“…The most common batteries used in the hybrid automotive industry are the Nimh batteries [1-3], while li-ion batteries have seen a great technological advance in electric vehicles. Numerous studies pointed out the advantages deriving from a combined use of li-ion batteries and supercapacitor on medium size cars [8][9][10] and on urban buses [6,11]. The charge-discharge efficiency of the storage system differs from one technology to another and it depends on the working conditions (mainly current and state of charge, SOC); this is the reason why different values are available in the technical literature even for the same storage type.…”

hybrid vehicles have experienced a great boom in recent years thanks to the increasing spread of 'parallel' architectures, often realized by a planetary gear train (hybrid Synergy Drive).at the same time, an enhancement of electrical and electronic components has been experienced; these improvements especially concern reliability and efficiency. Particularly, the possibility of using supercapacitors with increasing storage performances makes possible to manage higher power flows together with a superior efficiency. These innovations may challenge the architecture used nowadays on medium size cars.The hybrid series architecture, which allows the optimal management of the combustion engine, has been disadvantaged until now by the electric powertrain efficiency.In the current scenario, this architecture could benefit from the above-mentioned technology, becoming a competitive alternative to the actual powertrain configurations. The aim of this article is the efficiency analysis, in order to evaluate the operational energy efficiency achievable thanks to this configuration. This analysis will be carried out considering all the possible working conditions of the different powertrains.

“…From the technology perspective, several studies investigated battery's type for improving autonomy and performance of electric vehicles. Energy management strategies, focused on Li-Ion batteries [13] and Lithiumbatteries/Ultracapacitors [14], have been developed to evaluate the battery state of charge (SOC) in different conditions.…”
