Resumen
"Reductions of fuel consumption and gas emissions count among the main advantages
of hybrid electric vehicles (HEV). It is well known that the level of hybridisation has a large
influence on the fuel consumption, the manufacturing cost and the battery lifetime. Therefore, a
proper selection of the size of components could be the result of a trade-off between them. This
paper provides models and a methodology to address the sizing of components of a HEV.
Specifically the work is focused on the series architecture with internal combustion engine and
battery. The sizing criteria are oriented to reduce the operating costs, in which are included the
fuel consumption and the battery-life consumption. Finally, the methodology proposed is applied
in a case study. It corresponds to a real hybrid electric bus operating under urban driving
conditions. Simulation results show that the best solutions are obtained by oversizing the battery
with respect to power requirements."
