Parameters selection of extended-range electric vehicle supplied with alternative fuel

Abstract

Abstract. In this paper modelling of extended-range electric vehicle powertrain. The model consists of sub-models of the investigated vehicle with its resistance forces, traction electric motor, range extender supplied with alternative fuel, and Li-Ion battery. Working point parameters of the range extender engine were defined to achieve low liquefied petroleum gas consumption. The model allowed to study possible parameters of vehicle range extender and battery size. The results show the higher influence of range extender power than battery energy capacity on the vehicle range. The defined range extender and battery parameters allow to significantly extend the vehicle range with low fuel consumption. This research provided ground for the further investigation of range extender control strategies.

Empirical Study on the Efficiency of an LPG-Supplied Range Extender for Electric Vehicles

“…The importance of providing adequate driving range to BEVs users has led to the development of extended range electric vehicles (EREVs), which combine an electric powertrain with an ICE [9,10] Despite their practicality, EREVs are not an ideal solution because the use of an onboard ICE to ensure sufficient range of the vehicle results in emission of pollutants. Recently, it has been proposed to limit this emission by supplying range extenders with alternative fuels [9,11,14,15]. While there are many gaseous and liquid fuels to consider [16], the use of liquified petroleum gas (LPG) and its renewable version, BioLPG, are considered as currently viable options [11,17,18].…”

While there are many gaseous and liquid fuels to consider [16], the use of liquified petroleum gas (LPG) and its renewable version, BioLPG, are considered as currently viable options [11,17,18]. They offer not only significant possibility to limit emission of harmful substances, but also good cost effectiveness over existing range extension technologies utilizing gasoline and diesel engines [11,19].…”

“…The empirical data collected has been adopted in the simulation of extended-range electric vehicle in a driving cycle, showing the potential of utilizing the results of this study.Energies 2019, 12, 3528 2 of 23 ( Figure 1). Their principle of operation is same as that of a standard BEVs, with the only difference being that an additional ICE acts as an on-board generator (range extender) to recharge the battery [11]. EREVs operate exclusively as BEVs when battery energy is available and have full performance in electric mode (e.g., top speed, acceleration capability) [12].…”

“…This is possible owing to EREV's electric propulsion system and battery sized in such a way that the ICE is not required for vehicle operation as long as battery energy is available [12]. It is therefore preferable to move the vehicle with the use of an electric motor only, i.e., in "zero emission" driving mode, but at the same time, the user is not afraid of running out of battery energy, and so called "range anxiety" (the term was introduced in the late 1990s [13]) is alleviated.Energies 2019, 12, x FOR PEER REVIEW 2 of 25 being that an additional ICE acts as an on-board generator (range extender) to recharge the battery [11].
