Communication method between electric automobile monitoring system and charge and discharge machine

Abstract

The invention provides a communication method between an electric automobile monitoring system and a charge and discharge machine, which is characterized in that the method comprises the following steps that: 1) communication connection is established between the monitoring system and a plurality of charge and discharge modules; 2) the charge and discharge modules transmit the working conditions of the charge and discharge modules and the battery information of an electric automobile to the monitoring system; 3) the monitoring system analyzes and stores the information data transmitted by the charge and discharge modules; 4) the monitoring system sends control commands to the charge and discharge modules; and 5) the charge and discharge modules charge and discharge the electric automobile and jump to the step 2. A general packet radio service (GPRS) method can be adopted for communication, the communication method is suitable for scattered charge and discharge machines, the hardware cost of the monitoring system is reduced, the system operability is improved, and the construction and the popularization of the charge and discharge monitoring system are facilitated. Moreover, Ethernet and serial ports can also be adopted for communication. Not only can the monitoring system be conveniently accessed to other systems, but also the network security of a company can be ensured at the same time when the reliable access of the system is ensured.

Description

[0001] technical field [0002] The invention relates to a communication technology in the field of electric vehicles, in particular to a communication method between an electric vehicle monitoring system and a charging and discharging machine. Background technique [0003] According to relevant surveys, by 2020, the electric vehicle market in Shanghai is expected to reach approximately 350,000 vehicles (calculated based on a market penetration rate of 15%). According to the research results of related subjects, when the number of electric vehicles in Shanghai reaches 350,000, the number of fast charging devices will reach thousands, the number of slow charging devices will reach hundreds of thousands, and the scale of charging and discharging facilities will be very large. At present, Shanghai has built 8 electric vehicle charging (discharging) power stations. However, its disadvantage is that there is no mature design solution in the prior art in terms of charging and dis...

But its disadvantage is that, in terms of charging and discharging station monitoring, the existing technology has no mature design scheme

At present, there are few charging and discharging stations that have been put into operation. Most of the charging and discharging stations that have been built are monitored locally at the charging station to monitor the equipment in the station. They do not have the same level as the upper monitoring system (center ) ability to communicate, the ownership of assets of each charging and discharging station is different, and the application positioning, hardware structure and communication protocol are all different, which makes it difficult for the unified management, optimized operation, real-time monitoring and centralized storage of historical data of the system
