摘要
电动车智能充电时,若不能及时控制电动车有序充电,会直接增加充电功率负荷,为缩减充电站充电功率负荷,提出基于峰谷差检测反馈的电动车智能有序充电控制系统。首先针对电动车智能有序充电分析结果明确电动车充电流程,构建电动车智能有序充电控制系统整体框架;基于建立的框架详细分析系统各个模块的功能,设计有序充电控制模块,用峰谷差方法计算电动车充电过程,获取电动车充电时的预测充电负荷值,并将其反馈给系统有序充电控制模块,辅助系统实现有序充电;最后设计各个软件程序使用流程,结合设计的硬件模块实现电动车智能有序充电控制。实验结果表明,使用该方法开展电动车智能有序充电控制,充电过程的有功功率负荷值与期望功率负荷值相接近,电流、电压输出结果稳定,控制效果较好。
During intelligent charging of electric vehicles,if the orderly charging of electric vehicles cannot be controlled in time,the charging power load will be directly increased.In order to reduce the charging power load of charging stations,an intelligent orderly charging control system for electric vehicles based on peak valley difference detection feedback is proposed.Firstly,the charging process of electric vehicles is clarified according to the analysis results of intelligent orderly charging of electric vehicles,and the overall framework of intelligent orderly charging control system of electric vehicles is constructed;Based on the established framework,the functions of each module of the system are analyzed in detail,and the orderly charging control module is designed.The peak valley difference method is used to calculate the charging process of electric vehicles,obtain the predicted charging load value when charging electric vehicles,and feed it back to the orderly charging control module of the system to assist the system to achieve orderly charging;Finally,the use flow of each software program is designed,and the intelligent and orderly charging control of electric vehicles is realized by combining the designed hardware modules.The experimental results show that the active power load value is close to the expected power load value during the charging process,the current and voltage output results are stable,and the control effect is good.
