Electric vehicle charging method and device based on two-dimensional code

Abstract

The invention provides an electric vehicle charging method and device based on a two-dimensional code. The electric vehicle charging method based on the two-dimensional code comprises the following steps of scanning the two-dimensional code on a charging pile and judging whether user authentication is finished or not; if the user authentication is finished, judging whether a charging working task exists for the user or not; if the charging working task exists, further judging whether information of the charging pile in the charging working task is consistent with the scanned information of the charging pile or not; if the information are consistent with each other, displaying a charging page; and if the information are inconsistent with each other, displaying a charging pile information page. The electric vehicle charging device based on the two-dimensional code comprises a two-dimensional code scanning module, a user authentication module and a working task judging module and is used for realizing the charging method. According to the electric vehicle charging method and device based on the two-dimensional code, the user can clearly know the current charging state; for example, the user can know whether the two-dimensional code is rescanned or not and whether the charging is going to be finished or not.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method for charging an electric vehicle based on a two-dimensional code and a device for realizing the method. Background technique [0002] In recent years, with the increase of automobiles, as the pollutants emitted by traditional automobiles have become more and more serious, people have begun to consider using new energy vehicles, among which electric vehicles using electric energy are widely accepted new energy vehicles in the market. Since electric vehicles do not need to burn gasoline or diesel, and will not emit a large amount of polluting gases during driving, countries are vigorously promoting this environmentally friendly vehicle. [0003] Electric vehicles are driven by electric energy, so a battery for providing electric energy needs to be installed on the electric vehicle. Since the electric energy that the battery can store each time is limited, it needs to be ch...

AI Technical Summary

Problems solved by technology

[0006] At present, there are many applications for charging pile management in the application market. Most of the applications can provide the function of scanning QR codes for charging, but the existing applications generally only design the simplest scanning QR codes for charging. The process, when encountering some branch processes, did not deal with it, causing the user to be unable to perform normal charging

[0007] For example, when the user is not logged in, most applications simply disable the start charging button, and do not guide the user to log in to continue the operation

Secondly, when the user's balance is insufficient, most applications will require the user to recharge before continuing to charge, and require the user to manually operate multiple steps until the recharge interface is successfully recharged and then re-scan the QR code for charging, which seriously affects the user experience.

For another example, when the user is not at the charging site and the charging is about to be completed, most applications do not have a notification mechanism for the user to pick up the car, which wastes the user's time on the one hand, and makes the charging pile not fully utilized on the other hand.
