Energy Management Strategies for Vehicular Electric Power Systems

In the near future, a significant increase in electric

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),

electric power system to reduce the fuel use and emissions, by

show a reduction in fuel use of 2%, even without a prediction of the

of the emissions are obtained. The strategies can also be applied to
a mild HEV with an integrated starter alternator (ISA), without
