Future Vehicle Power Nets Enabling Further Electrification 2009-01-0522

The challenges of future power nets will lead to the limits of today’s conventional 12V power net, equipped in every series production vehicle. The four introduced limits are given by the peak power, the average power, the stored electrical energy and the stress of the storage. As a result, changes of active and passive components as well as extensions of the power net are presented if the higher requirements cannot be reached by improving the electrical energy management. Additionally electrified power trains will lead to even more diversification of future power nets. New standardization of architectures and voltage levels is strongly needed. Suggestions are made in the paper at hand.
