In order to measure and assess the energy efficiency level of DC charging pile,this paper has designed an energy efficiency measurement scheme for electric vehicle DC charging pile.This scheme can measure the power loss of each part during charging and the result can trace to the source by choosing appropriate measuring points and energy meters combining economy and veracity factors.Based on this scheme,a simulation is conducted for charging pile module and the actual DC charging pile is test in real-time to get the relevant waveform and electric data.The energy loss of charging pile can be calculated and analyzed according to the data.By contrasting the theoretical loss analysis results with simulation and the actual measuring results,the accuracy of energy efficiency measurement scheme can be examined,which provides the basis for energy conservation and loss reduction of electric charge.
