Abstract

In this paper, the active electric energy value of the charging pile and its change time scale are obtained through the image recognition algorithm, and the low-pass filter algorithm is used to filter out the time scale jitter. By calculating the active electric energy value (Ex) of the charging pile in the time scale interval and the standard electric energy value (Eb) in the same interval, the active electric energy error is calculated according to the electric energy comparison method. Compared with the traditional energy comparison method, the verification time is related to the minimum quantitative value of active electric energy, The verification time of this method is only related to the jitter of time scale and the quantization error of camera, which can greatly improve the verification efficiency of low-power charging pile.
