PURPOSE:To disperse the effect of solution leakage and breakdown and extract battery active material with even concentration by dividing at least one side of a solution storage bath in a plural number and connecting each of them to the battery active material supply piping system of a battery main body through each on/off valve. CONSTITUTION:Two or more solution storage baths 3 are provided in a battery active material supply pipe 1 connected in parallel to the main body of a solution storage type battery through each connecting pipe 4 and on/off valve 5. First the on/off valve of one tank is opened and the battery active material is supplied to the battery main body through the connecting pipe 4 and piping 1 using a pump 2. The on/off valve 5 is closed after a preset time and the subsequent on/off valve 5 is opened, then the battery active material is supplied to the battery main body through the connecting pipe 4 and the piping 1 using the pump 2. The same operation is repeated subsequently. As a result, the concentration of the battery active material is averaged and a stable output can be maintained. In addition, even when a leakage accident occurs in any solution storage bath, fault processing can easily be performed within a small scale range without greatly affecting the entire operation. |
