Summary

The progressive electrification of the power train for passenger cars currently brings a massive cost increase of the overall system itself. The additional cost result primarily due to the additional systems and components, such as battery, generator, electric motor, power electronics and the like causes, but is also increased due to the extended complexity in the control of these systems and their integration into the vehicle. Even in case of economies of scale in mass production for electric components maintaining well known power train technologies still remain substantial additional cost compared with non-electrified power trains. AVL's approach to cost reduction for comparable performance and fuel consumption target values with current production solutions is a radical and continuous integration of functions. The concept of functional integration critically scrutinizes and redefines existing interfaces, based on the established manufacturing and assembly sequences in mass production.
