Electric vehicle charging navigation method considering power grid information and charging station information

Abstract

The invention relates to an electric vehicle charging navigation method considering power grid information and charging station information. The power grid information and charging station informationare combined to dynamically adjust charging fee and charging station service fee, wherein the charging fee is calculated based on fluctuating electricity price, voltage quality is reflected with fluctuating charging price, the service fee is calculated with charging station occupation, and occupation degree of each charging station is reflected with fluctuating service fee. An electric vehicle ischarged with the charging station having low charging fee and service fee; the electric vehicle is therefore guided to the charging station with good voltage quality and low occupation for charging.In addition, navigation from a current position to the charging station is considered; the condition that the electric vehicle requires multiple charging during traveling is considered in combinationwith destination information, and therefore, a charging navigation strategy can be provided for a user based on overall optimal cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle charging navigation method taking into account grid information and charging station information. Background technique [0002] With climate change, increasing greenhouse gas emissions, fossil energy depletion and other issues are becoming more and more serious, the development of electric vehicles has attracted increasing attention from the society. Due to the advantages of green environmental protection and zero emission, governments and industries of various countries are increasing policy support for electric vehicles. However, with the massive popularization of electric vehicles in the future, the demand for charging load of electric vehicles will also increase greatly. The disorderly and chaotic charging of large-scale electric vehicles will have an impact on urban power grids and power infrastructure, such as excessive loads, electric ...

AI Technical Summary

Problems solved by technology

The current charging navigation system usually uses the shortest path as the judgment standard to guide electric vehicles to the nearest charging station to charge, ignoring some information about the operation of the power grid and charging station information, such as the voltage situation of the area where the charging station is located, the charging of the charging station Price and service fee price, rechargeable free location information, etc.

In addition, the existing charging navigation system usually reminds the user to charge when the remaining power cannot meet the driving needs of the electric vehicle, and does not combine the real-time information of the destination of the vehicle to comprehensively consider the charging strategy
