Industry News NREL Teams Up on Three ARPA-E Projects to Optimize Electric Vehicle Battery Management and Controls The US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) has joined DOE and research partners in launching the Advanced Management and Protection of Energy Storage Devices (AMPED) program. Over the next three years, NREL engineers will work with teams led by Utah State University, Washington University and Eaton Corp. to optimize utilization, life, and cost of lithium-ion (Li-Ion) batteries for electric-drive vehicles (EDVs) through improved battery management and controls. The three projects are funded under the AMPED program with more than $7.4 million from DOE’s Advanced Research Projects Agency-Energy (ARPA-E). “These projects present a great opportunity for us to build on our recent R&D results and design improvements supported by DOE’s Vehicle Technologies Program and create battery systems that will let drivers go further and more safely in the next, longer-lasting generation of electric and hybrid cars,” NREL Energy Storage Group manager Ahmad Pesaran said. In addition to groundbreaking thermal evaluation and analysis, NREL’s energy storage (ES) modeling, simulation and testing activities include battery safety assessment, next-generation battery technologies, material synthesis and research, subsystem analysis, battery second use studies, and battery computer-aided engineering. Lab research improves ES devices, from materials to batteries, ultracapacitors and complete ES systems, by uncovering new ways to enhance thermal performance and lower life-cycle costs. The ultimate goal of these projects is to make EDVs viable options for a larger and wider population of drivers. Power Management of Large Battery Packs - Utah State University ($3 million) The objective is a reduction in battery size, 20 percent longer battery pack lifetime or 20 percent reduction in battery pack energy content and 50 percent increase in cold temperature charge rate. Researchers in NREL’s Center for Transportation Technologies and Systems (CTTS) will work with the Utah State University team to develop electronic hardware and control software for an advanced plug-in hybrid electric vehicle (HEV) battery management system to maximize the lifetime of each cell in a battery pack. Other project partners include University of Colorado (Boulder and Colorado Springs) and the Ford Motor Company. Laboratory testing will take place at both NREL and Ford. Battery Management System Design - Washington University ($2 million) The objective is a 20 percent increase in utilization of untapped Li-Ion battery capacity at the cell level. The Washington University team will develop a predictive battery management system with innovative control hardware that uses advanced mathematical models to optimize battery performance. The system will project optimal charge and discharge of batteries in real-time, enhancing battery performance and 22 Battery Power • March/April 2013 improving battery safety, charge-rate, and usable power capacity. NREL’s CTTS researchers will use the lab’s breakthrough battery multi-physics models to guide the design of the control algorithms and will demonstrate the capability of the algorithms through laboratory testing. Predictive Battery Management for Hybrid Vehicle Eaton Corp. ($2.4 million) The objective is a 50 percent improvement in fuel economy of heavy-duty HEVs without sacrificing battery life. Eaton Corp. will collaborate with NREL to develop a power control system to optimize the operation of commercial-scale hybrid electric vehicles (HEVs), integrating NREL battery life predictive models with Eaton HEV control algorithms. The planned approach provides a cost-effective solution that reduces the size of the battery needed for operating large hybrid electric vehicles with no loss in battery life or vehicle performance. NREL will perform hardware-in-the-loop testing in its laboratories to demonstrate the new system. ARPA-E’s AMPED program is providing a total of $30 million in funding to 14 research projects to leverage the nation’s brightest scientists, engineers and entrepreneurs to develop breakthrough energy storage. These projects focus on maximizing the potential of existing battery chemistries with innovations in battery management and storage to advance electric vehicle technologies and to help improve the efficiency and reliability of the electrical grid. Lithium Ion Batteries for Electric Vehicles Will Reach $22 Billion in Annual Market Value by 2020 In recent years, the lithium ion (Li-Ion) battery industry has taken a number of steps forward. The technology continues to improve, leading battery cell manufacturers have built new factories that incorporate advanced production techniques, and automakers have greatly increased their research and development (R&D) efforts on plug-in electric vehicles (EVs). According to a new report from Pike Research, a part of Navigant’s Energy Practice, these developments will translate into strong growth for Li-Ion batteries over the remainder of the decade. The overall market for Li-Ion batteries in light duty vehicles will grow from $1.6 billion in 2012 to almost $22 billion in 2020, the study concludes. “The Li-Ion battery looks set to be the chemistry of choice for the on-board energy storage market for the foreseeable future, taking over from nickel-metal hydride, which has been the preferred battery for hybrids to date,” says senior research analyst David Alexander. “Li-Ion batteries can supply the much greater capacity needed for battery electric and plug-in hybrid vehicles, and 2012 saw the launch and announcement of new models from many manufacturers, all featuring Li-Ion batteries.” The pressure to reduce the cost of electric vehicles is high, and the cost of the battery pack is the most important factor in determining the premium cost of EVs. Large R&D funds have been invested, but only small incremental improvements have been achieved so far.
