The lithium nickelate system has the highest energy density, and the lithium iron phosphate is considered inherently safer than the other two systems. Since the success of HFCVs is not assured, this transition role could turn out in many cases to be a more permanent scenario. Hydrogen storage is shown together with the new targets (volumetric and gravimetric capacity only). The operational range for LTC has been enhanced through active cylinder valve actuation and intake boosting. b 2003 US$; total cost includes any component replacement if needed over 15 years or 150,000 mile life. The two cases of high power-to-energy ratio and the high energy-to-power ratio battery characteristics for PHEV applications are listed in Table 3-5. 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. ANL is developing a one-fifth scale pilot operation to assess how to recover residual metals and polymers from the residue from shredders. Conventional vehicles have a large number of electrical systems to control emissions, passenger comfort, and safety that are not discussed here. Development of Power Control Unit for Compact-Class Vehicle, SAE 2009-01-1310, April. must be met simultaneously. The punching and assembly of laminations is expensive, and for years the “holy grail” of soft magnetic materials has been to discover a new material that has both high electrical resistivity and high permeability at the flux density levels needed. 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. Overall the number of HEVs sold has increased 271 percent from 2004 to 2008—from 84,000 to 312,000 vehicles—yet this represents only about 2.5 percent of the new vehicles sold in 2008. As the majority of on-road vehicles were tested in moderate climates, additional assessments of performance in all-weather conditions are needed to provide additional insight into the viability of the current technology path. Heating and cooling system A heating and cooling system that can let that automobile become warmer or cooler. SOURCE: DOE (2009a), Section 3.3, Hydrogen Storage. Such a design is being considered by Toyota in a plug-in version of the Prius. Also of note, the DOE Vehicle/Infrastructure Demonstration Program reported having achieved an HFCV range of 196 to 254 miles. 2009c. Programmatic issues relate to the coordination and execution of the high-risk research in order that the solicitation timing and content address updated requirements of the Partnership. The budget was increased from $24.4 million in FY 2006 to $40.8 million in FY 2007, with a significant increase primarily for PHEV batteries. The vehicle propulsion system activities are focused on attaining specific hybrid vehicle traction drive performance targets (see Figure 3-5) over the next 10 years for cost, gravimetric and volumetric density, and efficiency through advancements in materials, system design, and component technology. 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 cost of high-quality carbon fibers: Needs to be reduced. In the subsection below, Figures 3-6 through 3-10 show the major different configurations that apply to each. 2009. The simulation currently being used is KIVA III, developed by the U.S. Department of Energy (DOE). A High-Performance Interior Permanent Magnet Machine for Hybrid Vehicles. The new emission standards will require that the vehicle emission target will need to be changed from Tier 2 Bin 5 to Tier 2 Bin 2. The vehicle is then redesigned to achieve a 10 percent weight reduction using lightweight materials and/or better structural utilization. The targets for the project on magnesium power-train components have been to replace aluminum components with magnesium for a minimum weight savings of 15 percent and a cost penalty of less than $2.00 for each pound saved. Available on the Web at . Generally in most vehicles the front wheels(or the front axle) are steered and the rear wheels follow it. inherent trade-offs among the various requirements. They will reduce the fuel consumption associated with their use, and they will allow the engine to be tuned differently with an attendant increase in efficiency. The project has demonstrated a novel composite microstructure to minimize eddy current losses. Low-loss soft magnetic materials. In a PHEV application the available energy, which is proportional to the all-electric range of the vehicle, is a more important requirement than the power is. Newer, lower-cost membrane development activities have been funded in recent years, and although the results of such. 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. A full vehicle study is needed by FreedomCAR to assess the estimated overall cost penalty. Public acceptance will demand stringent health, environmental, and safety standards, especially since one of the main reasons for hybrid vehicles is environmental. Technical tasks have been established that address each of these issues. The program approach of using the Hydrogen Storage Engineering COE to fabricate and evaluate complete vehicle-ready test systems is an excellent technique for selecting the most viable material configuration. As discussed in further detail in the section below on “Electric Propulsion and Electrical Systems,” a series drivetrain powers the vehicle only by an electric motor using electricity from the battery. The down-select for onboard reversible hydrogen storage materials and for chemical hydrogen storage approaches with the potential to meet 2015 targets is set for the fourth quarter of 2013. 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. Recommendation 3-8. Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. The focus is on the two subsystems—battery chargers and system controllers—used in hybrid, electric, or fuel cell vehicles. Also, full battery system development is done in collaboration with the USABC through competitive subcontracts that are at least 50 percent cost-shared. Yet, because of the nature of the DOE multiyear funded solicitation process and the rapid advancements by the OEMs, there can be a divergence of the currently funded efforts and the fuel cell subsystem R&D needs. Certain vehicles even completely convert the engine output to electricity and then use that electricity to drive a motor for propulsion (Diesel train engines). The combination of simple subsystems and modules results in a vehicle model with a minimum number of data and a very good run time performance. This requires accurate control and manipulation of all engine control parameters for each operating condition. Recommendation 3-2. These vehicles operate in both modes—electric-only (as in a BEV) and electrical/mechanical (as in an HEV)—and the battery can be recharged from a standard electric outlet. This is obviously important because capturing energy dissipated in the brakes through regenerative braking is essential for the efficient use of the prime-mover energy. By providing a smoother working condition, the suspension enhances the life of all components which are mounted on the chassis, viz. Good progress is being made by the ACEC technical team in meeting the technical targets. Available on the Web at . Budget information provided to the committee by Christy Cooper, DOE, January 13, 2010. Furthermore, such component costs are not benefiting from established volume manufacturing operations at this time. The electric propulsion system consisting of power electronics (combinations of a bi-directional dc (direct current)-dc converter, boost converter, and inverter) and one or more electrical machines is needed for HEVs, PHEVs, HFCVs, and BEVs, to provide traction to the wheels from the prime mover. f All targets must be achieved at end of life. However, there are important differences between consumer and automotive battery efforts and applications. The most popular type of engine is referred to as the Internal Combustion Engine. The materials team needs to evaluate how the cost penalty changes as a function of the percent weight reduction, assuming that the most effective mix of materials is used at each step in the weight-reduction process. At a production of 500,000 annual units, the projected cost of the CEM is $293 and the cost of the controller is $303, with a total cost of $705 including assembly ($31) and a markup (15 percent for the CEM and 10 percent for the controller). Due to its high band gap and operating temperatures that exceed 250°C, silicon carbide (SiC) offers power inverter efficiencies over silicon. It is critical for the technical team to maintain this collaboration and to look for ways to make it even stronger. However, materials research for projects that show a high potential for enabling near-term, low-cost mass reduction should continue to be funded. Available on the Web at . During this transition the dominant power plant for mobility systems will continue to be ICE vehicles fueled with a hydrocarbon fuel (e.g., gasoline, diesel fuel, or biofuel).3. “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. To accomplish its objectives, emphasis has been on better packaging, cooling, materials, and devices. Recommendation 3-21. All of the HEVs available use a nickel metal-hydride (NiMH) battery, and the DOE has been involved in the advancement of this technology since the 1990s. The Partnership should conduct a project to evaluate the effect of battery charging on lithium-ion battery packs as a function of the cell chemistries, cell geometries, and configurations in the pack; battery string voltages; and numbers of parallel strings. 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. As a result, aside from the open reporting of such performance data and improvements, the contributions of the publicly funded programs and the degree to which the results impact the success of the OEMs related to efficiency, durability, lifetime, and cost are not known with certainty. The autonomic nervous system consists of three subsystems: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system. See and . erative pulse power rating, calendar life as measured by accelerated testing, and increased cycle life. Improved Windings. A PHEV battery cost assessment was conducted by TIAX for the DOE (Sinha et al., 2009). The CEM project incorporates a high-speed drive (165,000 rpm) with a fairly low projected cost. TREMEC offers fully integrated systems and components to control the torque transfer in all types of vehicles, from specialty gears and shafts, clutch assemblies, hydraulic control systems and solenoid valves, to control software that controls the whole system. FIGURE 3-10 Schematic of typical power-split hybrid or plug-in hybrid electric vehicle power-train configuration (such as Prius, Escape, and others). The predictive capabilities of the current CFD codes are very good. To overcome some of these limitations, a configuration known as interior permanent magnet (IPM) designs has evolved. Doped silicon (Si) devices are universally used, and the junction temperature needs to be kept below 125°C. “blocking” technology for vehicle introduction. The PHEV architecture plays an important role in the design of the battery and how it stores energy from the grid, the gasoline engine, or from regeneration during braking. The DOE was correct in providing $9.5 million for the hydrothermal recycling of Li-ion batteries through the ARRA program. of the zeroing of the primary budget line items related to the fuel cell development activities (in the FY 2010 administration’s budget request). It should be noted that Honda has teamed with Rohm and Haas to develop inverters using SiC devices because of the increase in efficiency as well as the reduction in size because of easier cooling that can be attained in inverter applications. 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. 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. On the Road in 2035: Reducing Transportation’s Petroleum Consumption and GHG Emissions. The FY 2009 budget was divided as follows: 37 percent for power electronics and 21 percent each for traction drive system, electric machines, and thermal management. Their working principle is same, i.e. The team includes members McCleer Power and the University of Wisconsin-Madison. The newly organized Hydrogen Storage Engineering COE has taken on the coordination of the engineering aspects of material-based hydrogen storage systems. Issues for high-pressure tanks that may have nearer-term application and can benefit from exploratory research are also included. Three Li-ion battery chemistries classified by the cathode material, including (1) lithium nickel, cobalt, and aluminum; (2) lithium iron phosphate; and (3) lithium manganese spinel and a carbon anode have been developed and tested for HEV applications.
