摘要

The present invention relates to a method and a system for monitoring and measuring a charge state of a flow battery system, a flow battery based on a redundant design of an SOC detection device, a method and apparatus for determining the actual capacity of a flow battery, and an input on the AC side of the flow battery. An output characteristic estimation method and system are provided. The present invention guarantees accurate charge state monitoring measurement results in real time, which is advantageous for improving the efficiency of use of the flow battery, extending the service life of the battery, and accurately managing the flow battery system. . In the monitoring and measuring method, the SOCs of at least two pairs of different monitoring locations are determined, and any one of the monitoring locations is in a positive electrode electrolyte storage tank, a negative electrode electrolyte storage tank, Each of the pairs of monitoring points corresponds to the positive electrolyte outlet pipe and the negative electrolyte outlet pipe of the pile, or the positive electrolyte inlet pipe of the pile and the negative electrolyte inlet pipe of the pile. Thus, a procedure for obtaining the total charge state SOC of the flow battery system is provided. [Selection] Figure 1
