The first generation of Li-ion battery systems, which have already been introduced into series production, are used as high-voltage batteries in hybrid, plug-in hybrid and electric vehicles. These battery systems have proven in the field that Li-ion batteries can meet the high demands placed on safety and electrical performance in automotive applications. Very different cell housing technologies are currently used in Li-ion battery systems, whereby a basic distinction is made between so-called pouch cells and hardcase cells. The housing of pouch cells consists of a composite film, while hardcase cells have a metal housing with a cylindrical or prismatic shape.

The presentation will provide a detailed analysis of the cell technologies available today with regard to the achievable energy density, costs and other key performance indicators (KPIs) such as performance and service life. Among others, the standardized cell formats PHEV1 and 2, BEV1 and 2, the 18650 format known from the consumer sector and various pouch formats will be considered and market statistics will be prepared. Based on the current market situation and the state of the art, Bosch's market forecast for the years 2020ff is presented and the market targets for the most important KPIs - including the price in EUR/kWh and energy density in Wh/l - are discussed and mirrored against the technologies available today.

It will also look at how the requirements for cell and module mechanics will change and how these mechanics will continue to develop. The current scientific status of so-called post-lithium-ion technologies (PLIT) will be discussed. Post-lithium-ion batteries promise not only a further increase in energy density, but above all a reduction in the manufacturing costs of battery systems for automotive applications. The presentation will discuss how and when the switch from LIT to PLIT could take place.

Dr. Joachim Fetzer studied electrical engineering at the University of Stuttgart and received his doctorate in 1995 in the field of "Numerical and analytical electromagnetic field theory". From 1989 to 1998, he worked as a research assistant at the Institute for Theory of Electrical Engineering at the University of Stuttgart. In 1998, he moved to Robert Bosch GmbH, where he worked as group leader, software and function development in the K9 division. In 2001 he moved to Vector Informatik GmbH, first as Head of the Consulting Department and then as Managing Director of Vector Consulting GmbH. At the end of 2004, he returned to Robert Bosch GmbH, where he was responsible for hardware platform development for engine control units as department head until 2007. From 2007 to 2008, he headed the battery project house and was then responsible for engineering, quality management and corporate planning as one of the two managing directors of SB LiMotive Co Ltd, the joint venture between Samsung SDI and Robert Bosch GmbH, until 2012. Since September 2012, he has been a member of the Divisional Board of Management Gasoline Systems of Robert Bosch GmbH with responsibility for the product area of electric vehicle and hybrid technology as well as for the electrification of the powertrain.
