摘要
研究了一种充电桩充电功率智能分配方法,启动充电后,功率分配单元与电动汽车通信,获取充电电压、充电电流数据;根据车辆需求的充电电压值,计算各种功率等级模块可输出的最大充电电流值;根据车辆需求的充电电流值和各种功率等级模块可输出的最大充电电流值进行计算,计算出最优的模块组合,该组合满足充电功率浪费最少原则;调用相应模块给该电动汽车进行充电,充电过程中会实时根据充电需求的电压、电流进行计算,电压电流变化过程中实时调整模块分配结果,充分释放冗余的充电功率,用于其他车辆的充电需求.该研究可以提高充电功率的利用率和用户的充电体验,减少充电车位的数量要求,从而降低充电站的运营成本.
Abstract
In this paper,an intelligent power distribution method of charging pile is studied.After starting charging,the power distribution unit communicates with the electric vehicle to obtain charging voltage and charging current data.Ac-cording to the charging voltage value required by the vehicle,the maximum charging current value that can be output by various power level modules is calculated.According to the charging current value required by the vehicle and the maxi-mum charging current value that can be output by various power level modules,the optimal module combination is calcu-lated,and the combination meets the principle of least waste of charging power.Call the corresponding module to charge the electric vehicle;During the charging process,it will calculate in real time according to the voltage and current of the charging demand.In the process of voltage and current change,the module allocation result will be adjusted in real time to fully release the redundant charging power for the charging demand of other vehicles.This research can improve the utili-zation rate of charging power,the charging experience of users,and reduce the number of charging parking Spaces,thus reducing the operating cost of charging stations.
