摘要

The present invention relates to a method for monitoring electrolyte charging states of a redox flow battery in real time in-operation, and a redox flow battery capable of monitoring electrolyte charging states in real time in-operation, and more specifically, to a method which measures voltages of electrolytes and UV-vis absorbance, respectively, through a voltage measuring cell installed in pipes of a cathode electrolyte circulation unit and an anode electrolyte circulation unit and/or open circuit voltage measuring cells and UV-vis cells, and compares the same to monitor charging and discharging states of electrolytes in real time, and to a redox flow battery capable of monitoring electrolyte charging states in real time in-operation. The present invention measures the absorbance with a measuring solution (electrolyte itself) as a reference and provides convenience in maintenance. In addition, the present invention measures voltages and UV_vis absorbance of the electrolyte in real time without any loss of capacity of a redox flow battery and compares the same with a calibration curve, thereby being able to monitor charging and discharging states of the electrolyte in real time. Moreover, the present invention measures charging and discharging states of the electrolyte by crossing UV-vis cells along with the voltage measuring cells and OCV cells or simultaneously using the same such that the verification is doubly provided compared with existing technologies, thereby improving accuracy and stability.
