The survey showed that the majority of EV users prefer charging at home if the charging piles (CPs) are available [33]. Fig. 1 depicts a typical situation of a private EV employing home-based charging. This EV experiences an overnight charging at home so as to draw sufficient energy for the following journey.
DC charging piles have a higher charging voltage and shorter charging time than AC charging piles. DC charging piles can also largely solve the problem of EVs'' long charging times, which is a key barrier to EV adoption and something to which consumers pay considerable attention (Hidrue et al., 2011; Ma et al., 2019a ).
