8:35 How Harmful Are Carbons in EFB for High Temperature Use Cases?
Eckhard Karden, Ph.D., Technical Expert Battery & Energy Storage Technology, Advanced Power Supply & Energy Management, Ford Research & Advanced Engineering, Europe
This paper will present a novel approach to derive high temperature durability requirements from practical use cases in state-of-the-art micro-hybrid vehicles. Simulations of realistic current/voltage/temperature profiles, with a weekly assessment of weight loss and resistance increase, will be shown for a variety of EFB types with and without carbon additives.
8:55 Water Consumption Testing and Analysis
Dirk Uwe Sauer, Ph.D., Professor and Chair, Electrical Engineering and Information Technology Department, RWTH Aachen University, Germany
9:15 Tailored Carbon Additives to Meet Requirements for High DCA and Low Water Loss – Wish and Reality
Jochen Settelein, Ph.D., Research Scientist, Center for Applied Electrochemistry, Fraunhofer Institute for Silicate Research ISC
Carbon additives for the negative active mass in modern lead-acid batteries are state-of-the-art. However, due to electrolyte decomposition there is a limit in further optimization of the dynamical charge acceptance. We will discuss if it is possible to design carbon additives to attain that ambitious target without increasing the water loss. By combining investigations on pure carbon electrodes and laboratory test cells one can correlate the electrochemical activity with the physical and chemical properties of the carbon particles and open the door for the development of tailored additives.
9:35 A New Generation AGM Batteries with Enhanced Carbon Additive for µ-Hybrid Application
Olaf Sielemann, Director, Transportation R&D Europe, Exide
EXIDE Technologies is working on optimization of VRLA AGM batteries for µ-Hybrid application. The feedback from the application on AGM batteries is in general excellent. One behavior, the capacity and rechargebility loss cause by sulphation, is mentioned frequently by OEM’s to be improved. The presentations will discuss the following highlights: 1). Cycle life improvement by stimulation of Oxygen cycle 2). Dynamic charge acceptance improvement 3). Enhanced carbons and corrosion resistance 4). Advantages of enhanced carbons in terms capacity and rechargebility caused by sulphation and/or low SOC usage.

11:05 The 2nd Gen UltraBattery for Advanced 14-V hybrids
Jun Furukawa, Ph.D., Senior Fellow, The Furukawa Battery Co., Ltd.
The UltraBattery comprises a capacitor integrated with lead-acid cell. The 2nd Gen UltraBattery was developed for the newest 14-V hybrids equipped with integrated starter-generator (ISG) for power-assist and enhanced regeneration function. The advantages of the 2nd Gen UltraBattery for 14-V hybrid vehicles will be discussed.
11:25 Dynamic Charge Acceptance (DCA) to Improve the Real World Emission Performance of Micro Hybrid Vehicles
Stewart McKenzie, CEO, ArcActive
Car companies want high and sustained Dynamic Charge Acceptance (DCA) to improve the Real World Emission performance of Micro Hybrid vehicles. However, the DCA of batteries that meet typical Water Consumption requirements remain low, and batteries with high carbon loadings for better DCA typically suffer from unacceptably high Water Consumption. ArcActive has developed a Carbon Fibre based negative electrode, which displays high and sustained DCA but with low Water Consumption. ArcActive will share the latest battery level data on a variety of performance attributes.
11:45 There Is a Lot of Life Left in Lead – Overview on Automotive Battery Market Trends, Battery Field Experience & Lifetime and Future Development Potential of Start-Stop Batteries
Christian Rosenkranz, Ph.D., Vice President, Engineering & Product Development EMEA, Johnson Controls Autobatterien GmbH
Jörn Albers, Ph.D., Systems and Simulation Engineer, Johnson Controls Autobatterien GmbH
The focus on automotive emission reductions creates an opportunity for a growing diversity of electrification versions of the vehicle power train. This paper will give an overview of the global power trains electrification trends and focus on the fastest growing segment, the global start-stop market. An outlook will be given, how the increasing requirements of future start-stop vehicles will drive the performance of the next generation of start-stop batteries and combinations of multiple energy storage solutions.
12:05 Production Quality of Advanced LABs – Fulfilling the Zero Failure Approach
Andreas O. Stoermer, General Manager QMT Alternative Powertrains, BMW Group
How to proof good quality without testing the battery? This presentation will cover design quality: product design (D-FMEA), “house of quality” (QFD), design to manufacture, production quality: process design (P-FMEA), QFD, design to quality, use of process simulation by finite element method (e.g.), as well as process stability, online-spc, kpis, 0-rework approach, traceability and process interlock.
12:25 Lead-Acid Batteries for Future Automobiles
Juergen Garche, Ph.D., Senior Professor, Ulm University
The main functions of micro-hybrid cars as start–stop, brake-energy recuperation and propulsion assist can be fulfilled by advanced lead-acid batteries (EFB, AGM). But the Li-ion battery technology could be, in the long run, a serious competitor. To maintain its leading market position the LAB must lower costs and weight as well as increase lifetime and dynamic charge acceptance. This required, however, a stronger R&D commitment of the LAB industry.

Satoshi Inagaki, Global Technical Headquarters, Automotive Battery Technical Department, GS Yuasa International Ltd.
This Our New 5th generation enhanced flooded lead-acid battery technology for Stop-and-Start vehicles has been developed. According to our investigation on actual battery-failure modes in Japan, the major failure mode was sulfation i.e. accumulation and crystal growth of lead sulfate. Therefore, we aimed to prevent it for further improvement of the durability and reliability in the market, with new carbon technology and optimized additives in negative electrodes. The effectiveness was confirmed by accelerated battery test and field test.
