本発明はニッケルカドミウム蓄電池ある(・はこれと同
様の特性を有する蓄電池(以下電池という)を充電する
充電方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for charging a nickel-cadmium storage battery (hereinafter referred to as a battery) having similar characteristics.
従来、電池を短時間で充電する場合、電池を充電しつつ
、電池の温度、端子電圧などの各種物理的変化を検出す
ることにより充電の完了を知り、その後充電電流の減少
あるいは充電の停止をすることにより、いわゆる電池の
過充電を防止していた。Conventionally, when charging a battery in a short period of time, it is necessary to know when charging is complete by detecting various physical changes such as battery temperature and terminal voltage while charging the battery, and then reduce the charging current or stop charging. This prevents so-called overcharging of the battery.
しかしながら、このような方法では電池の物理的変化を
検出するためのセンサーが必用となり、それ故に、充電

知ることが困難で、それ故に電池の充電が不完全になっ
たり、また過充電により電池を劣化させたりすることが
多かった。However, such a method requires a sensor to detect physical changes in the battery, and therefore has the disadvantage that the charging circuit becomes complicated. Furthermore, depending on the method, detection of the above-mentioned physical changes under a wide range of environmental conditions is technically expensive, and therefore the manufacturing cost is high. On the other hand, when charging is controlled using a relatively simple method, it is difficult to accurately know when charging is complete because battery characteristics change depending on the battery condition and environment such as temperature. In many cases, charging became incomplete or overcharging caused battery deterioration.
本発明は以上のような従来の充電方法の欠点に鑑み、電
池を充電する前に放電用負荷を用いて一旦電池を所定電

の充電方法を得るにある。In view of the above-mentioned drawbacks of the conventional charging method, the present invention has been developed by first discharging the battery to a predetermined voltage using a discharging load before charging the battery, and then charging the battery to a certain amount. The object of the present invention is to provide a battery charging method that can overcome the drawbacks mentioned above.

When the WIA is switched as shown, the transformer 6A is separated from the internal circuit, resulting in two discharge loads. Then, the battery l is once discharged to a predetermined voltage before being charged. That is, the battery 1 has its direct current converted to a transformed current by the DC/AC converter, and is discharged using the transformer 6A as the discharge load 2A. Due to the discharge, the voltage of the battery (point A) decreases, and when it drops to a certain predetermined voltage as described above, the battery voltage detection circuit 4 is activated, switches the switch 5WIA to the side opposite to that shown in the figure, and starts the charging timer 5. Start. The charging operation after the charging timer 5 starts is the same as that of the embodiment shown in FIG. 1 above. In the case of this embodiment, it is also conceivable to provide the transformer with a winding dedicated to discharge, as shown in FIG. 3 or FIG. 4. That is, in the case of a transformer having an outer iron core 13 as shown in FIG.
A copper plate 15 dedicated to discharge may be wound around the central outer circumferential portion around which the No. 3 coil 14 is wound. In addition, in the case of a transformer having an inner iron core 13A as shown in FIG.
A copper plate 15A dedicated for discharge may be wound around the outside of the secondary winding 14A of A. Furthermore, although not particularly shown in the drawings, in the case of FIG. 283, a copper plate exclusively used for discharge may be interposed between the chemical primary winding and the secondary winding.
