Abstract

PURPOSE:To easily detect the charge-discharge state of a cell by immersing a measuring part comprising a refractometer and a thermometer in an electrolyte to measure a refractive index and temperature, and by measuring the charging state of the electrolyte based on the refractive index and the temperature. CONSTITUTION:A measuring part 10 comprising a refractometer for measuring the refractive index of an electrolyte 9a and a thermometer for measuring its temperature and a charging state measuring means for detecting the charging state of the electrolyte 9a based on the refractive index and the temperature obtained with the measuring part 10 are installed. The measuring part 10 is immersed in the electrolyte 9a to measure the refractive index and the temperature, and the charging state of the electrolyte 9a is measured based on these data. The charging state information which is important for cell operation is easily obtained, and flow rate control and malfunction detection are easily performed to ensure the maintenance and safety operation of the cell.
