Abstract
The deployment of new-type infrastructure construction is accelerating.As a typical example of the new energy industry,electric vehicles and their charging piles have become important focus.As an electric energy measuring instrument,the accurate measurement of charging piles can ensure the fairness and impartiality of electricity trading,effectively support the high-quality development of the national economy and society,and fully meet the people's urgent needs for low-carbon and green travel.This paper analyzes the energy calculation principles and key technologies of electric vehicle charging piles,points out the problems in energy measurement of electric vehicle charging piles,and proposes corresponding solutions,such as using high-precision sensors,optimizing signal conditioning circuits,and improving line connections.By implementing these improvement measures,the accuracy,safety,and reliability of energy measurement of electric vehicle charging piles can be effectively improved,better serving the electric vehicle users and charging pile operators.关键词
