AI Technical Summary
Existing methods for detecting electrolyte concentration in vanadium redox flow batteries suffer from low accuracy, low efficiency, and high cost, making it difficult to meet the needs of large-scale, batch testing, and the results are not timely.
A multi-channel electrolyte ion concentration detection device is adopted, including a DC power supply, a host computer, and at least two detection units. Each detection unit includes a circulation loop for the solution to be tested and an electrolytic cell. The ion concentration is measured by coulometric analysis. The host computer automatically identifies the moment of voltage signal change using a reference cell and combines Faraday's law to calculate the ion concentration.
It enables high-precision and high-efficiency large-scale batch detection of electrolyte ion concentration, reduces hardware costs, reduces reliance on operators' professional skills, and ensures the accuracy and reliability of detection results.
