The conventional electric energy measurement method for AC charging piles mainly uses PSO-PNN bird foraging behavior random optimization algorithm to obtain the optimal measurement solution,which is easily affected by changes in PNN network parameters,resulting in high deviations in electric energy measurement.Therefore,under harmonic conditions,it is necessary to design a new electric energy measurement method for AC charging piles.Under harmonic conditions,noise reduction was carried out on the electric energy measurement data of the charging station,and an AC charging station electric energy measurement device was designed,thus completing the electric energy measurement of the AC charging station.The experimental results show that the designed AC charging pile energy measurement method measures the charging pile current and voltage values with small differences from the actual values,proving that the designed AC charging pile energy measurement method has good measurement effect,accuracy,and certain application value.It has made a certain contribution to improving the reliability of AC charging pile energy measurement and extending its service life.
