Electric vehicle charging infrastructure connected to a distribution network is a particular business expansion.The main factors affecting the schemes of electric vehicle charging infrastructure connected to a distribution network are analyzed.Considering power supply reliability，voltage quality of middle voltage distribution networks and the characteristics of energy storage of electric vehicles，a comprehensive analysis is made of several typical schemes of electric vehicle charging infrastructure connected to a distribution network，such as charging stations connected or adjacent to110kV substations as standby power，charging stations connected to the tie point in the looped distribution network as short-term standby power，charging stations parallel with the especially important load as emergency power.Advantages and disadvantages of these schemes are analyzed，and the scopes of possible applications are summarized.
