Vanadium battery management system and achieving method thereof

Abstract

The invention relates to a vanadium battery management system and an achieving method thereof. The system comprises an upper computer, a main control module, an analog quantity unit and a digital quantity unit. The analog quantity unit and the digital quantity unit are in communication connection with the main control module, and the main control module is in communication connection with the upper computer. The method includes that the upper computer, the main control module, the analog quantity unit and the digital quantity unit are in communication connection, hardware addresses of the modules are manually set, the main control module conducts data transmission with the modules in real time, a set value is set, vanadium battery circuit systems are started, and all feedback values in the vanadium battery circuit systems are transmitted to the main control module to be processed and transmitted to the upper computer. If the system operations abnormally, the vanadium battery circulation system emergency protection program is executed, and the step of digital quantity unit and analog quantity unit inquiry by the main control module is returned. The digital quantity module and the analog quantity module can achieve multiple extension as much as possible, the method is simple and convenient, the development progress is improved, and real-time information interaction between the system and other devices can be achieved.

Description

technical field [0001] The invention relates to a vanadium battery management system, in particular to a vanadium battery management system and its realization method. Background technique [0002] The existing vanadium battery cycle operation system includes a vanadium battery stack, a vanadium battery management system, a charging and discharging device, a positive electrode liquid storage tank and a negative electrode liquid storage tank, a positive electrode circulation pump and a negative electrode circulation pump, such as figure 1 shown. The vanadium battery management system is responsible for the start-stop control of the circulation pump of the positive and negative liquid storage tanks and the monitoring and alarm of the flow, temperature, pressure, liquid level, etc. of the vanadium battery electrolyte. The vanadium battery management system can manage The upper computer software of the control cabinet of the system realizes monitoring and control. The charging...

AI Technical Summary

Problems solved by technology

[0003] In the current state, for vanadium battery systems of a single vanadium battery stack or multiple vanadium battery stacks, due to the limitation of the number of digital and analog quantities carried by each main control unit, when the vanadium battery contained in the vanadium battery system When the number of stacks increases, the vanadium battery management system needs to carry out completely different electrical selection and software programming for the main control unit, which brings a lot of inconvenience to subsequent debugging, so look for a vanadium battery management system that can achieve sufficient expansion system problems arise
