ARB sees beginning of market penetration of battery-electric medium- and heavy-duty trucks and buses
October 16, 2015
The California Air Resources Board (ARB) has released its draft technology assessment of medium- and heavy-duty battery-electric trucks and buses. The draft assessment identifies the status of battery-electric vehicle (BEV) technology that can reduce greenhouse gas (GHG) and criteria pollutant emissions from Class 2b through Class 8 vehicles (gross vehicle weight of 8,501 pounds and up).
Overall, the assessment finds that BEVs are beginning to penetrate the medium- and heavy-duty vehicle markets. Battery electric transit buses are increasingly available from a variety of manufacturers and some school buses are commercially available. Battery electric shuttle buses are also increasingly available, as are other medium-duty BEVs, primarily delivery vehicles. Currently, BEVS in the marketplace typically use lithium-ion battery chemistries. Class 8 heavy-duty trucks remain a significant challenge, according to the report.

ABB launches automated fast charging system for electric buses; inverted pantograph
ABB is introducing an automated fast charging system which allows electric city buses to drive 24/7. With its automated rooftop connection and a typical charge time of 4–6 minutes, the system can easily be integrated in existing bus lines by installing fast chargers at end points, terminals, depots and/or intermediate stops. The modular design offering 150 kW, 300 kW or 450 kW of charging power provides any city bus with enough energy in only a few minutes to run its inner-city route continuously throughout the day.
The robust automated connection is based on a pantograph: a proven system used commonly on trains, trams and metro’s, but mounted in inverted position on a stylish infrastructure pole. When a bus arrives at the charging stop, wireless communication will be established between bus and charger and the pantograph will come down automatically. After all safety checks are performed the system will provide the bus with a powerful fast recharge. (A Combo 2 connector can also serve to link bus with charger.)

Daimler Trucks testing the first series-production semi-autonomous truck on public roads
October 02, 2015
Daimler Trucks today demonstrated the first series-production truck to operate on an automated basis—automation level 2 (partially automated driving)—on the A8 public highway between Denkendorf and Stuttgart. The standard Mercedes-Benz Actros equipped with the Highway Pilot system is approved as a test vehicle in accordance with §19/6 StVZO (German road traffic type approval law).
The version of the Highway Pilot installed in the Actros allows semi-autonomous driving. Although the Highway Pilot is able to steer the truck by itself on motorways, the driver retains full responsibility; needs to monitor the traffic at all times; and must be able to intervene at any time. Daimler compares the Highway Pilot to the autopilot commonly used in aviation.

Ricardo in EU-funded HDGAS; seeking >30kW/L, 10% improvements in power, torque and GHG in natural-gas fueled heavy-duty trucks
September 23, 2015
Ricardo is one of 19 collaborating commercial and academic partners in the European Commission’s Horizon 2020 Green Vehicle Initiative project HDGAS—a project that aims to develop, demonstrate and optimize advanced powertrain concepts for dual-fuel and pure natural gas-powered heavy duty vehicles. Particular areas of focus for the company will be the development of engine and aftertreatment systems that offer the prospect of delivering real driving emissions well below Euro VI limits for heavy duty vehicles.
Long haul trucks are an essential element of the transportation mix of modern, industrialized society. They are, however, inherently less amenable to the type of electrification and hybridization strategies that are already contributing to reduced carbon emissions and potential long-term sustainability for the light vehicle sector. A key global imperative is, therefore, the substantial improvement of heavy vehicle engine efficiency and reduction of environmental impact.

DOE anticipates making approximately 2 to 4 awards under this FOA, with the majority of funding going to electrification projects.
Area of Interest (AOI) 1: Medium and Heavy Duty Vehicle Powertrain Electrification. The objective of this area of interest is to research, develop, and demonstrate electric-drive powertrain technologies for medium- and heavy-duty Plug-in Hybrid Electric Vehicles (PHEV) and Electric Vehicles (EV) that reduce fuel consumption by at least 50% when compared to an equivalent vehicle with a conventional internal combustion engine powertrain driven on a comparable duty cycle.
Achates Power proposes EPA/NHTSA medium- and heavy-duty engine standard require 15% decrease in fuel consumption and emissions
Achates Power, Inc., the developer of a family of efficient compression-ignition opposed-piston two-stroke (OP2S) engines (earlier post), proposed more stringent engine fuel efficiency and emission standards for medium- and heavy-duty vehicles at a recent public hearing held by the National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) on “Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles – Phase 2”.
Earlier this year, NHTSA and EPA jointly announced the proposed Phase 2 standards for medium- and heavy-duty vehicles. (Earlier post.) While these vehicles as a whole will have to curb fuel consumption and carbon dioxide emissions by up to 24% between the 2018 and 2027 model years, the agencies are proposing separate engine standards requiring only a 4% decrease.
New Tandem Axle Lift function from Volvo Trucks lowers fuel consumption up to 4%
September 09, 2015
Volvo Trucks has introduced a new function—Tandem Axle Lift—that makes it possible to disengage and raise the second driven axle even while driving. This gives better road grip and up to 4% lower fuel consumption when the truck is driven without a load. The new function is designed for heavy duty transports with loads being carried one way and empty return trips—for example, when hauling timber or in construction and bulk cargo operations.
By replacing the differential in the first driven axle with a dog clutch, the second driven axle can be disengaged and raised; the tires can be lifted 140mm (5.51 inches) off the road surface. The driver thus has access to both the power and capacity of two driven axles (6X4) and also the better maneuverability of a single driven axle (4X2).

CMU study compares lifecycle GHGs of natural gas pathways for MHDVs; MD BEVs can deliver large reductions, but diesel hard to beat for Class 8
May 27, 2015
A study by Carnegie Mellon University researchers comparing life cycle greenhouse gas (GHG) emissions from different natural gas pathways for medium and heavy-duty vehicles (MHDVs) found that the GHG reduction potentials of the pathways vary sharply between non-Class 8 MHDVs (e.g., pick-up trucks, parcel delivery trucks, and box trucks), Class 8 transit buses, and Class 8 MHDVs (e.g., refuse trucks and tractor-trailers).
Battery-electric (BEVs), LPG, and CNG pathways could reduce life cycle GHG emissions for non-Class 8 MHDVs compared to the baseline petroleum fuels. Similarly, BEVs achieve emission reductions for transit buses. On the other hand, none of natural gas pathways, CNG, LNG, and F-T liquids, achieve any emission reductions per unit of freight-distance moved for Class 8 trucks compared to conventional diesel. The study is published in the ACS journal Environmental Science & Technology.
Volvo Trucks introduces automatic all-wheel drive for improved driveability and fuel economy
May 13, 2015
Volvo Trucks is introducing automatic all wheel drive—a feature it calls Automatic Traction Control—on construction trucks. ATC activates the drive on the front axle automatically when in motion, if the truck risks getting stuck—i.e., when the rear wheels lose traction on slippery or soft ground. The driver enjoys improved maneuverability, and the owner benefits from lower fuel consumption and less wear and tear on the truck.
The solution consists of software connected to the wheel speed sensors which detect and control wheel drive. When a rear wheel starts to slip, the power moves automatically to the front wheels without the truck losing torque or speed. A dog clutch activates the front-wheel drive in just half a second. The clutch is lighter and has fewer moving parts than a traditional solution with permanent all-wheel drive. If the driver encounters particularly rough ground, then it is possible to manually lock the other differentials at both front and rear.

First 18-meter electric bus in China powered by TM4 SUMO HD powertrain with external rotor motor technology
May 07, 2015
China’s first 18-meter battery electric bus has been put into service in Beijing. The Foton AUV 18-meter Harmony City BJ6180 is powered by a TM4 SUMO HD electric powertrain with a maximum torque of 3,500 N·m (2,581 lb-ft), 1600 N·m (1,180 lb-ft) continuous.
The SUMO HD is designed to interface with standard rear differentials without the need for an intermediate gearbox. Its direct drive / gearless approach makes it a good match for high-duty platform and commercial vehicle applications. The system features TM4’s external rotor motor technology (in which the rotor rotates on the outside of the stator). The external rotor motor technology delivers higher power density, high torque density, and increased long-term reliability than a similar motor with an internal rotor, according to TM4.

Study: natural gas heavy-duty trucking fleet could benefit economy, but has mixed environmental effects
February 20, 2015
Switching from diesel fuel to natural gas may hold advantages for the US heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a new white paper released by the Institute of Transportation Studies at the University of California, Davis, and Rice University.
The recent shale-driven emergence of natural gas as an abundant, inexpensive fuel in the US has raised the possibility of a “momentous shift” in the level of natural gas used in transportation. The cost advantage of natural gas over diesel fuel is particularly appealing for vehicles with a high intensity of travel and thus fuel use. In the paper, the team investigated the possibility that natural gas could be utilized to provide fuel cost savings, geographic supply diversity and environmental benefits for the heavy-duty trucking sector—and whether it can enable a transition to lower carbon transport fuels.
ICCT reviews real-world tractor-trailer fuel economy in US, China and Europe
February 15, 2015
The International Council on Clean Transportation (ICCT) has published a new paper reviewing and summarizing data on commercial vehicle sales and real-world fuel consumption for heavy-duty tractor-trailers in the three key markets of the US, China and Europe, which together account for more than 70% of HDV sales worldwide.
The review found that in the US, average tractor-trailer fuel consumption rates for the entire fleet are approximately 39 L/100 km (6 mpg). For the newest US models, fuel consumption is typically between 33 and 36 L/100 km (6.5–7 mpg). A fleet-wide analysis done for the European Commission estimates tractor-trailer fuel consumption at roughly 31 L/100 km (7.6 mpg), while tests of individual vehicles done by trucking magazines suggest somewhat higher average rates of consumption at approximately 36 to 38 L/100 km (6.5 to 6.2 mpg). Chassis dynamometer testing performed as part of the regulatory development process in China reveals that tractor-trailers seem to have much higher fuel consumption rates, on average, than in the US and the EU, with laboratory results yielding an average of 44 L/100 km (5.4 mpg).

Bus maker Alexander Dennis to fit GKN Gyrodrive flywheel hybrid systems to 250 buses; partners on international development
November 24, 2014
|Gyrodrive. Click to enlarge.|
Alexander Dennis Limited (ADL), Britain’s biggest bus and coach manufacturer, has chosen GKN Hybrid Power as a preferred partner and committed to the purchase of 250 of its Gyrodrive electric flywheel hybrid systems (earlier post). ADL will focus initially on the introduction of the low emission technology to bus fleets in London and Oxford but anticipates rapid deployment across the UK in the next few years. It will also be working closely with GKN to develop the technology for international markets.
Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. It then utilizes the stored energy to power a GKN EVO electric motor which helps accelerate the bus back up to speed, generating significant fuel savings of up to around 25% at a considerably lower cost than battery-hybrid alternatives.
