Charging and billing control system for electric car

Abstract

The invention discloses a charging and billing control system for an electric car. The charging and billing control system comprises a card swiping module, a key module, a storage module, a display module, a charging control module and a microcontroller. The card swiping module is used for achieving non-contact reading and writing of an RF card through RF and transmitting charging consumption data to the microcontroller. The display module is used for displaying clock information, charging electric quantity and consumption sum. The key module is used for inputting preset data and sending the preset data to the microcontroller. The microcontroller is used for receiving the consumption data and the preset data input by the key module, and controlling the charging control module to charge an external device. The storage module is used for storing the consumption data and the preset data. According to the charging and billing control system, unattended operation can be achieved, automatic deduction charging can be achieved, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a control system, in particular to an electric vehicle charge charging control system. [0002] Background technique [0003] The increasing demand for energy in the world and the depletion of natural resources have brought new challenges to energy suppliers, industrial enterprises and consumers. It is imperative to use energy in an efficient and sustainable manner as much as possible. Energy efficiency has an impact on all types of energy conversion: from the efficient generation, transmission and distribution of electricity and heat to the efficient use of energy in industry, buildings and transport. Electric vehicles, a green vehicle powered by electricity, are becoming more and more popular in cities. [0004] Due to the increasing number of electric vehicles in the community, electric vehicles have also brought a lot of trouble and inconvenience. There is an urgent need to establish a complete electric vehicle managemen...

AI Technical Summary

Problems solved by technology

At present, the charging standards of many residential properties are not clear, and many residents are dissatisfied with the fees and pull the wires privately, which not only affects the beauty of the residential area, but also brings great safety hazards. With the "electric vehicle charging station", that is, the automatic charging and billing system of the residential area, It can be realized that there is no need for a special person to be on duty, only one card is in hand, and charging is worry-free, which solves the problems of residents’ charging difficulties and random power pulling in the community, and also brings certain benefits to the property.
