“…• 42 volt system: A mature technology exists in power electronics, which is applicable to both commercial and the military applications as well, and is essential for the 42 volts dc system architecture [2][3][4][5]. Power electronics will be needed for the conversion of the variable-speed alternator voltage to a constant dc voltage.…”

Abstract-In the near future, a significant increase in electric power consumption in vehicles is expected. To limit the associated increase in fuel consumption and exhaust emissions, smart strategies for the generation, storage/retrieval, distribution, and consumption of electric power will be used. Inspired by the research on energy management for hybrid electric vehicles (HEVs), this paper presents an extensive study on controlling the vehicular electric power system to reduce the fuel use and emissions, by generating and storing electrical energy only at the most suitable moments. For this purpose, both off-line optimization methods using knowledge of the driving pattern and on-line implementable ones are developed and tested in a simulation environment. Results show a reduction in fuel use of 2%, even without a prediction of the driving cycle being used. Simultaneously, even larger reductions of the emissions are obtained. The strategies can also be applied to a mild HEV with an integrated starter alternator (ISA), without modifications, or to other types of HEVs with slight changes in the formulation.Index Terms-Energy management, fuel reduction, hybrid electric vehicles (HEVs), regenerative braking, vehicular electric power system.

“…To handle future power demands, the automobile industry has proposed a new 42V power net topology which should replace the traditional 14V power net from present vehicles (Kassakian et al, 2000;Nicastri and Huang, 2000). Although these advanced power nets will be able to meet tomorrow's power requirements, a problem that arises is how to control the power net, in order to reduce the fuel consumption of the vehicle.…”

In the near future, a significant increase in electric power consumption in vehicles will occur. To limit the associated increase in fuel consumption and exhaust emissions, smart strategies for the generation, storage/retrieval, distribution, and consumption of electric power will be used. This paper deals with an advanced power net with two storage devices: a lead-acid battery and a super capacitor, whose advantages can be combined. Two methods to control such a power net are presented: global optimization using full knowledge of the future driving pattern and an online implementable strategy doing without future knowledge. Both methods involve mixed integer optimization. The performance of the real-time strategy is close to the global optimum. c 2005 IFAC
