Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention provides an electric vehicle charging navigation system based on edge computing, such as figure 1 As shown, including terminal layer, edge layer and cloud layer;

[0036] The terminal layer includes vehicle intelligent terminals and charging station sensors. When the user sends a charging request, the vehicle-mounted intelligent terminal transmits the remaining power, current location and driving speed of the electric vehicle to the nearby base station, and the charging station sensor transmits the real-time electricity price of the charging pile and the usage of each charging pile to the nearby distribution network in time The base station with the edge computing module realizes the data interaction between the base station, the vehicle intelligent terminal and the charging station sensor. Since navigation is a...

Abstract

The invention discloses an electric vehicle charging navigation system and a method based on edge calculation. The system comprises a terminal layer used for collecting data of a vehicle-mounted terminal and a charging station sensor, an edge layer used for charging navigation strategy operation, and a cloud layer used for selecting a base station with the most residual resource proportion to provide charging navigation service for a user. According to the method, the overall computing performance of the system is improved mainly by utilizing edge calculation, and the flow is loaded by more nodes of the edge calculation, so that the data transmission speed is higher, is closer to terminal equipment, the transmission is safer, and the data processing is more instant, thereby releasing the computing performance of the cloud layer for optimal distribution of the edge calculation; and the electric vehicle charging efficiency and the user charging experience quality are improved.

Description

technical field [0001] The invention belongs to the technical field of power system communication, and in particular relates to an electric vehicle charging navigation system based on edge computing. The invention also relates to an electric vehicle charging navigation method based on edge computing. Background technique [0002] The rapid development and promotion of electric vehicles is inseparable from a convenient charging infrastructure system. The continuous driving of electric vehicles depends on the charging capacity of the charging facilities. There is a strong coupling between EV charging efficiency and charging facility selection. The charging behavior of users is highly uncertain. Centralized and disorderly charging will lead to long queuing time, which not only affects the revenue of the power station, but also reduces the quality of user experience, and even affects the stable operation of the power grid. [0003] At present, there are many studies on the c...
