摘　　要：充电桩运行环境恶劣,长期使用线路容易发生老化、采样精度下降,导致实际输出电压偏低,提前进入了恒压充电阶段,导致车辆在这个阶段充电电流异常偏小,甚至直接没有电流输出,大大地影响了充电效率。本文深入探讨了末时段充电情况,详细地分析了当前存在的问题,根据问题提出了一系列智能化的解决方案,以预知风险、提升充电效率。The operating environment of the charging pile is poor,and the long-term use of the line is prone to aging and the sampling accuracy is reduced,which will make the actual output voltage of the charging pile low,and enter the constant voltage charging stage in advance,resulting in the abnormal small charging current of the vehicle at this stage,or even no current output directly,which greatly affects the charging efficiency.This paper deeply discusses the charging situation at the end of the period,analyzes the current problems in detail,and pro-poses a series of intelligent solutions according to the problems to predict the risks and improve the charging efficiency.
