“…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.…”

“…a large spread of the series architecture has also taken place as it regards urban bus applications, together with studies supporting and evaluating the benefits deriving from this structure choice [4,5]; on the other hand, other studies analyse the effects of different types of storage systems [6]. Series architecture has not seen significant application on the medium size car so far.…”

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.

Abstract. The research concentrates on the modernisation issues of inefficient diesel-electric shunting locomotives, produced in the former Soviet Union. The existing diesel-generator unit, serving as an onboard power plant can be replaced by hybridised units, with an energy storage unit acting as a peaking power source for dynamic modes. By integrating an energy storage unit into the power plant, the locomotive traction drive becomes hybridised, consuming less fuel during transients and idling.

“…The increasing interest in sustainable mobility has led to the study and development of new hybrid architectures, which can be mainly divided in three main categories [1]: parallel [2][3][4][5][6], series/parallel (also known as power-split) [6][7][8][9][10][11][12][13][14], and series hybrid [15][16][17][18][19][20][21]. Passalacqua et al [22] proposed a new series architecture configuration for medium size cars, with a storage system based only on supercapacitors and they highlighted the benefits in terms of internal combustion engine (ICE) optimal working points.…”

Turbocompound Power Unit Modelling for a Supercapacitor-Based Series Hybrid Vehicle Application

In this paper, starting from the measurements available for a 2000 cm3 turbocharged diesel engine, an analytical model of the turbocharger is proposed and validated. The model is then used to extrapolate the efficiency of a power unit with a diesel engine combined with a turbocompound system. The obtained efficiency map is used to evaluate the fuel economy of a supercapacitor-based series hybrid vehicle equipped with the turbocompound power unit. The turbocompound model, in accordance with the studies available in the technical literature, shows that the advantages (in terms of efficiency increase) are significant at high loads. For this reason, turbocompound introduction allows a significant efficiency improvement in a series hybrid vehicle, where the engine always works at high-load. The fuel economy of the proposed vehicle is compared with other hybrid and conventional vehicle configurations.
