Furthermore, fundamental research projects on electrochemical energy systems are funded by the BES. It should be noted that these drives have been used for a variety of applications from steel mills to locomotives to appliances, and a great deal of development has taken place. New chemical hydrogen storage materials and regeneration processes, including ammonia borane, ionic liquids, heteroatom containing organics, catalytic processes, and new concepts for hydrogen release and spent-fuel regeneration. NRC (National Research Council). Hydrogen Program. FIGURE 3-8 Schematic of series drive configuration, typical fuel cell vehicle configurations. The fuel cell power-generation subsystem—containing the fuel cell stack and its balance of plant (BoP) consisting of the supporting air and fuel supply, thermal management, and controls—is arguably the most complex and challenging element of the entire hydrogen-fueled vehicle. Meeting these, however, is not as critical for the success of electric propulsion as is meeting the goals for HFCVs (hydrogen storage and fuel cell stack) as well as the battery for BEVs. The program also includes life-cycle issues, energy efficiencies, safety, and the environmental impact of the applied hydrogen storage technologies. Furthermore, finite-element modeling of stresses and heat flow in fires, investigative work on wraps (i.e., translation efficiency), and analysis of applicability of compressed-gas storage to specific vehicle types would be beneficial. Report No. The hydrogen storage program is one of the most critical parts of the hydrogen/fuel cell vehicle part of the FreedomCAR and Fuel Partnership—both for physical (compressed gas) and for materials storage. Vehicle fuel cell requirements can be, and usually are, different and more challenging with respect to cost, reliability, and manufacturability when compared to the other nonvehicle applications. The power thus produced is either directly utilized for various activities or is stored in a suitable battery pack for future use. In the case of hybrid electric vehicles, both oil and engine coolants are available. We recommend that lightweighting materials research funding not be redistributed to support other technology areas. To complicate the assessment of future cost further, the fuel cell stack is dependent on the platinum metals markets and on ever-changing global metals markets dynamics. The technical team has had difficulty specifically addressing its cost target. The work on a scalable inverter is a contract of $8.2 million ($4.952 million provided by the DOE and $3.258 million by the contractor) that runs from October 2007 through March 2011 (Taylor, 2009). Steady progress is being made in the advancement of power plants that rely on energy carriers other than liquid hydrocarbon (HC) fuels. The silicon-on-insulator (SOI) project is producing a gate driver circuit to function at temperatures of 200°C (the project is ongoing at ORNL, and hardware exists). They are: All the above mentioned suspension types differ only by construction. In addition, a large number of auto companies have announced their intention to launch HEVs, PHEVs, and BEVs using Li-ion batteries in the next few years. The general focus of the ACEC technical team’s work to achieve these targets continues to be lean-burn, direct-injection engines for vehicles fueled by diesel, gasoline, and biofuel or other alternative fuels, provided appropriate carbon emission mitigation is accomplished during their production. Early market applications will. Recommendation 3-9. These motors are the workhorses in almost all industrial applications. Hydrogen basic research is well funded in the FY 2009 program, and new concepts will continue to be supported. Novel materials for hydrogen storage were a high-priority area for BES funding, receiving $8.0 million in FY 2008 and $9.0 million in FY 2009. a As reported to the committee at its August 4-5, 2009, meeting and by S. Satyapal, DOE, Hydrogen Program Overview, Annual Merit Review and Peer Evaluation Meeting, May 18, 2009, Washington, D.C. All aspects of the engine operation are being pursued. Available on the Web at . New focus and funding should be given to compressed-gas storage in order to meet near-term needs for hydrogen storage. Bandivadekar, A., K. Bodek, L. Cheah, C. Evans, T. Groode, J. Heywood, E. Kasseris, M. Kromer, and M. Weiss. The ambient systems (the current and simplest configuration) are targeted for the early introduction of the vehicle test fleets. Available on the Web at . Although the BES mandate on energy storage is broader and longer term, it works in close coordination with the VT program to advance the energy storage needs for automotive applications. In 2009, the partnership changed direction and stepped up efforts to advance, in the shorter term, technologies for reducing petroleum use in combustion engines, including those using biofuels, as well as batteries that could be used in plug-in hybrid-electric or all electric vehicles. The Hydrogen Storage Engineering COE is a timely use of resources and fits well with the other COEs. Recommendation 3-13. The continued refinement of prior generations of the MEAs is a major issue, as neither the earlier nor current versions have been shown to meet simultaneously the 2015 targets for performance, lifetime, reliability, and cost. With that said, what has been reported is that, overall, the OEMs have shown increased power density for the fuel cell stack and BoP, while at the same time the packaging and operating modes have become quite sophisticated. The BES budget within the Office of Science also included support of Basic Energy Research Needs for the Hydrogen Economy ($38.3 million in FY 2009). AuYeung. d Stated ambient temperature plus full solar load. For example, Berger et al. 35 MPa and 70 MPa) compressed hydrogen. Selection criteria were established based on the potential to meet 2010 technical targets. The autonomic nervous system consists of three subsystems: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system. In other words, each 1 percent weight reduction in the BIW yielded a 3 percent increase in cost. Available on the Web at . Wade, 2001. The high voltages used in HEVs require many more Li-ion battery cells in series than is typical in smaller electronic equipment for which chargers are commonly used today. The primary focus of the hydrogen storage program within the FreedomCAR and Fuel Partnership is to drive the development and demonstration of commercially viable hydrogen storage technologies for transportation and stationary applications. The simulation currently being used is KIVA III, developed by the U.S. Department of Energy (DOE). Development of Power Control Unit for Compact-Class Vehicle, SAE 2009-01-1310, April. Share a link to this book page on your preferred social network or via email. The Partnership should continue to focus on activities to reduce the cost, size, and losses in the power electronics and electrical machines. Public domain contractor reports should be available through links on the DOE EERE Web site. There appears to be relatively little work in the Partnership on battery charging. See, for example, . The Partnership and the VT program should now follow up by initiating a research program on improved processes for reducing cost and recovering useful materials from this effort. The power thus produced is either directly utilized for various activities or is stored in a suitable battery pack for future use. Although significant progress has been recorded in the Li-ion battery performance, durability, and safety, there has been no improvement in the cost of battery.12 The projected cost at 100,000 units per year for the HEV application remains at higher than $900, almost twice the 2010 target of $500.13 It should be noted that as volume builds up the costs are likely to come down. In addition, as new power plants with alternative energy carriers are developed, produced, and introduced into the market, there will be a significant time delay associated with their market penetration. Public acceptance will demand stringent health, environmental, and safety standards, especially since one of the main reasons for hybrid vehicles is environmental. The motor is a permanent magnet brushless motor with 2 poles, thus requiring switching devices operating at a minimum of 2,750 hertz (Hz). Different types of steering systems are: To slow down or to completely stop a vehicle one needs braking a system.

Cambridge, Massachusetts: MIT Laboratory for Energy and the Environment. catalysts to address the cost, reliability, and durability challenges is reflected in the current budget. Conversion of this power to mechanical power to drive the wheels requires power electronics and one or more. See for example . The core stack technology advancement appears to be one of the most significant achievements reported to date. As noted in Chapter 1, in the United States the vehicle fleet turnover in recent years is estimated to be about 15 years.2 Consequently the turnover time for completely new vehicle architectures to achieve significant market penetration will be measured in multiple decades (Bandivadekar et al., 2008; Weiss et al., 2000). These goals, if attained, are likely to require new transportation energy carriers (fuel[s] and/or electricity) utilized in more efficient power plants in lighter vehicles having reduced power requirements and equivalent utility and safety. The current status of promising hydrogen storage materials is shown in the composite Figure 3-4. Electrochemical energy storage technologies, batteries, and ultracapacitors are critical to the advancement of the FreedomCAR and Fuel Partnership’s long-term goals. This field test included data analysis by NREL and SRNL through a collaborative research and development agreement (CRADA). In order to couple an engine running at high speed and a gear system running at low speed, we introduce a clutch which connects the engine and the gear non-rigidly. Automotive Subsystems Johnson Electric develops innovative solutions for global market leaders in automotive lighting. FIGURE 3-3 Structure of the National Hydrogen Storage Project. This tool is critical to integrating the new understanding of combustion and emission processes into a framework that allows it to be used to guide further research and identify fuel and engine operating conditions that will maximize reductions in fuel consumption over the entire operating range of the engine. The ACEC technical team is doing a good job of maintaining a close and constructive working relationship with the stakeholders within the vehicle and energy community. The focus of these projects is primarily to develop high-energy-density batteries. In most of the cases the engine is an Internal combustion type that converts chemical energy of fuel into mechanical energy. Tags: Question 4 . The VT program, in collaboration with the United States Advanced Battery Consortium (USABC), manages the electrochemical energy storage technology program with a goal of the advancement of battery technologies, to the point that the program partners are encouraged to introduce hybrid and electric vehicles with large market potential. Although it may be argued that this is postcompetitive activity, in the committee’s view some work needs to be done to ensure safety and to explore rapid charging. In contrast to conventional vehicles or HEVs, PHEVs are able to drive on electric power alone for some distance, depending on the electric battery storage capacity. Technical barriers that still remain for the fuel cell stack are membrane and electrode life and cost. In BEV applications the vehicles run on electricity only, and thus high-energy-density batteries are required. Available on the Web at . The DOE agreed with most of the recommendations from the Phase 2 review (DOE, 2009c; NRC, 2008). The analysis should be updated on a regular basis as the cost structures change as a result of process research breakthroughs and commercial developments. As this technology is not yet fully developed, advancements are needed to meet the established efficiency, durability, lifetime, and cost targets. The challenge to the materials technical team is to generate a cost-neutral 50 percent vehicle weight reduction. The overarching goals, technical targets, and program structure of the ACEC technical team are basically the same as reported in the Phase 2 review of the program (NRC, 2008). It was unable to. Let us understand it this way. Significant improvement in their performance can result in battery electric vehicles (BEVs), one of the ways to meet the Partnership’s goal of “energy freedom, environmental freedom, and vehicle freedom.” The FreedomCAR and Vehicle Technologies (FCVT) program (now renamed the Vehicle Technologies [VT] program), has supported the advancement of batteries and ultracapacitors from the beginning as a key to developing hybrid electric vehicles (HEVs). For example, the economics of recycling current Li-ion batteries is driven by the value of the cobalt contained in the battery (see, e.g., Anderson and Wade, 2001; Xu et al., 2008). The program also includes several independent projects that are not associated with any of the COEs (see Figure 3-3). However, two separate DOE-funded studies, with independent oversight, have concluded that at volumes of 500,000 units per year, the cost per kilowatt for the fuel cell subsystem, including the fuel cell and BoP, will be approximately $60-$70/kW (Satyapal, 2009; James and Kalinoski, 2009; Sinha et al., 2009). TABLE 3-1 Selected Fuel Cell Stack Targets and Progress, Projected system costs (500,000 units produced per year; $/kW). Recommendation 3-19. Understanding how auto parts work together to form automotive systems allows drivers to confidently discuss automotive problems with their mechanics. Others are safety related (air bags).

Current membranes have a greater degree of robustness but are still impacted by secondary reactions, which can lead to chemical attack and therefore failure. “Development, Test and Demonstration of a Cost-Effective, Compact, Light-Weight, and Scalable High Temperature Inverter for HEVs, PHEVs, and FCVs.” DOE Annual Merit Review and Peer Evaluation Meeting, May 21. Annual Progress Report for 2008, Energy Storage Research and Development (January). Conventional vehicles have a large number of electrical systems to control emissions, passenger comfort, and safety that are not discussed here. Computer simulation was used to ensure that stiffness and crashworthiness requirements were met. New concepts, cost-reduction R&D, and alternative engineering approaches must remain the focus of the DOE funding, especially for the development of next-generation technologies. Pending fuel economy standards will impact the vehicle mix as the on-the-road light-duty vehicle fleet turns over. All targets (weight, volume, efficiency, cost, packaging, safety, refueling ability, etc.) Vehicle requires more power when it just starts to roll (it needs to overcome inertia). The organizational structure of the team’s activities involves memoranda of understanding (MOU) between companies and government laboratories, working group meetings, regular intergroup reviews, and an annual peer-reviewed research meeting. These increased efforts will require increased funding for high-energy batteries and include leveraging all other efforts on electrochemistry and energy storage materials efforts within the DOE and the larger electrochemistry community. The objective in designing new magnetic materials is to reduce two sources of loss, known as (1) hysteresis and (2) eddy current. Available on the Web at . In order to address the fuel storage needs of and to set priorities for fuel cell applications, the EERE plans to conduct a Request for Information (RFI) and a workshop during FY 2010. The hydrogen storage technical team and the DOE provide guidance for the work of the COEs. Also, before a hydrogen fuel infrastructure is fully developed, plug-in hybrid electric vehicle (PHEV) and BEV technologies, which would compete with hydrogen fuel cell vehicles, may offer a transitional means to improve fuel efficiency and emissions reduction. The DOE should incorporate more of the advanced, most recent, nonproprietary OEM system configuration specifications in the various systems and cost models for fuel cell power plants. is aimed at understanding the fundamental changes that occur in ignition and emission-formation processes when different compounds, such as methyl esters that are found in biofuels, are used in the engine. Doped silicon (Si) devices are universally used, and the junction temperature needs to be kept below 125°C. For fuel cell systems, purity meets SAE J2719, Information Report on the Development of a Hydrogen Quality Guideline in Fuel Cell Vehicles. Permanent magnets: The emphasis will be more on molded high-strength magnets. Drive train helps to transfer power produced from the engine to the wheels with the help of intermediate linkages. It does not focus on any power devices—that is, switches or diodes. The Partnership’s budget for electrochemical energy technologies has increased as the importance of PHEV battery development has increased. To conduct such a program successfully requires close coordination among industry, government laboratories, and academia. Complete laboratory-scale prototype system and evaluation against 2015 targets is scheduled for the fourth quarter of 2015. starting the car. Lithium-ion battery technologies hold promise of achieving the long-term goals of high power, energy, and other performance requirements for HEV and PHEV applications at lower anticipated costs than those for other battery systems. Recommendation 3-18. The 50 percent weight reduction is critical to reaching FreedomCAR goals for fuel consumption and emissions. This subsystem provides security services to and enforces security policies on the SoC. Not only topic-specific understanding but also an understanding of the system-level interactions among the energy carrier, the energy release process, and the final emission cleanup are critical to continued improvement of the ICE power train.6 Continued close collaboration between the DOE and industry is necessary to allow newly developed technologies to transition into the industrial laboratories and to lead to the identification of new areas where enhanced understanding will be the most beneficial. The major systems of an automobile are the engine, fuel system, exhaust system, cooling system, lubrication system, electrical system, transmission, and the chassis. 2000. Fuel consumption would then be expected to be reduced by at least 6 percent, resulting in a new fuel economy of at least 26.6 mpg. 2009. The gearbox helps to multiply or divide the available torque at several fixed ratios. The vehicle is then redesigned to achieve a 10 percent weight reduction using lightweight materials and/or better structural utilization. Kim, G., and K. Smith. a Generally the “full” mass (including hydrogen) is used, for systems that gain weight, the highest mass during discharge is used. As the engine is connected to the wheels rigidly through gears, the engine also moves slowly. The FreedomCAR and Fuel Partnership focuses on electric drives that require a source of power that provides direct current at voltages of the order of 200 to 450 V. As shown in Figures 3-6 through 3-10, the vehicle power source is a fuel cell, an engine-driven generator, or a battery. In a parallel drivetrain, there is a direct connection between the engine and the wheels. The use of electric propulsion places increased emphasis on. An industry manufacturer has not been identified yet. Some cars have mapping computers that connect to GPS satellites. Recommendation 3-6. The concept for a scalable inverter is that it can easily be scaled to meet different power levels. Ready to take your reading offline?
