Zusammenfassung:	PURPOSE:To easily measure the charging degree without troublesome operations by making pipes for an electrolytic liquid supply and discharge transparent ones and measuring the light refractive index of the electrolytic liquid by a light receiving unit whose installation angle and installation position can be finely controlled. CONSTITUTION:An electrolytic liquid 5 is circulated from a positive electrode side tank and a negative electrode side tank through a pipeline 12 by an electrolytic liquid pump. The pipeline is composed of a transparent pipe and the alteration of the refractive index of the electrolytic liquid, which corresponds to the charging degree, is measured by refracting laser beam radiated by a laser oscillator 21 of a light emitting unit near the pipeline 12 and receiving the laser beam by laser light receiver 22 of a light receiving unit. For that, the light receiver 22 is supported by a movable body and its installation position and installation angle are finely controlled, so that the charging degree of zinc- bromine batteries is easily measured without toublesome operations, such as temperature correction of the electrolytic liquid.
