9:05 電動輸送機器に対応する電池の重要な問題への対応

Rachid Yazami, PhD, School of Materials Science & Engineering, Program Director, Energy Storage, Energy Research Institute, Nanyang Technological University, Singapore; Founding Director, KVI PTE, LTD

Lithium-ion batteries (LIB) are expected to play a major role in the future of electromobility owing to outstanding energy storage performances. Yet, several issues still need to be addressed to ensure a smooth mass-market acceptation and penetration. Among important issues are safety, long service life, and fast charging. At KVI, we have developed a thermodynamics-based technology, which proved to efficiently serve as a diagnosis tool to assess online LIB cell’s state of charge, state of health, and state of safety.

9:30 材料費が安く、安全性の高い高電圧電池管理システムの考え方

Jaehoon Park, Principal Engineer, Samsung SDI

General BMS description based on the difference between low-voltage (LV from below) & high-voltage (LV from below) BMS. The key features of HV BMS, in addition to the LV BMS feature, will be presented. Trade-off between safety and cost – generally speaking, high safety requirement is figured out to result in high material cost. However, it could be the opposite way, such that high safety requirement enforces to implement low cost BMS concept. The idea and justification will be presented.

9:55 強度の低いセルに起因する性能の限界に対応する予測ベースのリチウムイオンマルチセル電池管理の手法

Scott Trimboli, PhD, Associate Professor, Department of Electrical & Computer Engineering, College of Engineering & Applied Science, University of Colorado

Electric vehicle (EV) battery systems require careful and continuous management to ensure safe and reliable performance. This presentation describes a novel multi-cell control approach (in the context of an active-balancing architecture) that monitors individual cell behavior and acts to mitigate the limiting effect of the weakest cell on overall pack performance.

10:50 エネルギー密度の高いリチウムイオン電池の充電状態チェック機能としてのオンボード診断出力減衰監視

Pierrot Sassou Attidekou, PhD, Faraday Institution Research Fellow, School of Engineering, Newcastle University

Both energy and power density of Li-ion batteries degrade with aging and hence, impede their health. A realistic, accelerated aging driving cycling profile has been designed and applied to Kokam-type batteries. An in situ method was utilized to estimate the internal resistance. The resistance growth was monitored and modelled at three different voltage regions. The model shows that the batteries degrade less around the nominal voltage when compared to other voltage regions.

11:15 個々のセルの特性と電池パックの性能の間にあるギャップを埋めるための取り組み

Hans Harjung, PhD, CEO & Founder, e-moove GmbH

Today’s features of an individual automotive battery cell would enable EVs to run more than a million kilometers (3-5000 cycles of 3-500 km). But real-life-data shows a different and quite heterogeneous picture. The difference is based on the heterogeneous aging of the individual cells. Today’s balancing strategies cannot get out the full potential of the battery. A completely new approach is needed: effective control of each individual cell by its health and aging parameters.

14:20 EVの予測性能を示すラゴーンプロット

Brian Barnett, PhD, President, Battery Perspectives LLC

Power-Energy curves, now widely known as “Ragone Plots” were first employed in 1967 by David Ragone during US government hearings into air pollution and the prospects for electric vehicles. The first plots illustrated the status of batteries circa 1965, clearly demonstrating the challenges batteries faced to deliver both the required range and power for EVs. With EVs now a growing reality, much has changed. This talk uses Ragone plots to illustrate how battery technology changed and still can improve.

14:45 電池システムの性能向上とxEV業界のトレンド分析

Kevin Konecky, Battery Systems Consultant, Total Battery Consulting, Inc.

Battery systems are complex systems with the battery cell as the core technology of the system, but then integrated with multiple subsystems, including mechanical, thermal, and battery management systems (BMS). This presentation will look into the different subsystems that contribute to the overall battery system performance and opportunities for improvement in next-generation battery systems. Industry trends will be evaluated to show how the xEV industry has progressed over the recent wave of electrification.

15:50 モジュールの熱構造シミュレーションに対応する均質化された円筒型電池モデル

Youngwon Hahn, PhD, Senior Industry Solution Manager, SIMULIA T&M Initiative, Dassault Systemes SIMULIA

In this talk, the methodology to build the numerical model for homogenized cylindrical battery cell model which can capture SOC-dependency and strain-rate dependency is presented. Some of the results in module-level structural and thermal simulation are also discussed.

16:15 低電圧xEVの応用分野の分析とSCiB™による電池設計の最適化

Masahiro Sekino, Chief Specialist, Battery System Application Engineering Department, Toshiba Corporation

Low-voltage hybrid vehicles (LV-xEV) with lithium-ion battery will prevail to be mainstream in the near future. On the other hand, a difference in system voltage (12V through 48V) will be evident depending on region (Japan and Europe). In this presentation, the energy and power requirement of various components for a LV-xEV system will be analyzed in the viewpoints of fuel efficiency and CO2 emission. Furthermore, optimized battery design with SCiB will be proposed.

16:40 リチウムイオン電池パックの劣化の検出、診断、制御

Gregory Offer, PhD, Senior Lecturer, Mechanical Engineering, Imperial College London

The latest work of the electrochemical science & engineering group at Imperial College London on understanding how thermal management affects performance and degradation, and how thermal techniques can be used to detect and diagnose path-dependent degradation will be presented. A comparison of surface cooling vs. tab cooling shows that surface cooling limits useable capacity considerably and causes accelerated degradation.

9:30 電池パックの設計に役立つセルの安全性試験

Johannes Roessner, Global Focus Segment Manager NEV, Transportation Testing, TÜV SÜD

Safety testing of cells does not only give insights into the behavior of the cell, but also helps to draw conclusions about the design of the module and pack. This helps to speed up development time and gain results more efficiently.

9:55 リチウムイオン電池システムのセル破裂と熱暴走の数値予測と対策の評価

Daniele Suzzi, PhD, Lead Engineer HV-Battery & EE Thermal, CFD-Simulation, Engineering and Technology Powertrain Systems, AVL LIST GmbH

While the failure of a single cell leads to a rather limited hazard, the propagation to adjacent cells may release the whole energy stored in the battery pack, leading to severe conditions, such as fire and fierce explosions. These investigations are of significant relevance for developing strategies to prevent or postpone TR propagation, as well as to meet safety requirements for LIB modules in electric vehicles.

10:50 劣化したリチウムイオン電池の分析から得られた教訓

Mariyam Darma, Institute for Applied Material-Energy Storage System, Karlsruhe Institute of Technology

Tremendous works on post-mortem analysis have successfully revealed the most dominant mechanisms for battery degradation in correlation with the cycling and storage histories of the cells, such as charge rate, depth of discharge, operating voltage window, temperature, and state of charge. Interesting questions: How do relevant industries (automotive and battery) take benefit from the results? For battery second-life application: Can we use the current know-how to recommend a robust routine to predict the main degradation mode of batteries that have reached their end of life?

11:15 さまざまな条件で運用される固体高分子型燃料電池 (PEFC) の形態学的、科学的構造解析による総合的な劣化解析

Tsuyoshi Akiyama, Senior Research Chemist, Organic Analysis Laboratory, Toray Research Center

Degradation analysis of the respective sites (catalyst layer, electrolyte membrane, and wastewater) of polymer electrolyte fuel cell (PEFC) subjected to the start-stop cycle test and the load cycle test were performed by morphological structure analysis (X-ray CT, SEM, EPMA) and chemical structure analysis (GPC, IC, LC/MS, LC/CAD). As a result, the morphological and chemical structure changes were different between two type cycle tests.
