In an effort to help commercialize technologies for electric vehicles (EVs) through deployment and demonstration projects, the U.S. Department of Energy's (DOE's) American Recovery and Reinvestment Act (ARRA) provided funding to participating U.S. companies to cover part of the cost of purchasing new EVs. Within the medium- and heavy-duty commercial vehicle segment, both Smith Electric Newton and and Navistar eStar vehicles qualified for such funding opportunities. In an effort to evaluate the performance characteristics of the new technologies deployed in these vehicles operating under real world conditions, data from Smith Electric and Navistar medium-duty EVs were collected, compiled, and analyzed by the National Renewable Energy Laboratory's (NREL) Fleet Test and Evaluation team over a period of 3 years. More than 430 Smith Newton EVs have provided data representing more than 150,000 days of operation. Similarly, data have been collected from more than 100 Navistar eStar EVs, resulting in a comparative total of more than 16,000 operating days. Combined, NREL has analyzed more than 6 million kilometers of driving and 4 million hours of charging data collected from commercially operating medium-duty electric vehicles in various configurations. In this paper, extensive duty-cycle statistical analyses are performed to examine and characterize common vehicle dynamics trends and relationships based on in-use field data. The results of these analyses statistically define the vehicle dynamic and kinematic requirements for each vehicle, aiding in the selection of representative chassis dynamometer test cycles and the development of custom drive cycles that emulate daily operation. In this paper, the methodology and accompanying results of the duty-cycle statistical analysis are presented and discussed. Results are presented in both graphical and tabular formats illustrating a number of key relationships between parameters observed within the data set that relate to medium duty EVs.

"Abstract: The Pedestrian Safety Enhancement Act (PSEA) of 2010 requires NHTSA to conduct a rulemaking to establish a Federal Motor Vehicle Safety Standard requiring an alert sound for pedestrians to be emitted by all types of motor vehicles that are electric or hybrid. NHTSA completed acoustic measurements for hybrid and electric heavy-duty vehicles (gross vehicle weight rating over 10,000 lb.) and for electric motorcycles. This acoustic data analysis was conducted to support activities related to the PSEA. The measurements protocol used follows general procedures in SAE J 2889/1, Measurement of Minimum Noise Emitted by Road Vehicles, May 2012. Two electric motorcycles were tested at the Transportation Research Center in Columbus, Ohio. The test surface conforms to ISO 10844:2011 specifications. One electric vehicle delivery truck was tested at Navistar's Fort Wayne, Indiana, proving grounds. The test surface conforms to an ISO 10844:1994 surface that is suitable for heavy vehicles. In addition, screening data for four hybrid and electric heavy-duty vehicles were collected. The purpose of screening test was to obtain raw descriptions of the sound characteristics for a subset of heavy-duty vehicles. The measurements protocol used for the screening tests follows general procedures in SAE J 2889/1, Measurement of Minimum Noise Emitted by Road Vehicles. However the measurement protocol used for screening tests does not fulfill all the parameters stated in SAE J 2889/1. Several aspects are different, including the acoustic environment, operating conditions, test surface, number of microphones, and microphone position. Therefore the results obtained may deviate appreciably from the results obtained using specified conditions."--Technical report documentation page.

Climate change, urban air quality, and dependency on crude oil are important societal challenges. In the transportation sector especially, clean and energy efficient technologies must be developed. Electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) have gained a growing interest in the vehicle industry. Nowadays, the commercialization of EVs and PHEVs has been possible in different applications (i.e., light duty, medium duty, and heavy duty vehicles) thanks to the advances in energy storage systems, power electronics converters (including DC/DC converters, DC/AC inverters, and battery charging systems), electric machines, and energy efficient power flow control strategies. This book is based on the Special Issue of the journal Applied Sciences on “Plug-In Hybrid Electric Vehicles (PHEVs)”. This collection of research articles includes topics such as novel propulsion systems, emerging power electronics and their control algorithms, emerging electric machines and control techniques, energy storage systems, including BMS, and efficient energy management strategies for hybrid propulsion, vehicle-to-grid (V2G), vehicle-to-home (V2H), grid-to-vehicle (G2V) technologies, and wireless power transfer (WPT) systems.

The number of heavy-duty construction vehicles is increasing significantly with growing urban development causing poor air quality and higher emissions. The electrification of construction vehicles is a way to mitigate the resulting air pollution and emissions. In this book, we consider tracked bulldozers, as an example, to demonstrate the approach and evaluate the benefits of the electrification of construction vehicles. The book is intended for senior undergraduate students, graduate students, and anyone with an interest in the electrification of heavy vehicles. The book begins with an introduction to electrification of heavy-duty construction vehicles. The second chapter is focused on the terramechanics and interactions between track and blades with soil. The third chapter presents the architecture and modeling of a series hybrid bulldozer. Finally, the fourth chapter discusses energy management systems for electrified heavy construction vehicles.

Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

The US EPA and NHTSA jointly adopted greenhouse gas emission and fuel economy regulations for medium- and heavy-duty trucks. In the regulations, detailed advanced technology options are described with corresponding fuel economy and Greenhouse Gas (GHG) emission improvement goals. Alternative fuel/powertrains are the primary options available to satisfy the regulations.In this thesis, natural gas, electricity, and hydrogen fuels, as well as diesel-hybrid electric powertrains, are evaluated with respect to their fuel economy and cost. Detailed vehicle models were constructed for use with the ADVISOR models and typical driving cycles were used to simulate heavy-duty and medium-duty truck operation in urban and long haul applications. Breakeven fuel prices for various fuel/powertrain combinations were calculated and compared with reference fuel prices, in order to determine the economic attractiveness of each combination. Scenario based on Model Year (MY) 2010-2013 and projected MY 2025-2030 were developed in order to evaluate the current and future market potential for each fuel/powertrain combination. Using today's vehicle attributes (MY 2010-2013) for Class 8 trucks, the results indicated that CNG vehicles were more economically attractive than LNG vehicles for both conventional powertrains and hybrid-electric powertrains. For similar driving distances, CNG vehicles had slightly lower fuel economy than their LNG counterparts but a much lower initial cost difference because of the lower cost of CNG on-board gas storage. For medium-duty trucks, the economics results indicated that CNG conventional trucks are attractive in most urban applications for a broad range of VMT and payback time combinations. CNG-hybrid vehicles were attractive for annual travel less than 26,000 miles and paybacks of less than three years. The other fuel/powertrain combinations were not attractive because the fuel cost savings with fuels other than diesel did not compensate for the high initial cost differentials associated with the alternative powertrains. However, those EVs emit least GHG, reducing 35% and 45% CO2 emission compared to baseline vehicles, for heavy-duty and medium-duty vehicles, respectively.In the future scenarios (MY 2025-2030), future Class 8 trucks achieve 74% better fuel economy on average than today's vehicles (MY 2010-2013). The most economically attractive option for Class 8 trucks in the 2030 scenario was the diesel hybrid-electric. The natural gas conventional and natural gas hybrid-electric vehicles were also generally superior to the updated diesel technology, with the CNG SI vehicles being somewhat more attractive than the LNG vehicles. The fuel cell vehicles are attractive for most applications if the cost of hydrogen is less than about $5/kg. All the powertrains having low speed, electric drive capability are attractive for the port applications. For the medium-duty delivery trucks in 2030, the economics analyses indicated that most of the fuel/powertrain combinations were attractive with the advanced technologies, primarily due to the reductions in the component costs. The fuel cell trucks are economically attractive for almost all applications if the cost of hydrogen is less than about $6/kg. The CNG conventional and hybrid-electric trucks are also attractive under a number of circumstances especially in urban applications. Even the battery powered trucks are economically viable for a three year payback and electricity less than about 12 cents/kWh in urban applications. These results indicate that it is valuable to start investing in alternative fueled vehicles now with a view toward the future. Natural gas vehicles, especially those using compressed gas storage, are good alternative options in the short-term. Given expected technology and cost improvements in batteries and fuel cells, in the long run electric and fuel cell vehicles are the most promising future fuel/powertrain options.

This book on hybrid electric vehicles brings out six chapters on some of the research activities through the wide range of current issues on hybrid electric vehicles. The first section deals with two interesting applications of HEVs, namely, urban buses and heavy duty working machines. The second one groups papers related to the optimization of the electricity flows in a hybrid electric vehicle, starting from the optimization of recharge in PHEVs through advance storage systems, new motor technologies, and integrated starter-alternator technologies. A comprehensive analysis of the technologies used in HEVs is beyond the aim of the book. However, the content of this volume can be useful to scientists and students to broaden their knowledge of technologies and application of hybrid electric vehicles.

In the 1900s, many dairies, bakeries, and stores used electric delivery trucks. Trucks with gas engines which could go faster and haul heavier loads replaced them. Most of today’s trucks—from pickup trucks to tractor-trailers—run on diesel, made from fossil fuels. Trucks, and other forms of transportation, are using up fossil fuels fast. Fossil fuels may be gone by 2050. Trucks also cause air pollution that harms people and the planet. Electric trucks may solve the problem. They are clean, green, and quiet. The race is on for people around the world to build them. Futuristic electric trucks are coming soon to a street near you.
