Design changes ZX5 The ZX5 is built using the same composite structure as the Catalyst, consisting of
fiberglass with a balsa-core sandwich construction, with minor changes to the roof to accommodate a roof-mounted charging rail and
battery. Inside the bus, the roof is 6 inches (150 millimetres) shorter than other buses to allow for the charging capabilities. The ZX5 comes available in three different battery capacities: • ZX5 (220
kWh): With a stated range of 232 and 240 miles (373 to 386 kilometres) of range. • ZX5+ (440 kWh): With a stated range of 232 and 240 miles (373 to 386 kilometres) of range. • ZX5 MAX (660 kWh): (Only available in 40 ft variant) With a stated range of up to 329 miles (529 kilometres) of range. Each ZX5 battery capacity is offered with either two
Parker Hannifin GVM310
electric motors (DuoPower), or a single
UQM Technologies HD250 (ProDrive) motor. DuoPower models use two independent motors, with an anergy consumption equivalent of 13.9 to 25.1
mpg-e (242 to 134 kW⋅h/100 mi), though the mileage depends on battery and body length. ProDrive models use a single motor with slightly lower equivalent efficiency, from . In August of 2023,
Proterra declared bankruptcy. During this period, the bus manufacturing division of the company was purchased by
Phoenix Motorcars, which now produces the ZX5.
Charging The ZX5 is charged using the
SAE J3105 (OppCharge) overhead charging protocol while stopped on a layover (opportunity charging), or with a plug-in
J1772 CCS DC fast charger when parked in a storage yard. With any battery option, the ZX5 may be fully charged in about 2.9 hours using the OppCharge system, which offers a maximum charging rate of 330 kW. One CCS charge port is standard at the rear curbside corner and an additional CCS port can be added either at the front curbside or rear streetside corner. == References ==
