To ensure sustainable individual mobility worldwide, despite the prospect of future limited crude oil resources, alternative powertrains based on hybrid technology and fuel-cell technology are becoming increasingly important. This need will be underlined by the regulations in Europe (ACEA CO2 Self-Commitment) and in the U.S. (ZEV regulation). There are three steps towards the 'Energy for the Future' at DaimlerChrysler: efficient cars based on improved internal combustion engines with or without hybridization, improved conventional and alternative fuels (e.g. biomass-to-liquid), and emissions-free vehicles with fuel-cell/battery drive. Additionally, improvements can be expected with respect to aerodynamics and (lightweight) body construction (see bionic concept car of DaimlerChrysler). The benefits of hybrid technology are reduced fuel consumption and emissions (increased driving range, stop/start functionality, recuperation, zero emissions when stationary), increased comfort (pure electrical driving, option of connecting to internal/external electrical loads), and increased performance (agility, continuous and smooth torque characteristics, and performance boost function). The definition of hybrid powertrains and examples of operation modes will be given in the presentation. By the end of 2003, DaimlerChrysler had delivered 30 Citaro fuel-cell buses containing fuel-cell systems as part of the European 'CUTE' program to ten European cities. The experience and the feedback since then have been extraordinarily positive. In particular, the lifetime results in the real-world operation at the customers have been highly satisfactory. Furthermore, in 2004/5, DaimlerChrysler delivered 60 F-Cell cars to customers in four different regions of the world: the U.S.A. (mainly California), Singapore, Japan, and Germany. Within these programs, the fuel-cell technologies are evaluated for their 'fitness for daily use.' In 2004, a Sprinter van was delivered to UPS for use in the U.S.A. The actual range achieved for the F-Cell-fleet is more than 5,000,000 km. The high-voltage battery (> 60 V) will play a dominant role for both the hybrid powertrain and the fuel cell powertrain. Indeed, NiMH-battery systems are currently in the existing market for hybrid cars and fuel-cell cars. Li-ion batteries are on the verge of industrialization for the automotive industry. The presentation will give an overview of these high-voltage batteries for alternative automotive applications, e.g. technology NiMH battery, technology Li-ion battery, experience F-Cell battery, next generation of high-voltage batteries.
