Abstract

Abstract: With the current rapid development trend of electric vehicles， aiming at the shortcomings of operation and maintenance of charging stations， a method for developing the operation and maintenance strategy of electric vehicle charging stations in the electric internet of things is proposed. According to the equipment structure and operation characteristics of the charging station， the fault model of the key charging facilities is established； the extra time spent in the charging process is used as the risk index， the reliability analysis of the electric vehicle charging station is carried out， and the importance level of operation and maintenance of different stations is divided according to the risk value and the operation and maintenance plans is formulated. Taking an area of a city as an example， the real-time equipment failure model and the charging model of users are used to evaluate the reliability of each charging station and allocate the operation and maintenance time resources reasonably.

Key words: electric vehicle, ubiquitous power internet of things, operation and maintenance strategy, charging facilities, reliability assessment
