System and method for charging billing of electric vehicle during network anomalies

Abstract

The invention relates to a system and a method for charging billing of an electric vehicle during network anomalies. During the network anomalies, a user holds a terminal by hand to connect a centralized control through a WiFi network and submits a charging request of the user to the centralized control, after the centralized control compares a VIN (vehicle identification code) with a post blacklist stored in the centralized control after acquiring the VIN, and if the VIN is not in the blacklist, the centralized control starts a charger to perform charging billing on the electric vehicle through a charging module, stores charging information and arrearage data, then uploads the charging information and the arrearage data to a cloud server when the network is normal, and requests a newest post blacklist from the cloud server; the cloud server sends arrearage information to the user after receiving the charging information and the arrearage data which are uploaded by the centralized control; the cloud server sorts a new post blacklist and sends the new post blacklist to centralized controls of various charging stations; the cloud server receives payment information of the user and updates the blacklist. According to the method, the charging request is finished through access of a local area network; the vehicle is positioned uniquely by acquiring the VIN of the vehicle, the identification rate is high, and the feasibility is good.

Description

【Technical field】 [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to a charging charging system and method for electric vehicles when the network is abnormal. 【Background technique】 [0002] With the progress of society and the enhancement of environmental protection awareness, electric vehicles are gradually favored because they are powered by vehicle-mounted power supplies and can solve the problems of exhaust emissions from fuel vehicles, pollution of the environment, and high energy consumption. [0003] At present, most of the existing electric vehicle charging systems are based on charging piles, and the billing and control systems are synchronized to the cloud server through the network, including user management and billing. In this case, when the network is interrupted or abnormal, the communication between the cloud server and the charging device is disconnected, and the user who needs to charge the vehicl...

AI Technical Summary

Problems solved by technology

In this case, when the network is interrupted or abnormal, the communication between the cloud server and the charging device is disconnected, and the user who needs to charge the vehicle cannot initiate a charging request through the existing mobile APP

The current charging system cannot meet the user's requirements for charging the vehicle through the mobile phone APP when the network is abnormal. Generally, card issuance is used, but it is easy to be terminated in advance by others.
