 193 miles. At the 2016 American Public Transit Association (APTA) Annual Meeting, Proterra unveiled their E2 (Efficient Energy) battery option with a capacity of 440 to 660 kWh that allows the bus to travel between 194 and 350 miles. This range is able to meet a full day's worth of service for some agencies.[1]

The bus's batteries can be charged enroute with a proprietary charging station, which features automatic docking.[2] The standard FC option can be fully charged in ten minutes, while the XR option can be fully charged in approximately one hour.[3] The bus can also be plugged in using a J1772 CCS charger at the garage. The E2 is only charged this way while the bus is out of service, typically when it is parked overnight, at the garage and is fully charged in three to five hours.
