10:40 “Citius, Altius, Fortius” – Progress of Automotive Battery Systems at General Motors

Roland Matthé, GM Technical Fellow Global Battery Systems – Manager Electrification Architecture, Adam Opel AG

The Olympic motto “Citius, Altius, Fortius” can also be applied to automotive Battery Systems which are challenged by several, sometimes contradicting, requirements. The progress is driven by the need of long EV range (Altius = Higher or Further), good acceleration and fast recharge (Citius = Faster), and the need for long life under severe climate and usage conditions (Fortius = Stronger). And above all, is the need for low cost to make battery systems competitive in the automotive market where they compete with other energy storage systems like gasoline, diesel, and natural gas. The progress of battery systems during the last years is impressive and the presentation shows how General Motors battery systems for electric vehicles have improved from Gen 1 (e.g Opel Ampera, Chevy Spark EV) to Gen 2 (e.g Chevy VOLT 2 and Bolt, Opel Ampera-e). The potential areas for further progress will be outlined to indicate required areas of innovation.

CLOSING PLENARY SESSION: Battery Charging, Grid Integration, and Logistics

14:05 Chairperson’s Remarks

Jan Fritz Rettberg, Ph.D., Head of E-Mobility, ie³ Institute of Energy Systems, Energy Efficiency and Energy Economics, TU Dortmund University

14:10 The Path to Fast Charging--How to Solve the Drawback of Charging Times

Michael Keller, Senior Manager, Energy Functions, Member Executive Board – CharIN, Volkswagen AG

CharIN's goal is to improve charging and find solutions to overcome the three main drawbacks of current charging technologies: 1) Charging time for long distance stops, 2) Incompatible charging infrastructure, and 3) Grid performance requirements. Therefore CharIN suggests standardizations with a charging power of up to 350 kW to reduce charging time for long distance stops. By setting a worldwide standard with over ten OEM and several tier 1 suppliers being involved, CharIN guarantees long term security for investors and full up- and downward compatibility for all EV users. In combination with the high charging power the return on investment will increase.

14:30 Providing DC Charging Infrastructure and Implications for the Power Grid

Jan Fritz Rettberg, Ph.D., Head of E-Mobility, ie³ Institute of Energy Systems, Energy Efficiency and Energy Economics, TU Dortmund University

Extensive provision of fast-charging infrastructure will challenge power grids. Especially when it comes to charging processes with up to 350 KW and higher for high-performance batteries in next generation e-cars, e-busses or e-trucks. Nevertheless, it is mandatory to provide these charging infrastructures with electricity from renewable sources. Technological solutions will appear that enable grid-friendly fast-charging processes by using generation flexibilities and additional storage. Therefore, possible effects of DC fast-charging infrastructure like peak load, circuit feedback or grid expansion should be discussed in the search for locations.

14:50 Lithium Batteries – Important Tests (UN38.3, New Package Standards) & Safety Check Sheets

Sebastian Spies, Ph.D., Safety Advisor Dangerous Goods, Daimler AG

No matter what your job is in the battery business, somehow you will have come across the challenge of transporting lithium batteries (a dangerous good) from one place to another, e.g. to perform tests drives on international or national test tracks, for their presentation at motor shows, or to perform abuse tests at test institutes, etc. The presentation will give an overview of all important aspects regarding the transport of automotive size Lithium-Ion Batteries, including: examples of the vast majority of large Lithium-Ion Batteries present in the automotive industry (Orchestra of Lithium Ion Batteries at Daimler), international regulations in road, sea and air transport (including ADR, IMDG-Code, ICAOTI/IATA-DGR and 49 CFR), transport testing requirements (e.g. 2.9.4 UN Recommendations and 38.3 UN Manual of Tests and Criteria), assessment reports for risk determination before transport (examples of check sheets), prototype and tested type (serial) batteries, potentially damaged, defective and unsafe batteries, packaging, marking, labelling, and documentation (examples of packaging in all kinds of performance levels). 

15:10 Refreshment Break

15:25 Current Processes for Lithium Battery Recycling and Research Needs for Increased Efficiency

Bernd Friedrich, Ph.D., Director, IME Institute for Process Metallurgy and Metal Recycling, RWTH Aachen

We intend to present and compare chemical (<200°C) and metallurgical (>300°C) processes being developed up to now for Lithium Battery Recycling with respect to efficiency, environmental footprint and scalability. A special focus will be given to robustness against sorting failures in the feed, to the potential use for future electrode systems as well as to the recovery potential for Lithium and other economy-strategic metals. A discussion about the identification of optima between mechanical pre-processing and a minimum waste metallurgy demand will be made. Finally research needs will be addressed.

15:45 Trash to Fresh – Real Recycling of Lithium-Ion Batteries

Christian Hanisch, CEO, Lion Engineering GmbH

Don't trash - Refresh! There is still some homework to do in recycling of lithium-ion batteries - from EVs and others and this presentation will contribute to this discussion. It is possible to recycle lithium-ion batteries: resource-saving, environmentally friendly, and even economically feasible - with a tailor-made process for lithium-ion batteries. Such a combination of steps enables the recovery of a mass fraction of 75% and more on a material recycling basis from lithium-ion batteries. This is supposed to be much better than state of the art. Combining different process steps like discharging, dismantling, shredding, sifting, and air-jet separation, really good recycling yields and purities can be obtained. Thinking further, battery manufacturers will use such recycled materials very soon. A modified and simplified process works to directly recycle scraps from the production of lithium-ion batteries - in order to protect both: the environment and the stakeholder's money.
