Payment method of offline charging equipment based on mobile terminal

Abstract

The invention discloses a payment method of offline charging equipment based on a mobile terminal. The payment method comprises the following steps: inputting a charging starting command on a charging pile, generating a unique starting request two-dimensional code by a control unit encryption algorithm of the charging pile and displaying the unique starting request two-dimensional code on a screen, scanning the unique starting request two-dimensional code by the mobile terminal, and sending the unique starting request two-dimensional code to a service center; receiving a starting request by the service center, performing decryption, generating a transaction response identifying code, scanning the transaction response identifying code by the charging pile, decrypting and verifying the legality of the transaction response identifying code, unlocking a charging gun after the verification is passed, starting charging, and transmitting the cost to the service center; and generating a payment two-dimensional code from the payment information by means of the encryption algorithm by using the charging pile and displaying the payment two-dimensional code in the screen, scanning the payment two-dimensional code on the screen, communicating with a transaction center and performing payment, sending payment information to the service center after the payment is completed, and connecting the service center with the transaction center for verifying the authenticity of the payment information. The payment method is high in safety, flexible to use, and high in popularization value.

Description

technical field [0001] The invention relates to a payment method for offline charging equipment based on a mobile terminal. Background technique [0002] With the advancement of national policies, the National Development and Reform Commission issued the "Notice on Issues Concerning the Electricity Price Policy for Electric Vehicles", which clearly implements price concessions for electric vehicle charging and swapping facilities, and encourages social capital to enter the charging and swapping market, thereby greatly Added charging pile operating companies and manufacturers. However, the payment operation of charging transactions has always been a major problem that has plagued unified operations. At present, cash or prepaid stored value cards are mostly used, and each company issues independent stored value cards and recharge and payment systems. There is a big gap and they cannot communicate with each other, which hinders the popularization and application of charging pi...

Problems solved by technology

[0003] In order to solve the above problems, the present invention proposes a mobile terminal-based payment method for offline charging equipment. This method solves the problem that the equipment must be online in the traditional mobile payment method. Both the charging pile and the service center use asymmetric double-key encryption method for communication, adding a mobile online payment method for discrete charging and swapping equipment
