Zusammenfassung

Future automotive applications will increasingly have electrified powertrains such as HEV, PHEV, REEV and BEV. One of the key elements of these powertrains will be the energy storage system or ‘Battery System’. Depending of the type of vehicle: sport, passenger, commercial, heavy duty or off road and its usage profile the battery
system will have to be optimised, either for power or energy content and sometimes a mixture of both. The battery system will also need to satisfy functionality, performance and safety over a long lifetime. Design and development of battery systems will have to address the above needs but will also need to provide a possibility for a modular design that can be used in various applications such as
HEV, PHEV, REEV and BEV and across entire vehicle segments in sport, passenger or commercial vehicle.

The aim of this paper is to present the design and development of innovative modular battery systems for use in the above mentioned applications for the sport, passenger cars and commercial vehicles. The system is optimised for each of the applications and vehicle segment through a holistic approach starting from the basic cell electrochemistry through module and pack engineering to battery management system implementation ultimately creating a fully operational battery system. The battery system is also scalable providing the optimum packaging space and use of common parts across applications.
