In the scientiﬁc literature, it has been a common assumption that electric vehicles (EVs) draw a constant current during the whole charging session. In reality, EV charging proﬁles are not linear, and the non-linearities have recently gained more attention. However, a thorough analysis of the inﬂuences of different charging proﬁle modelling methods is not yet carried out. This paper aims to ﬁll this gap by comparing experimental measurements of four commercial EVs and results of a developed simulation model that considers different charging proﬁle modelling methods. According to the results, the use of linear charging proﬁles may lead to notable modelling inaccuracies (error > 30%) whereas the use of measurement-based non-linear charging proﬁle models yields relatively accurate results (error mostly ≤3.5%). The results also demonstrate that the use of a simple, but justiﬁed, bilinear charging proﬁle model is likely to be sufﬁciently accurate in most scenarios.
