Charging metering method for charging station

Abstract

The invention discloses a charging metering method for a charging station. A charging metering system of the charging station comprises a main processor, a power supply module, a display module, a communication module, an electric energy metering module, a data read-write module, a data storage module, an output module, an output port, a door lock and charging control module and a charging door, wherein the power supply module, the display module, the communication module, the electric energy metering module, the data read-write module, the data storage module, the output module, the output port and the door lock and charging control module are electrically connected with the main processor, and the charging door is controlled to be opened or closed by the door lock and charging control module. The charging metering method has the advantages that the modular design is adopted, and the coupling degree among all functions is reduced; the man-machine interaction practicability and the humanized use experience of the charging metering system are enhanced through the output port, and the reserved expansion space is provided for the system, and the function expansion of the hardwire can be carried out; the high-integration degree and the intelligentization of the system are realized through the automatic updating and the maintenance function of the system; and each function is realized in different stages, the stages are divided according to the function requirement, the phased implementation is carried out according to the importance program, and the function repetition or the function turbulence caused by the mutual influence because of the simultaneous communication among the modules is avoided.

Description

[0001] This application is a divisional application, the application number of the original application is 2011104203302, the application date is 2011-12-15, and the title of the invention is a charging metering system and metering method for a charging station. technical field [0002] The invention relates to a charging station providing charging service for electric vehicles, in particular to a charging metering system and metering method of the charging station. Background technique [0003] With the worsening of the global energy crisis, countries all over the world are trying to find ways to save energy, reduce consumption, recycle energy, and clean and non-polluting energy. As a necessary means of transportation for people's daily life, automobiles consume a lot of energy and cause pollution. A kind of clean energy has become more and more popular, and the world's major automobile manufacturers are also working hard to develop electric vehicles to gradually replace fue...

Problems solved by technology

The current common technology is to realize carrier communication through power line communication technology. For high-speed transmission of large amounts of data, the limitation of this technology is the disadvantage of transmission distance.

In addition, a wired LAN can be used to connect to the terminal server. The difference between a wired LAN and a PLC network is that a dedicated line is used to carry communication signals. Ethernet is the most common technology, but this technology requires dedicated line laying, and the cost is high.

The wide-area network is the computer network with the widest coverage. At present, WAN, such as the Internet network, has been used to realize data communication. However, the problem in this technical village is relatively common: the data is transmitted to the main station computer in the form of encrypted data packets. In this way, there are usually problems of network delay, disconnection or data corruption, and these problems usually occur in the user terminal-the integrated system of the charging facility. As mentioned above, the system integration of the charging system is not perfect and the design is not enough Only humanization can lead to such problems
