Abstract(s)
In response to environmental impacts and all the limitations caused by fossil fuels, we
have been witnessing in recent decades to the sharp development of hybrid electric
and electric vehicles, particularly in heavy-duty passenger vehicles. Its proliferation is
now widespread in virtually every major vehicle brand, reflecting operator confidence.
In order to further mitigate the use of fossil fuels, the trend is to increase supply in
100% electric versions. However, the evolution of recent years, both in manufacturers
commercial strategy of major brands and bodybuilders and in sales volume, seems
to indicate a new demand stage for this kind of vehicles, which are still making the
first steps in Portugal. However, high acquisition costs and limited autonomy are still
major obstacles to a faster proliferation of electrification in heavy vehicles. Its strengths
such as lower air and noise pollution, in addition to lower operating and maintenance
costs, led to a growing acquisition in the Portuguese vehicle market, where 16 new
heavy-duty passenger BEV have been sold this year. Real-world operational impacts
of these vehicles indicate a energy use between 0.91 and 1.65 kWh/km depending
on driving context. It has been also observed that operators are still adapting and not
always using the full battery capacity.
