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.
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.
On the one hand, the energy storage charging pile interacts with the battery management system through the CAN bus to manage the whole process of charging.
Once the EV charging piles are coupled to the power grid, due to the different convergence levels and charging behaviours of different electric vehicles, once connected, it will affect the voltage level of the power system. Due to the voltage dip, the reactive power of the power grid may increase.
Analyzing the effect of EV charging pile intervention on grid harmonics can better control variables and make governance measures to verify theoretical knowledge. When the EV charging pile is working, the impact of grid harmonics can be managed (Zhang et al., 2022), so that the electric vehicle industry can be well developed.
The promotion effect of direct-current charging piles on EV sales is twice that of alternating-current charging piles in the one-year simulation of our model. Increasing the number of EV charging piles has a significant impact on battery electric vehicle sales but not on plug-in hybrid electric vehicle sales. 1. Introduction
