Abstract
Modern vehicles have faced a continuous rise in power demand over the last decade. It is neither possible to cover all energy needs reliably, nor to guarantee a successful cranking. Therefore new solutions are needed, such as energy management or the introduction of 42V-technology (mild hybrid). This dissertation discusses the design requirements of energy management systems (e.g. power-train dimensioning) and considers some interventions (e.g. reduction of power demand, motor idle speed lifting), as well as the associated consequences (battery state, consumer satisfaction). The dissertation contains an example of the energy management system, which is based on the battery- and alternator specific data. Different aspects are emphasised regarding the 42V-technology: impact of the energy management on the battery state, optimisation of the battery state of charge, support of the combustion engine by the electrical system when cranking and/or bringing up to speed, and recovery of the braking energy. The dissertation shows the methods for the validation of energy management systems, which are based on Matlab/Simulink simulations. Several battery-, alternator- and consumer models are shown. Finally a tool chain is presented, which allows the automation of simulation processes. (orig.)
