| 摘要 |
The invention discloses a method for detecting a charging state of a vanadium cell, which comprises the following steps of: (1) using an angular spectrum type surface plasma resonance sensor to detect electrolyte of the vanadium cell, obtaining surface plasma resonance angular spectrum information of the electrolyte, and calculating to obtain a surface plasma resonance angle and/or refractive index of the electrolyte; and (2) inquiring or calculating to obtain the charging state of the vanadium cell according to the preset surface plasma resonance angle and/or the refractive index of the electrolyte under various parameters and a data bank related to the charging state. According to the method, the charging state of the vanadium cell can be detected on line, the imbalance can be known in real time, and thus a system can be adjusted when the vanadium cell is in an unideal state. |
