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 [[Proterra EcoRide BE35|first generation bus]], was the first to order the latest generation bus.
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 [[Proterra EcoRide BE35|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.<ref>[http://www.prnewswire.com/news-releases/proterra-catalyst-e2-series-sets-new-industry-precedent-with-a-nominal-range-of-up-to-350-miles-300325578.html Proterra Catalyst® E2 Series Sets New Industry Precedent with a Nominal Range of up to 350 Miles].

Proterra Catalyst BE40
Proterra 2014 Catalyst demonstrator-a.jpg
Years of manufacture 2014 to 2020
Length 42 feet
Width 102 inches
Power/Fuel Electricity

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 Catalyst uses a monocoque structure composed of E-glass fibre stitched non-crimp fabric and unidirectional carbon fibre in a vinyl ester resin. It is moulded using the Seeman Composites Resin Infusion Molding Process (SCRIMP), a vacuum-assisted closed infusion molding method, by TPI Composites. A gel-coat layer is first placed in the mould followed by triaxl glass fibre fabic. Unidirectional carbon fibre fabric is used to add strength at key areas. Quadriaxial quasi-isotropic glass fibre fabric is used where strength and stiffness are especially critical. The materials are vacuum bagged and infused with catalyzed vinyl ester resin. The resulting compsoite structure is lightweight and can absorb a large amount of energy in a collision.[1]

The upper body from the roof down to the lower window line, which includes the entire windshield and rear window, is on section. The lower body from the lower window line to the floor is another. The upper section of the roof and the ceiling are glass fibre sandwich structures with a balsa wood core. Components such as doors and interior fittings are attached by either molding stainless steel inserts into the laminate or by bonding.[1]

For the 2019 model year forward, the roofline towards the rear was reshaped. In addition, the vent above the rear window was no longer separated into three sections. An option that was first noted on the buses for the Toronto Transit Commission, is a rear window that can open for emergency egress.

The Catalyst can travel up to 55 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.[2]

At the 2017 American Public Transit Association EXPO in Atlanta, Proterra introduced their DuoPower drivetrain. It integrates two 190 kWh electric motors and two-speed transmission into a planetary axle from AxleTech. It boasts almost twice the horsepower as the standard ProDrive drivetrain and is five times more efficient than a standard diesel bus. With the DuoPower drivetrain, the Catalyst E2 max has a nominal range of 426 miles.[3]

The bus's batteries can be charged enroute with a proprietary overhead charging station, which features automatic docking.[4] The standard FC option can be fully charged in ten minutes, while the XR option can be fully charged in approximately one hour.[5] 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. In May 2018, to improve interoperability with other battery-electric buses, Proterra introduced compatibility with the SAE J3105 (OppCharge) overhead charging standard. [6] The roof rails to accommodate OppCharge charging are mounted on the roof near the front of the bus on trapezoidal blisters.

In 2020, Proterra restyled their line of battery-electric buses. The roofline was made more streamlined with provision for room-mounted battery packs, and additionally, integrated Oppcharge charging rails at the front of the bus. The tail light clusters on the 40ft vehicle were updated to the same design as used on the 35ft vehicle. The vehicle styling was made more angular with a flatter front end, and a recess was added under the windshield. The rated power of the powertrain options have also been increased.[7] Edmonton Transit System was the launch customer for the redesigned vehicle. The redesigned buses were formally launched as the ZX5 on September 15, 2020. [8]
