Research on electric vehicle charging station based on solar energy

目前,电动汽车电池的续航能力有限是制约EV发展的重要因素,因此EV的充电方式成研发的重点。针对充电不确性情,提出一个潜在模型,重点研究将太阳能电力输送到电动汽车充电站的路线设计。本文使用MATLAB和SIMULINK设计一个包含电气控制系统的专用系统,用于改善电动汽车充电端与电池存储系统之间的相互作用,其中电气控制系统协助开发正确的占空比,以便DC/DC变换器稳和调节电压。所实现的电气控制系统在对电网的电能管理和减少EV的充电时间方面有着显著的效果。无论太阳能发电和负载的波动如何,该充电系统始终可以给负载端提供稳的电压。

The biggest worry of EV buyers is whether they can charge the car in time.Therefore,the charging method of EV has become the focus of research and development.At the same time,most traditional charging stations rely on the grid to supply energy.In the case of no electricity or power failure,electric vehicles will not be able to be charged.After comprehensive comparison,charging electric vehicles with wind or solar energy is generally optimistic.The installation of wind and solar systems and the dynamic increase of the grid connection of EV charging stations have brought uncertainty to the distribution network,such as voltage fluctuations,transients/harmonics.This paper aims to contribute and propose a potential model for the uncertainty scenario,focusing on the route design for delivering solar power to electric vehicle charging stations.This article uses MATLAB and SIMULINK to design a dedicated system that includes an electrical control system to improve the interaction between the charging terminal of the electric vehicle and the battery storage system.The electrical control system assists in the development of the correct duty cycle for DC/DC conversion.The device is stable and regulates the voltage.The implemented electrical control system has a significant effect on the power management of the grid and the reduction of the charging time of the EV.Regardless of the fluctuations in solar power and load,the charging system always provides a stable voltage to the load.
