In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
When a charging pile is idle, the EV at the front of the queue goes to the charging pile to charge. The EV queueing model at the charging station is shown in Figure 9. For the EV that needs to be charged on the way, the travel time consists of two parts: the travel time on the road and the charging time.
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.
The results of the analyses show that the proposed method can not only save the time cost of EV users waiting for charging, but also effectively take into account the utilization rate of charging piles. References is not available for this document. Need Help?
A two-stage model has also been proposed to optimize EV charging and the selection of charging piles by effectively grouping the distribution pattern of EV charging demand and various types of EVs, and by minimizing the annual investment and electricity purchasing costs of charging piles [ 34 ].
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
