Study on Implementation Plan of Requirements for Charging Facilities International Standard Systems Comparison

Due to the increasing impact on the peak valley balance of the power grid, a large number of electric vehicles connected to the urban power grid for uncontrolled charging will increase the uncertainty risk of the urban power grid. Due to the change of energy flow from one-way charging to two-way charging and discharging, the two-way interaction of vehicle networking exposes the problems that electric vehicles cannot discharge to the power grid and the risk of uncertainty increases. Improving the charge and discharge detection system is the key to ensure the safe and reliable charge and discharge of vehicle pile networking system. However, the detection system of electric vehicle charging and discharging system is extremely imperfect, which affects the internationalization of Chinese products. In order to solve the problem of lack of international certification means in China's charge discharge inspection system, it is urgent to study the construction and implementation of conformity assessment system. By studying the consistency of standard system and the differences of key technologies at home and abroad, combined with the development direction of innovative charging facility products and detection technology, this paper puts forward future oriented international standard requirements. On this basis, based on the IEC conformity assessment framework, the effects of functional performance and operating environmental factors of charging facilities are analyzed, and the IEC charging facility conformity assessment parameter system is studied and proposed. At the same time, through the research on the quantification of parameter system and the formulation of supervision cycle, starting from the internal and external environment of charging facilities, this paper studies the contribution of various factors to the quantitative index and parameter system, and puts forward a quantitative index system. The evaluation index model of charging facilities is proposed Study the calculation and analysis strategy of quantitative indicators put forward the dynamic health evaluation method of charging facilities realize the reasonable establishment of certification supervision cycle and support China's participation in international conformity assessment.
