Application Track 1

xEV Battery Technology, Application, & Market

31 January – 1 February 2018 | Congress Centrum Mainz | Mainz, Germany


No longer able to meet the tightening government emission regulations with conventional diesel and gasoline engines, automakers have accelerated the development of their xEV offerings to meet the more stringent upcoming regulations. Without clarity regarding the customers’ interest in these vehicles, developers are spreading their bets on multiple architectures—mild and strong hybrids, plug-in hybrids, battery and fuel-cell electric vehicles (with various driving ranges)—striving to meet the regulations at a cost they can pass to their customers. Consequently, while the expanding xEV market is alluring, the supply chain—particularly the battery suppliers—is under strong pressure to enhance performance, reduce pricing, and help automakers to improve the vehicles’ value proposition and achieve profitability.

The wide range of energy-storage requirements for the many types of xEV architectures creates opportunities for multiple cell chemistries, and cell and pack designs. In this symposium, i) industry observers will discuss market drivers and trends, ii) xEV and xEV battery developers will discuss the chosen battery designs and present performance data for existing vehicles, iii) automakers will present vehicle development and energy-storage requirements for future micro, mild, and strong hybrid vehicles, as well as for PHEVS and EVs, and iv) energy-storage developers will present the latest achievements in meeting the requirements of the various xEV architectures, including performance and life.

Onur Colhan, Developer 48V Battery Systems, Daimler AG

Daimler´s green strategy is based on fuel-cell technology and xEVs (48V Hybrids, Plug-in Hybrids and electric vehicles). It is a promise to find green, better, effective and cost optimized solutions to achieve the CO2 commitments in the fleet and to reduce emissions. The 48V technology is the best compromise between consumption and emissions towards a conventional drivetrain and the costs compared with other solutions like Hybrid & Plug-In systems. Furthermore due to the increasing electrification in upper-size class of cars, like S- or E-class, with future autonomous driving functions, more electric energy is needed upside the 12V-supply system on board. This presentation will discuss the new 48V system and its most crucial part, the 48V battery. 

14:40 Is a 12V Battery Needed on xEVs?

Fabian Fogelberg, HW Responsible 48 V Li-Ion Battery, Volvo Car Corporation

17:10 Progress of Toshiba SCiBTM with LTO Anode for Automotive Applications

Koji Ishiwa, Senior Manager, Automotive Systems Division, Toshiba Infrastructure Systems & Solutions Corporation

The role of the Lithium-Ion Battery (LIB) is expanding not only as a highly reliable power source in EVs and PHEVs, but also in low-voltage HEVs and conventional vehicles. However, current LIBs still have several challenges such as safety or life. As a solution, Toshiba adopted LTO anode technology, which has excellent performance such as safety and long life, since 2008. This presentation will cover updated information about SCiBTM and its direction of development for automotive applications.

17:30 High Durability of LTO/NCM Battery for 14 V System at 80°C

Keigo Hoshina, PhD, Specialist, Battery Development,Toshiba Infrastructure Systems & Solutions Corp

Low voltage system such as 12 V and 14 V battery is required thermal stability because the battery pack is put under high temperature environment in a car. LTO-based lithium ion battery has high temperature durability since the decomposition of liquid electrolyte unlikely occur at the working potential of LTO at around 1.55 V vs. Li /Li[+]. Furthermore, LTO-based battery shows excellent charge acceptance performance due to no lithium plating at quick charging. Therefore, LTO-based battery combined with 4 V-class cathode is suitable for 12 V and 14 V system. We reported that improvement of high temperature durability of LTO-based battery by using polyacrylonitrile (PAN) binder. It has been reported that conventional PVdF binder was deteriorated at high temperature of 80 ?C. We attempted to improve the high temperature durability of LTO-based battery by using a thermally stable polymer as a binder. LTO-based batteries are degraded due to the deterioration of cathodes. Therefore, it is effective that a thermally stable polymer is applied to a binder of the cathode. Li-ion battery with LTO anode was constructed with NCM cathode. PAN was applied to a binder of the NCM cathode. The LTO/NCM cell showed a high capacity retention of 94.2 % after 10 C cycling between 20-80%SOC under a high temperature condition of 80°C for 3000 hours which correspond to 11500 cycles. High temperature storage test was also carried out. The recovery capacity of the LTO/NCM cell stored at 100 %SOC at 80°C for 3000 hours were kept high of 96.2 %. Moreover, gas generation was negligible during 80°C operation. These results exhibited the LTO/NCM cell using PAN binder excellent high temperature durability. It is considered that PAN binder suppressed the decomposition of liquid electrolyte at the surface of the NCM cathode and the degradation of the NCM particle surface. LTO-based battery has outstanding high temperature performance and enables the battery pack to reduce the cooling system. The battery pack with LTO-based cells is suitable for low voltage systems.

BATTERIES FOR PHEVs AND EVs

9:00 Chairperson’s Opening Remarks

Roland Matthé, Technical Fellow Battery System & Manager Electrification Architecture, Opel Automobile GmbH

9:05 Cell and Module Strategy for Low-Cost EV Powertrains

Thomas Soczka-Guth, Ph.D., Team Leader Research Li-Ion Cell and Battery, Daimler AG

The different aspects of battery design and layout, such as cell design, cooling concepts, safety measures and battery housing are of great importance for the overall functionality of the battery system and require further optimization. However, all technical solutions known far represent small incremental steps in improving the battery performance, and these steps only marginally contribute to a further cost optimization. A major breakthrough in the technology could be only achieved with more drastic changes in the battery design concept. But of course safety, longevity, durability, performance and energy densities aspects provide some hurdles and barriers for new battery concepts and still strongly influence the trade-off of battery vehicle integration. In this presentation an overview on some different known battery integration concepts for different vehicle applications will be given – but new developments in more or less “classical” lithium ion cells might change the basic set of properties in such way that path for new battery integration concepts might be open in the near future.

9:25 EV Battery Technology and Charging Strategies - An Optimization Approach

Roland Matthé, Technical Fellow Battery System & Manager Electrification Architecture, Opel Automobile GmbH

To increase the market success of electric vehicles, the EV range is increased, using large lithium-ion batteries, and short recharge time is needed. The increase in charge power has an impact on battery system design, battery cell design, and chemistry. We will study the challenges of optimizing electric vehicles for long range, short charging time, and low cost, focusing on battery technology. Customer requirements, battery technology, and infrastructure effects should be balanced to make BEVs commercially successful.

9:45 Seven Technical Challenges of the Battery for New-Generation EVs

Gwennaëlle Pascaly, Battery Technology Development Group Leader, Renault

During the last years, Renault battery group was focused in upgrading their batteries to increase the energy density with the introduction of the longer driving range version of ZOE, Kangoo and SM3 in 2017. Now, the environment of the next generation EVs is evolving. EVs will belong to a global ecosystem which imply additional functions and give new constraints on battery design. In parallel, product targets become more and more challenging and the arrival of new regulations also bring new challenges to overcome. The purpose of this presentation is to share 7 technical challenges of the battery for the next generation EVs.

10:05 Battery Pack Designs for Modern (PH)EV Architectures

Christoph Fehrenbacher, Managing Director Europe, A123 Systems

As battery prices continue to decline, next-generation plug-in vehicles will be “born electric”, having been designed for electric drivetrains and the major electrified components having been packaged in the vehicle design from the start. The high-voltage battery will often be under floor. This drives a low-height, flat-pack battery design, which presents opportunities for module standardization across vehicle programs. We will discuss battery-design trends for next-generation plug-ins, corresponding module and cell requirements, and present a case study based on A123’s high-voltage module portfolio.

10:25 Coffee Break with Exhibit & Poster Viewing (Sponsorship Opportunity Available)

11:10 Progress with EV Battery Cost and Performance: How Far and How Fast?

Menahem Anderman, Ph.D., President, Total Battery Consulting, Inc.

The question proposed in the title is key to the proliferation of battery-powered electric vehicles. In this presentation, we will discuss i) the current status and anticipated pace of advances in the development of Li-ion batteries with higher performance and lower cost, ii) how close alternative battery chemistries are to supersede Li-ion in EV applications, and iii) the implications of both points above for the expansion of the EV market.

11:30 Challenges, Risks, and Opportunities for a Rapid Expansion of xEV Batteries

Sachiya Inagaki, Industrial Technology Unit, Yano Research Institute, Ltd.

It is expected that the xEV market will grow faster and larger than expected thanks to severe regulations on vehicles emissions. But, can we really expect such high expanding of this market? Can we totally rely on the governmental policies for growing this market? I would like to make some remarks on how we should see this market and how we should make it grow in a healthy way.

11:50 Enhancing Mileage, Lifetime and Safety by Predictive BMS Operation Strategy

Andreas Braun, Ph.D., Project Manager Battery, Engineering Center Ingolstadt, AVL Deutschland GmbH

BMS operation strategies today use static limits for derating or cooling. A predictive operation strategy can allow to make these limits dynamic. Depending on the driving situation and the forthcoming route topology an algorithm can maximize usability of the battery while driving. At the same time durability and safety can be enhanced. The approach makes use of navigation data and GPS (e-horizon), environment sensor information (ADAS) and intelligent learning algorithms to determine upcoming route topology and driving behavior.

BATTERY RELIABILITY AND DURABILITY IN xEV APPLICATIONS

13:55 Chairperson’s Remarks

Arnold Lamm, Ph.D., Project Leader EDrive 2025, Daimler AG

14:00 Ageing of Batteries: Deterioration Mechanisms of Cell Chemistries

Andreas Hintennach, Ph.D., Group Research, Mercedes-Benz, Daimler AG

Novel and sustainable electroactive materials can help to increase safety as well as efficiency of lithium-ion and post-lithium ion batteries. While on the one hand high energy density is required, the aspect of lifetime got more important and can be supported by e.g. solid-state electrolytes.

14:20 Inhomogeneities in Lithium-Ion Batteries

Andreas Jossen, Ph.D., Professor, Electrical Engineering and Information Technology, Technical University Munich (TUM)

Increasing the electrode thickness, reducing the porosity, increasing the specific capacity of the active material, and increasing the electrode size are methods to increase the energy density. However, most of these design parameters result in a more inhomogeneous operation and aging. Measurement methods with special designed multi-tab and multi-layer cells are presented and compared with simulation results. Additionally the inhomogeneous state of aged cells is shown by optical and XRD analysis. Especially in cells with flat discharge curves, reversible effects, for example resulting in capacity recovery, are observed.

14:40 Advanced Battery Aging Analyses Based on High Precision Coulometry

Peter Keil, Ph.D., Research Associate/Founder, Institute for Electrical Energy Storage Technology, Technical University Munich (TUM)

The presentation will show the identification of typical side reactions causing battery degradation and demonstrate how HPC can accelerate the development process of optimized operational strategies, e.g., for fast charging or avoiding battery damage when operating at low temperatures.

15:00 Improving the Lifetime of Li-Ion Batteries by Understanding Their Degradation Mechanisms

Emilie Bekaert, Ph.D., Line Manager, Post Mortem, CIC Energigune

The development of LIB has been accompanied by technological failures, ranging from premature end of life to more concerning safety hazards such as explosions. In order to predict the behaviour of new technologies prior to their commercialization, it is necessary to study the degradation mechanisms occurring in a specific system via aging of the cells. In this talk, we will discuss the effect of highly demanding condition of operation which can lead to degradation of the pristine cell and participate in its failure.

15:55 Legal Aspects of High-Voltage Battery Safety

Juergen Wilhelmy, Product Safety HV Battery, Audi AG

High-voltage Li-ion battery technology is comparatively new in the automotive industry and field experience covering the whole vehicle life-cycle outside of controlled conditions is limited. Accidents were reported, and high-voltage Li-ion batteries also present risks hitherto unknown in the industry, which has increased the manufacturer’s responsibility in relation to customers. What additional requirements must be met by car manufacturers and their suppliers? We discuss product liability in relation to power-train high-voltage battery, and examine the boundaries between functional safety, technical compliance, and product safety.

16:15 The Low Emission Mobility Package and Implications for the Battery Market in the EU
