生ずるという大きな問題点があった。Problems to be Solved by the Invention In the above charging method, when a lead storage battery that has been overcharged and then left (hereinafter referred to as "overdischarge left battery") is charged, the internal resistance of the overdischarge left battery is Since it is high, the charging current is small and it is difficult to charge. This tendency is remarkable in the cathode absorption type sealed lead-acid battery with a small amount of electrolyte, and in particular, in the sealed lead-acid battery, a method of charging with a minute current (hereinafter referred to as “trickle charge”) was used after detecting the end-of-charge voltage. Since many chargers are used, when an over-discharged battery is charged by this type of charger, the charging voltage reaches the end-of-charge voltage immediately after the start of charging due to the high internal resistance of the over-discharged battery, that is, There was a big problem that the torque charge was started, resulting in almost no charge.
問題点を解決するための手段 本発明は上記の問題点を解決するもので、充電開始後、
通常の充電とは逆方向の電流を電池電圧が負の状態まで
所定時間流した後に通常の充電に入ることを特徴とする
ものである。Means for Solving Problems The present invention is to solve the above problems, and after charging is started,
It is characterized in that a current in the opposite direction to the normal charging is applied for a predetermined time until the battery voltage becomes negative, and then the normal charging is started.

リクル充電に入る形の従来の充電器で過放電放置電池を
充電した場合には、前述した様に充電直後にトリクル充
電に入ってしまうが、過放電放置電池の内部抵抗が高い
ためトリクル充電時の充電電圧は通常のトリクル充電電
圧より高くなる。従って、この電圧を検出して通常の充
電とは逆方向に電池電圧が負の状態まで所定時間電流を
流した後に通常の充電に入る様にすると、過放電放置電
池及び通常の放置電池両方の充電が可能である。Action The present invention, which has the above-mentioned features, can charge an over-discharged battery. It is considered that this is because the internal resistance is decreased by passing a current in the reverse direction to the normal state in the over-discharged battery. Also, if a conventional charger that starts trickle charging after detecting the end-of-charge voltage is used to charge an over-discharged battery, it will start trickle charging immediately after charging as described above. The charging voltage during trickle charging is higher than the normal trickle charging voltage due to the high internal resistance of the. Therefore, if this voltage is detected and normal charging is started after flowing a current for a predetermined time in a direction opposite to that of normal charging until the battery voltage becomes negative, both of the over-discharged and uncharged batteries are left. Can be charged.

Normally, charging is performed with a quasi-constant current, and trickle charging is performed after detecting the end-of-charge voltage. It is a charger that enters normal charging after passing a current in the opposite direction for a time. That is, the output of the transformer rectification unit 2 that receives the AC power supply 1 as an input is connected to the lead storage battery 11 through the current control unit 3, the backflow prevention diode 9, and the relay contact 10. The control unit 6 receives the first voltage detection unit 7 and the second voltage detection unit 8 as inputs, is connected to the timer 5, and outputs the current control unit 3 into which the resistor 4 enters in parallel. During normal charging, control unit 6 detects the end-of-charge voltage from the output of first voltage detection unit 7 and controls current control unit 3 to perform trickle charging. The second voltage having a higher detection voltage than the first voltage detection unit 7
The voltage detection unit 8 operates when an over-discharged battery is connected, and the control unit 6 operates the timer 5 and switches the relay and the contact 10 to flow a reverse current for a predetermined time.
