- More and more electric vehicles have been used in China, and many charging station has been built in China. Due to the reactive power loss caused by charging devices, the method to measure the power consumed by charging device is critical for power company. Based on impact loads generated by electric vehicles to the grid in fast charging mode, this paper studies the energy measurement method of electric vehicle charging mode. Since each phase current of charging post imbalance, to prevent the sum of each phase current vector of charging posts over the protection current threshold and the charging post breaker misusing in power circuit, preventing leakage circuit breaker current imbalance system is designed. Finally, this paper studies the power consumption detection methods of electric vehicle charging posts. By comparing the fast Fourier transform and wavelet analysis algorithms, an electric energy measurement device of electric vehicle charging machine based on FFT and wavelet analysis are proposed. Combined with fast data processing functions of DSP, the device can quickly and accurately measures electric vehicles charging amounts under different charging modes.
