算誤差を補正していた。However, in reality, even a slight calculation error becomes large as a product W error over a long period of time, and the value of charging efficiency 77 changes depending on the charging/discharging current value and the amount of electricity held, especially at the end of charging. Due to the extreme decrease in efficiency, etc., a large error will not occur between the actual amount of electricity ^H held in the storage battery (4) and the calculation result over a long period of time. In order to prevent this, the conventional storage battery monitoring device (9) periodically turns on the switching Yonago (8b) of the auxiliary power supply (8), for example once a week, to monitor the amount of electricity ^H
The storage battery (4) was overcharged until it reached about 120%, and then the stored electricity Jt8H was reset to 100% to correct the integration error.

。(11) is, for example, a float-type specific gravity sensor that is installed in the battery case (4a) of the storage battery (4) and serves as a lower limit detection means for detecting the specific gravity of the electrolyte in the storage battery (4). It has a contact (lla) that closes (makes) when the value falls below a specified value. A detection signal from the contact (lla) is input to the storage battery monitoring device (9^).

The storage battery monitoring device (9^) monitors the charging and discharging current of the storage battery (4). Using , measure the electricity 1811 held by the storage battery (4) by calculating the equation (2) in the same manner as above, and control each switch (3), (6) and switching element (8b) based on the result. are doing.
ここで、前述の理由によ、り蓄電池監視装置（９＾）に
おける演算計測値に積算誤差を生じた渇きについて述べ

補正することができる。First, when the integration error is negative, the actual amount of electricity ^H stored in the storage battery (4) gradually approaches the upper limit (charging) compared to the calculated value calculated by formula (■), but the terminal of the storage battery (4) As shown in FIG. 2, the voltage vB tends to rise sharply near the upper limit of the amount of electricity ^H held (at the end of charging). Therefore, the storage battery monitoring device (9^) detects the terminal voltage Ve.
is constantly detected, and when the prescribed upper limit voltage value VBM is reached, the held electricity 1811 calculated by calculation is corrected to HN' to the upper limit value of the held electricity E corresponding to the upper limit voltage value VBM of the terminal voltage. I can do it.
尚、充電特性は充電電流値ＩＢ及び環境温度によって変

うことができる。Incidentally, since the charging characteristics change depending on the charging current value IB and the environmental temperature, if the upper limit voltage value VBN is made variable depending on the charging current value 8 and the environmental temperature, even more accurate correction can be made.

限値に補正することができる。Next, when the integration error is positive, the actual amount of electricity ^H held by the storage battery (4) gradually discharges toward the lower limit than the calculated measured value. Since the specific gravity of the electrolytic solution in the battery container (4a) decreases approximately in proportion to the amount of discharge, the actual amount of electricity ^H held in the storage battery (4) can be determined from the specific gravity value of the electrolytic solution. Further, the specific gravity sensor (11) is set so that the contact point (lla) is closed when the specific gravity of the electrolytic solution of the storage battery (4) reaches a prescribed lower limit specific gravity value. Therefore, the storage battery monitoring device (9^) is activated by the contact (lla) closing signal from the specific gravity sensor (11).
can be corrected to the lower limit value of the retained electricity 1^H corresponding to the lower limit specific gravity value of the electrolytic solution.

を実現することができる。Note that the specific gravity value of the electrolyte varies somewhat depending on the electrolyte temperature, that is, the environmental temperature, but in the case of a float-type specific gravity sensor 11), if a material with appropriate thermal expansion is selected as the float material, it will not change due to changes in the environmental temperature. A specific gravity sensor (11) that can compensate for fluctuations in the operating point of the contact (lla) and has relatively good reproducibility.
can be realized.
こうして、演算計測結果に積算誤差が生じても、蓄電池
（４）の保有電気量＾■を、規定の上限値と下限値との

Since the correction is made, the storage battery can always be operated between the upper and lower limit values without periodic overcharging, suppressing the power loss and shortening of the battery life, and preventing the electrolyte from decreasing. This has the effect of providing a storage battery monitoring device that is possible.
