Research on Intelligent Distribution Method of Charging Power Based on Charging Pile
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.
