Communication method between the electric vehicle charging and discharging monitoring center and the local monitoring of the charging station

Abstract

The invention provides a method for communicating a charge-discharge monitoring center of an electric automobile with local monitoring modules of a charging station. The method is characterized by comprising the following steps: 1, the charge-discharge monitoring center and a plurality of local monitoring modules are connected through Ethernet; 2, the local monitoring modules acquire information of each charge-discharge station; 3, the charge-discharge monitoring center provides a part of control instructions according to the received information; and 4, the local monitoring modules directly control charge-discharge motors according to the part of control instructions, and the operation jumps to the step 2. According to the method disclosed by the invention, the charge-discharge monitoring center and the plurality of local monitoring modules are connected through Ethernet to carry out communication and information interaction and uniformly control policies, device start or stop of the charge-discharge motors, power size and charge-discharge state switching, thus a system is managed in a unified way and optimally runs, and centralized storage of real-time monitoring and historical data is realized.

Description

technical field [0001] The invention relates to a communication technology in the field of electric vehicles, in particular to a communication method between an electric vehicle charging and discharging monitoring center and a local monitoring station of a charging station. Background technique [0002] 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 in terms of charging and discharging station monit...

Problems solved by technology

However, its disadvantage is that in terms of charging and discharging station monitoring, the existing technology does not have a mature design solution, and there are few charging and discharging stations that have been put into operation. Most of the completed charging and discharging stations are in charging stations. The local monitoring is designed to monitor the equipment in the station, and it does not have the ability to communicate with the upper monitoring system (center). The assets of each charging and discharging station are different, and the application positioning, hardware structure and communication protocol are different. Unified management of the system, optimized operation, real-time monitoring and centralized storage of historical data cause difficulties
