- Катализатор ProTerra это батарейкой, с транзитная шина которая была построена ProTerra с 2014 по 2020 год. Второе поколение аккумуляторных автобусов Proterra, он сменил более ранний экорид в качестве флагманского продукта компании.
История
[ редактировать ] |
В 2014 году Proterra представила Catalyst, быструю заряду на 100% электрическую шину для замены Ecoride BE35. Автобус был построен на проектировании и инженерии EcoRide и доставлял более длинную, более легкую и более экономичную автобус. Автобус второго поколения измеряет 42 фута (12,8 м) или 36 футов (11,0 м) и весит приблизительно 27 000 фунтов (12 000 кг). Автобус построен из легкого, прочного углеродного композита. Общий более низкий вес помогает уменьшить износ на улицах. У него нет хвостовой трубы и запускает практически молчание.
Specifications
[edit]With the on-route fast charging system, the Catalyst can be operated continuously, 24/7, without the need to head to the depot for lengthy charge times. Catalyst buses equipped with the Fast Charge (FC) battery pack can charge at a rate of up to 500 kW.[5] The company added a 35 ft (10.7 m) model of the Catalyst to its product line in October 2015.
Catalyst is a modular system, offered with two different lengths, two different drivetrains, and seven different batteries, depending on the required passenger capacity, speed (hill performance),[6] and range, respectively.[7]

Drivetrains
[edit]At introduction, the Catalyst was equipped with a single electric traction motor, the UQM Technologies HD220.[1][8] The HD220 was rated at 220 kW (300 hp) peak power (120 kW (160 hp) continuous) and 700 N⋅m (520 ft⋅lb) peak torque (350 N⋅m (260 ft⋅lb) continuous); a later revision, designated HD220+, increased continuous power and torque ratings to 150 kW (200 hp) and 440 N⋅m (320 ft⋅lb), respectively.[9]
The DuoPower drivetrain was introduced in October 2017; it uses two electric traction motors and has a claimed 20% increase in efficiency compared to the original single-motor drivetrain, which was redesignated ProDrive.[10] As ProDrive, the Catalyst was equipped with an upgraded UQM HD250 motor,[2] which offered increased ratings of 250 kW (340 hp) peak power (150 kW (200 hp) continuous) and 900 N⋅m (660 ft⋅lb) peak torque (360 N⋅m (270 ft⋅lb) continuous).[9] The DuoPower traction motors are permanent magnet alternating current motors[11] manufactured by Parker Hannifin as part of their Global Vehicle Motor (GVM) series.[3][12]
Batteries
[edit]Buses equipped with the FC (Fast Charge) family of batteries are intended for circulator routes; XR (eXtended Range) battery buses are intended for intermediate-mileage routes; and E2 (Efficient Energy) battery buses are intended for high-mileage routes.[13] The buses were initially offered with lithium-titanate battery chemistry, which Proterra redesignated the TerraVolt FC. FC batteries can be fully recharged in less than ten minutes.[14]
The TerraVolt XR lithium nickel manganese cobalt oxide batteries[5] were introduced in 2015 with improved range but slower charging, approximately one hour to full charge.[14]
TerraVolt E2 batteries were introduced in 2016 with the longest range and slowest charging.[13] The E2 battery range features a 3–5 hour charge time.[13][15] E2 batteries have an energy density of 160 W-hr/kg and 260 W-hr/L, and use cells from LG Chem.[16]
Batteries are carried under the Catalyst chassis, and use an interchangeable mounting system, so each Catalyst can hold between four and ten battery packs. The batteries can be swapped out, upgraded, or reconfigured as needs change.[5]
Charging
[edit]
Buses can charge en route, allowing more trips and higher productivity for circulator or loop routes. One common example is to have charging stations at major transit centers. Two examples of this are the Washington Plaza Bus Terminal in New York and the Mill Woods Transit Center in Edmonton.
Charging rates range from 60 to 120 kW (using the SAE J1772 CCS ports) and from 166 to 350 kW (using a J3105 overhead fast-charger).[17][18] In 2018, Proterra began offering the OppCharge (SAE J3105-1) overhead charger instead of its proprietary "blade" overhead charger.[19]
Replacement
[edit] |
On September 15, 2020, Proterra announced the replacement to the Catalyst, the ZX5. The ZX5 40' replaced the BE40 and the ZX5 35' replaced the BE35. Edmonton Transit Service was the launch customer, ordering 40 ZX5 40' buses.
