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.
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.
Charging pile energy storage system can improve the relationship between power supply and demand. Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
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.
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. During the operation of the charging pile, the overall current is half-wave symmetrical, with only odd harmonics and no even harmonics.
