Currently, new energy vehicle charging piles are manual charging piles. Due to the fixed location of the charging piles and the limited length of the charging cables, manual charging piles can only provide charging services for the vehicles to be charged in the nearest two parking spaces at most.
Design of Energy Storage Charging Pile Equipment The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period.
In this paper, based on the cloud computing platform, the reasonable design of the electric vehicle charging pile can not only effectively solve various problems in the process of electric vehicle charging, but also enable the electric vehicle users to participate in the power management.
However, one charging pile can only provide charging services for one vehicle simultaneously, and there are uncertainties in the time that electric vehicles stay in the charging parking space and the required charging amount.
