California ARB awards $9.5M to Porterville to deploy 10 GreenPower electric buses and charging infrastructure
http://www.greencarcongress.com/2016/12 ... power.html

GreenPower Motor Company Inc. announced that the California Air Resources Board (CARB) has awarded $9.5 million to the City of Porterville to deploy 10 GreenPower EV350 40-foot zero-emission all-electric transit buses on all nine Porterville Transit routes, and to install the charging infrastructure including 11 charging stations.

The EV350 40-ft bus has a 320 kWh LiFePO4 battery pack providing some 185 miles of range (300 km); the two 85 kW drive motors are from Siemens. . . .

The grant award is part of California Climate Investments, a statewide program to reduce greenhouse gas emissions while providing clean-air benefits to California neighborhoods, with an emphasis on disadvantaged communities. California Climate Investments programs are funded by the Greenhouse Gas Reduction Fund using proceeds from the state’s cap-and-trade auctions. . . .

While I'm all for this, I wonder how long it will be before any AFV bus can get by on a purely commercial basis, without relying on government grants. Seems we still have a long way to go.

King County Metro Transit to purchase 120 battery-electric buses by 2020, 73 from Proterra
http://www.greencarcongress.com/2017/01/metro.html

. . . Eight of the buses are slated to go into service this year; 12 more in 2019. Up to eight of the new 40-foot battery buses will likely operate on Metro Routes 226 and 241 in Bellevue. As part of a pilot project last year, Metro began running three all-electric buses on these routes, which serve some of the county’s densest job centers, including the Microsoft campus and downtown Bellevue.

The 40-foot Catalyst buses have an estimated range of about 25 miles, with a quick charging time of just 10 minutes. Maintenance costs of all-electric buses are expected to decline versus hybrid-diesels, primarily because they have fewer moving parts.

The 73 battery-electric buses from Proterra will cost up to $55 million, starting with 20 buses totaling $15.12 million. Charging stations to support the initial orders of those buses will range from $5.5 million to $6.6 million.

Federal funding often helps pay for Metro’s new bus purchases. Last year, King County Metro received a $3.3-million grant from the Federal Transit Administration’s Low-or No-Emission Vehicle Deployment Program to help fund some new battery buses and charging stations for three buses that are in operations on the eastside of King County.

Metro will also acquire up to nine long-range electric buses from different manufacturers to test the battery technology with a range of about 140 miles. With this approximately $7-million acquisition, Metro is challenging the industry to produce buses that can travel farther. Metro also is calling on the industry to develop 60-foot long buses, better able to replace the articulated buses that make up 55 percent of its fleet. . . .

Paris tests electric driverless minibus to fight pollution:
Two electric-power EZ10 minibuses, which can carry up to six seated passengers, were put into service Monday and will be tested until early April between the Lyon and Austerlitz stations in Paris. The GPS-guided vehicle is free and will be running seven days a week.
That's an interesting approach. Here is a link to the manufacturer's website. It appears to have four-wheel steering. Heck, it even looks French!

Here is a page with details on the EZ10:

Capacity: 12 persons (6 seating and 6 standing)
Cruising speed: 20 km/h
Maximum speed: 40 km/h
Propulsion engine: Electric asynchronous
Autonomy: up to 14 hours of operations.
Battery: Lithium-ion (LiFeP04)
Battery Charger: 230V 16A

It looks like they will be demonstrating the EZ10 in a few cities in the U.S. over the next few weeks.

Both via GCC:
Volvo Buses receives order for 90 electric hybrid buses and fast charging stations from Belgiumhttp://www.greencarcongress.com/ ... buses.html

. . . The order from TEC Group covers 55 buses for Charleroi and another 35 buses for Namur. ABB will supply 4 charging stations to Charleroi and 8 charging stations for Namur. Delivery and installation will get under way this autumn. After the delivery, the TEC Group will have ordered in total 101 Volvo electric hybrids and 15 ABB charging stations.

The customer and operator, TEC Group, previously ordered 11 Volvo 7900 Electric Hybrids along with charging stations for Namur, a system that became operational in January this year. Once the 35 new buses take to the roads, 90% of Namur’s public transport will be electrified. . . .


ABB and Nova Bus collaborating on electric buses and charging in North America; OppCharge overhead 300kW DC fast charge

. . . The order from Nova Bus is for complete 300 kW modular OppCharge common interface charging system with inverted pantograph technology and commissioning from the new ABB Campus in Montréal. . . .

Same system as above.

It seems clear now that BEV buses are the electric drivetrain of choice in China with sales of 115,700 in 2016! This number represents 20% of the total bus market in China. HEV bus sailes peaked in 2013 (and disappeared in 2015) and PHEV sailes appear to have peaked in 2015 at only 23,051.

It seems China is producing about 3X as many BEV buses each year as Nissan is producing LEAFs. BYD is now the largest Li-ion battery manufacturer in the world/url] with [/url=https://ev-sales.blogspot.com/2017/01/china-buses-2016.html]8,848 MWh manufactured in 2016, almost equally split between buses and passenger cars.

It appears H2 FCV buses are an also-ran in this market, with China's largest single deployment of those buses being only 300 units.

The city bus market is already locked up for EVs, over diesel or hydrogen.

I fully expect that in ten years, there won't even be hydrogen or diesel city busses available (beyond grossly subsidized government funded experiments).
