Offline optimization for components sizing and analysis of a plug-in hybrid urban microbus

An offline optimized energy management of a plug in series hybrid microbus is used for optimal component sizing and CO₂ versus cost analysis. Comparison between fixed-rate battery discharge management and a global trip optimization are first performed. Then a parametrical study on components sizing is presented and give some elements concerning the best compromise between fuel consumption and The generating group size. A short economic study shows that according to the battery price and lifetime, and other economical parameters, an optimal SOC cycling could be found.
