Looks like the battery electric bus is winning the battle at University California Irvine.

The route cancellation doesn't seem to have anything to do with the type of bus, they aren't running it with any bus from now on.

BYD, Alexander Dennis electric buses take over fourth London bus route
http://www.greencarcongress.com/2018/03/20180309-adl.html
In February, another fleet of BYD Alexaner Dennis battery-electric buses took over operation of a fourth London bus route. Route 153, operated by Go-Ahead London on behalf of Transport for London (TfL), runs an intensive service from before 05.00 to after 23.00 six days a week (with a slightly later start on Sundays).

The Route spans many of the City of London’s most congested streets between its termini at Finsbury Park in the north to Moorgate in the heart of the financial district.

The new fleet consists of 11 of the 10.8m BYD ADL Enviro200EV single deckers, similar to others operated by Go-Ahead and now a familiar sight on London roads. The well-proven zero emission vehicles entered service successfully and operate from the Northumberland Park Garage in Tottenham, north London. The new buses marked the transfer of the route to Go-Ahead from CT Plus. BYD has supplied the depot with its own-designed and manufactured charging points.

The other three ADL BYD serviced London routes, all with Go-Ahead, are the 521 and 507 from Waterloo and the 360 from Camberwell. Other routes and operators will receive fleets of BYD ADL electric buses in the coming months following tender wins by the partnership. . . .

Ingineer has posted the following video on his YouTube channel showing an electric bus which was built in 1968!



Here are his comments which accompany the video:
Ingineer wrote:1968 "Westcoaster" Bus originally electric drive, but had 36v lead-acid system and 4 golf car motors all working to drive the bus to it's top speed of 14MPH. Now the old system has been removed and a Tesla ~400HP drive unit installed to run it. I think this was used by the California Water dept. to ferry employees around underground, possibly at a dam, so they needed zero emissions.
That just makes me realize how far battery-electric drivetrains have come in the last 50 years.

Efficient Drivetrains selected to participate in $4.4M DOE program for electrification of school buses
http://www.greencarcongress.com/2018/03/20180314-edi.html

Efficient Drivetrains, Inc. announced that it has been selected as the electric drivetrain provider for a $4.4-million program implemented by the United States Department of Energy in efforts to accelerate the adoption of advanced and alternative fuel vehicles. (Earlier post.) Combined with matching funding from other public and private entities in California, the total project funding represents an electrification program over $9 million.

School buses continue to remain the largest mass transit segment in the country, carrying more than twice the number of passengers as the entire US transit and rail segments. Diesel vehicles expose the community and school children to toxic air contaminants, which are known to increase health risks. Upon completing the program, the result is a fleet of affordable, full electric zero-emissions buses that will eliminate thousands of pounds of particulate matter from the air, improving the health of the school children riding the buses, and the greater community.

As part of the program, EDI will be supplying its EDI PowerDrive 7000ev electric drivetrain in conjunction with its EDI Power2E exportable power solution to a leading school bus OEM to develop a fleet of zero-emissions electric-powered school buses with Vehicle-to-Grid (V2G) capabilities.

The bus offers 100+ miles of all electric zero-emissions driving, with the expected full power performance of its traditional diesel counterpart and requires no change to driver behavior to operate. Additionally, fleet managers will have access to real-time fleet tracking and vehicle diagnostics featuring the location, state of charge, and other valuable information utilizing the EDI PowerTracker telematics system. .

Baton Rouge orders 3 BYD electric buses
http://www.greencarcongress.com/2018/03/20180314-byd.html

. . . The bus has a range of approximately 150 miles (241 km) on a single charge and a capacity of up to 32 passengers, depending on configuration. BYD buses are projected to cost roughly $1.00 less per mile to operate than the typical diesel-powered bus.

CATS operates 29 bus lines and provides more than 2 million rides each year.

SamTrans orders 10 Proterra electric buses
http://www.greencarcongress.com/2018/03/20180315-proterra.html

The San Mateo County Transit District (SamTrans) has ordered 10 new 40-foot Proterra Catalyst E2 electric buses, which will replace 10 diesel buses. This marks the agency’s first electric bus order of many more to come, as SamTrans has set a goal of electrifying its entire bus fleet by 2033.

SamTrans’ 312-vehicle fleet carries an average of more than 36,000 people to school, work and other destinations each weekday. It operates 77 routes throughout San Mateo County . . . The 10 Proterra Catalyst buses will begin service in 2019, and serve a number of routes in San Mateo County.

. . . the new electric buses will also have a positive impact on SamTrans’ bottom line, since they require less energy to operate and reduce maintenance costs. Over their 12-year lifetime, the 10 Proterra buses will result in maintenance and operations cost savings projected at nearly $4.5 million. The purchase of these new buses is fully funded by a combination of federal, State, Bay Area Air Quality Management District and SamTrans funds. . . .

The E2 battery packs represent the heavy-duty industry’s highest pack-level energy density at 160 Wh/kg and 260 Wh/L, Proterra says.

A couple of small announcements regarding Proterra electric buses:

Breckenridge to start Proterra Electric Bus demo this week. Thursday, March 22, to be exact.

Baltimore Gas & Electric and Proterra to Deploy Nation's First Electric Shuttle Buses at a Utility Campus. It seems they had to work pretty hard to come up with a "nation's first". After all that, it's not even true given that a water utility deployed electric buses on their campus fifty years ago. :roll:

Still, I'm dumbfounded that electric companies haven't already achieved a high level of penetration of BEVs in their fleets, at least for cars. Why is that not a no-brainer for companies who make their own electricity? Don't they have an incentive to consume their own product, and thereby encourage others to do the same, rather than to purchase products from other companies which sometimes come from other countries?

Proterra has demonstrated that the combination of their large batteries and their "DuoPower Drivetrain" technology provides the ability to provide a superior replacement for ALL diesel buses on ALL routes in their prospective customers' regions:



From here on out, BEV buses no longer have a performance deficit versus diesel buses. As such, they will be able focus on cost, reliability, durability, product differentiation, and manufacturing volume.

It looks like New Flyer chose to install their batteries on the roof of their electric buses. As a result, one of them has rolled over during testing. Sorry, but that's a dumb idea which will need to be fixed.

Daimler is also adopting partial roof mounting of batteries in their Citaro BEV buses, to make it easier to use a single platform for all their HEV/BEV/FCEV/NGV buses. Presumably they'll do a better job of watching the Cg. See

CUTRIC launches $40M Pan-Canadian electric bus trial
http://www.greencarcongress.com/2018/04/20180413-cutric.html

The Pan-Canadian Electric Bus Demonstration and Integration Trial: Phase I was launched at TransLink in Vancouver as part of a national coordinated effort to advance zero emissions transit technology, spear-headed by the Canadian Urban Transit Research and Innovation Consortium (CUTRIC).

The $40-million project encompasses 18 standardized and interoperable electric buses, seven standardized and interoperable overhead chargers, and five routes in three cities, said CUTRIC Executive Director & CEO Josipa Petrunic.

CUTRIC brought together manufacturers, transit agencies, utilities, funding partners, research teams, and technology development capacities for the demonstration trial that is launching first in TransLink’s system in Vancouver, B.C. TransLink is joined by Brampton Transit and the Regional Municipality of York as sites for the trial, with Brampton Transit having spearheaded the trial planning process back in 2016. . . .

TransLink is working with two Canadian transit vehicle manufacturers (New Flyer Industries of Winnipeg, Manitoba and Nova Bus, of St. Eustache, Quebec) and two charging station manufacturers (ABB Group and Siemens Canada) to deploy four electric buses and two overhead electric charging stations that plug into an open protocol known as the OppCharge protocol—first jointly developed by Siemens and Volvo Bus Corporation.

    New Flyer is providing Xcelsior CHARGE battery-electric buses. For the purposes of the CUTRIC trial, the company is implementing an on-route rapid charging system in co-operation with ABB and Siemens who are the providers of the charging equipment. This overhead charging strategy allows the bus to essentially stay in service indefinitely and is limited only by the transit service demands.

    Nova Bus, part of the Volvo Group, is providing LFSe electric buses. Through it fast charging technology, the LFSe can be charged in less than 5 minutes at the end of route stations.

    ABB will supply interoperable opportunity charging systems with inverted pantograph technology for e-buses, rated up to 450 kW, to the e-bus demonstration project in Brampton, Ontario.

    Siemens Canada is an eBus charging solution provider for the Pan Canadian Demonstration Project. Siemens modular charging systems are available in 150kW, 300kW and 450kW configurations and include an overhead-charging interface that can charge the bus in station, while passengers exit and enter the bus. The chargers are also OppCharge compliant and in use with multiple bus OEMs. . . .

KVG Braunschweig converting around 25% of its bus fleet to electric
http://www.greencarcongress.com/2018/04/20180416-kvg.html

Lower Saxony transport-operator KVG Braunschweig will convert around 25% of its bus fleet to electric. The current fleet of electric vehicles will grow to 48 full-size electric buses by 2023; KVG intends to procure six new e-buses this year. . . .

The basis for the decision of the KVG Supervisory Board was the positive outcome of the Leo project, a trial of electric buses in line operation. Salzgitter-based manufacturer Sileo delivered three electric buses to KVG at the turn of the year 2016/2017. KVG successfully tested a Sileo S12 electric bus in line operations for cost-effectiveness, reliability, comfort for passengers and technical requirements.

The 12-meter S12 offers a lithium iron phosphate battery pack with up to 300 kWh capacity; specific energy consumption is from 0.7 to 0.8 kWh/km. Dual 120 kW traction motors propel the bus up to 75 km/h (46.6 mph). Passenger capacity is 39 seated and 51 standing.

The KVG received a subsidy of 40% of the procurement costs from the Landesnahverkehrsgesellschaft Niedersachsen mbH (LNVG) on behalf of the state of Lower Saxony for the purchase of the three existing electric buses. . . .
