Proterra launches new diagnostic tool and cold weather package for improved operational efficiency of battery-electric buses
http://www.greencarcongress.com/2017/05 ... terra.html

. . . A simple dashboard displays the vehicle’s functional layout, enabling users to monitor operation levels, see faults and resolve many issues directly through the interface without physically removing bus panels. A virtual mechanic, the Diagnostic Tool provides access to most of the vehicle’s operational features, including monitoring of the overhead charging system. . . .

To ensure safe and comfortable operation in winter conditions, the company is also introducing the Proterra Cold Weather Package . . . since the bus is electric and has no combustion engine, there is no excess heat to reuse within the vehicle. The Cold Weather Package addresses this issue with two different configurations, depending on the severity of climate.

    For regions with occasional snow and below-freezing temperatures, the Standard Cold Weather Package offers a front door and ADA ramp diffuser to remove ice and minimize slipping, heated mirrors to ensure better visibility, and a heated charge blade and scoop on the roof of the bus for consistent charging all winter.

    In areas with more extreme winter weather, such as northern or mountain climate zones, the Extreme Cold Weather Package offers the features of the Standard Package, with additional auxiliary heat for sub-zero conditions to keep riders and drivers comfortable. In addition, a heated rear exit floor prevents ice buildup. Optional features, including integrated chains and belly pans, add an extra layer of safety and operational reliability.

Motiv Power Systems to power 13 electric school buses in California pilot
http://www.greencarcongress.com/2017/05 ... tivps.html

. . . A $7.5-million grant from the California Air Resources Board (CARB) will support the building of 13 battery-electric school buses as part of the Sacramento Regional Zero-Emission School Bus Deployment Project. The 13 buses will go to Elk Grove Unified School District and Twin Rivers Unified School District. . . .

The new all-electric buses will be powered by Motiv’s all-electric powertrains . . . The buses, Trans Tech’s all-electric eSeries built on the Ford E450 chassis, will be distributed by First Priority GreenFleet. Motiv’s powertrain replaces the diesel or gasoline engine on a standard chassis. . . .

The electric school buses support a battery capacity of 85 or 106 kWh, with a range of 68 to 85 miles. The 150 kW electric motor delivers 1,200 N·m of torque (885 lb-ft). Top speed for the bus is 60 mph. . . .

$9.5M from California Climate Investments will support purchase of 10 battery-electric buses and solar charging stations
http://www.greencarcongress.com/2017/06 ... 1-arb.html

California will award $9.5 million to bring 10 battery-electric buses and supportive infrastructure to serve disadvantaged communities in the south San Joaquin Valley city of Porterville. In addition to the buses, the project will include installation of charging stations and solar panels. Funding is from the California Climate Investments (CCI), the state’s cap-and-trade program.

Manufactured by GreenPower Motor Company and expected to arrive by early 2018, the ten new GreenPower EV350 40-foot electric transit buses and the charging infrastructure will service all nine of the Porterville Transit routes in the disadvantaged communities of Porterville, East Porterville, Strathmore and the Tule River Indian Reservation. . . .

In addition to the grant amount, the project partners— GreenPower, San Joaquin Valley Air Quality Management District, and Southern California Edison—will contribute more than $7 million in a combination of cash and in-kind matching funds. . . .

Shenzhen Wuzhoulong Motors unveils 12m electric bus for China market; UQM PowerPhase DT drive system
http://www.greencarcongress.com/2017/06 ... 3-uqm.html

Shenzhen Wuzhoulong Motors, a new energy bus manufacturer, recently unveiled an electric 12-meter bus for the China market, powered by the UQM electric drive system. Wuzhoulong Motors announced this bus at the Shenzhen International Electric Tradeshow as the Wuzhoulong F2 Felicity 12-meter fast charge high performance bus.

The bus uses the UQM PowerPhase DT HD250 propulsion system with the UQM 2-speed Eaton transmission. According to Wuzhoulong Motors, with peak power of 250 kW and peak torque of 3050 N·m, this bus saves 32% in volume and 53% in weight when compared with the leading bus E-drive competitors in the marketplace. In addition to the UQM electric propulsion system, the Wuzhoulong bus adopts a lightweight design and aluminum body to realize higher EV performance. . . .


Park City Transit deploying six Proterra electric buses; battery-lease financing model
http://www.greencarcongress.com/2017/06 ... terra.html

Park City Transit has deployed Utah’s first zero-emission, battery-electric mass transit fleet, which will include six Proterra Catalyst FC+ buses.

Selected to serve the region’s renowned ski resort community, the Proterra fleet supports Park City’s and Summit County’s transition toward renewable energy and the reduction of its overall carbon footprint. With one of the nation’s most ambitious climate targets, Park City is laying a path for a net-zero carbon footprint for its municipal operations by 2022 and a Summit County area-wide net-zero carbon footprint by 2032 by implementing Proterra’s proven transit technology. . . .

Nicknamed the “Electric Xpress,” the free transit service will provide clean, quiet, and efficient transportation to residents and tourists throughout several neighborhoods, including Park City Resort, Canyons Village, Silver Springs, Silver Lake Village, Empire Pass and Park Meadows. . . .

Proterra is responsible for the performance of the batteries through the life of the lease, removing operator risk. . . .

I think battery leasing is the way to go, at least until customers have far more experience with the full life cycle of their batteries and have real-world cost data.

Volvo Buses receives order for 13 electric buses from Malmö; largest single order to date
http://www.greencarcongress.com/2017/06/20170623-v.html

. . . The Volvo 7900 Electric bus uses about 80% less energy than corresponding diesel buses and will be powered by green electricity to minimize environmental and climate impact. The bus batteries will be fast-charged at the route’s end stops, a process that takes between three and six minutes. The bus charges via the open interface OppCharge (opportunity charging), which follows the ACEA (European Automobile Manufacturers Association) recommendations. The buses will run on route 7 in the city of Malmö, a distance of 14.7 km (9.1 miles). . . .

I was at the opening ceremony today for the electric express service in Park City. The Proterra Catalyst is a beautiful machine, smooth and quiet as you'd expect. Interestingly, near as I could tell the battery pack they opted for is only about 100kwh. Comparable to a Tesla. Of course the range is only about 50 miles, but the route is only 7 miles each way, so not much range anxiety there.

Officials were tight lipped about the per unit cost but sounded like it was in the 750k range compared to a little under 500k for a conventional 40 footer. They expect to more than make back the difference in operating costs.
