充電する方法も提案されている。2. Description of the Related Art In a conventional charger, when charging a plurality of storage batteries, it is usual to charge one storage battery with one charger. However, recently, in order to reduce the installation area of the charger, a method of charging a plurality of storage batteries by providing an output switching circuit in one charger has been proposed, as in JP-A-61-273134. .

電時間の充電する複数倍の充電時間となる。As described above, by charging a plurality of storage batteries with one charger, there is an advantage that the installation area of the charger can be reduced and the usage rate of the charger can be increased. However, if the charging of one storage battery is completed and then the charging of the next storage battery is started, the charging time is a multiple of the charging time of one storage battery.

必要になるなどの欠点があった。また、放電後充電する
まで長時間放置することは、特に鉛電池の場合には寿命
に悪い影響を及ぼす欠点もあった。For example, assuming that one storage battery is charged for 8 hours, it takes 16 hours to complete two storage batteries, and it may not be in time when the battery is used at night for the next morning. Further, in the case of charging one storage battery with one charger, there is a defect that a large power supply capacity is required if a plurality of storage batteries are charged at the same time. Further, leaving the battery for a long time after charging after discharging has a drawback that it has a bad influence on the life, especially in the case of a lead battery.

【課題を解決するための手段】本発明は、これらの欠点
をなくすため通常の蓄電池の充電に採用している二段階
充電電流方式を採用し、大電流の整流器と小電流の整流
器とに分けて一つに組み込んだ充電器で複数の蓄電池を
充電することにしたものである。The present invention adopts a two-step charging current system which is used for charging an ordinary storage battery in order to eliminate these drawbacks, and is divided into a large current rectifier and a small current rectifier. It was decided to charge multiple storage batteries with a charger built into one.

流器は次の蓄電池の充電を行うことで充電時間の短縮を
図ったものである。The set value of the current varies depending on the type of the storage battery, the ambient temperature, and the like. As an example, first, a current with a 1-hour discharge rate of the nominal capacity is charged by a large-current rectifier to obtain the temperature and gas. When a specified value is reached by detection of occurrence, voltage rise, etc., the 20-hour discharge rate current is switched to be charged by a small-current rectifier for 8 hours, during which the large-current rectifier charges the next storage battery. By doing so, the charging time is shortened.
【０００７】例えば、１００Ａｈの蓄電池２個の充電時
間を概算して見る。For example, the charging time of two 100 Ah storage batteries will be roughly estimated.
【０００８】従来の方法では、１時間率１００Ａで規定

２０％充電とする）するのに８時間を要するので、１台
の蓄電池を完全充電するのに８.８ 時間必要になる。２
台目を続いて充電するとこの２倍の１７.６ 時間の充電
時間が必要になる。In the conventional method, if the battery is charged at a rate of 100 A per hour until the specified voltage is reached and the charged amount is about 80% of the capacity, it means that 80 Ah is charged for 0.8 hours. Next, at a discharge rate of 20 hours and a current of 5 A, the capacity of 12
Charged with a small current rectifier up to 0% (normal efficiency to 1% capacity)
It takes 8 hours to charge to 20%), so it takes 8.8 hours to fully charge one storage battery. 2
If you continue to charge the second unit, you will need double the charging time of 17.6 hours.

Charge the first battery with a high-current rectifier for 0.8 hours, then charge it with a small-current rectifier for 8 hours, and after the first battery's high-current charging is complete, charge the second battery's high-current with That is, the time for the first storage battery to be fully charged is 8.8 hours, and the time for the second storage battery to be fully charged is only 0.8 hours delayed from the first storage battery. Can be completed.

In a charger that receives electric power from a three-phase or single-phase AC power source 1 to charge a plurality of storage batteries in a two-stage current charging system, Alternatively, the charger 2 supplied with electric power from the single-phase AC power source 1 passes through the circuit breaker 3 and the transformer 4, and then the high-current rectifier 5
To the charging terminals through switching circuits 6, 7 and 8, and the transformer 4 to the small current rectifiers 9, 10 and.
11 is a switching circuit 6, in parallel with the rectifier 5.
It is connected to the charging terminal through 7 and 8. The switching circuits 6, 7, and 8 receive information on the storage battery, for example, charging voltage, storage battery temperature, presence or absence of gassing, and when the preset value is reached, the rectifier 5 causes the rectifiers 9, 10 and 11 to operate. It is characterized in that it is configured to connect a charge detector 12 which gives a switching signal to each and charge the storage batteries 13, 14, 15 connected to the charging terminals.

ような機能を充電検知器１２にもたせておく。Charging is started by turning on the circuit breaker 3 in the charger 2 connected to the three-phase or single-phase AC power source 1, and the voltage is reduced to a required voltage by the transformer 4 and rectified into a direct current by the rectifier 5. Then, the storage battery 13 is charged through the switching circuit 6. The other storage batteries are not charged at this point. Since the rectifier 5 is charged with a large current, the voltage, temperature rise, or gassing preset by the charge detector 12 is reached in a short time, and when any of these or a combined setting is reached, A circuit is configured so that a signal is supplied to the switching circuit 6 and switching is performed so that the rectifier 9 charges the storage battery, and at the same time, a signal is also supplied to the switching circuit 7 so that the storage battery 14 can be charged from the rectifier 5 through the switching circuit 7. Next, as with the storage battery 13, the storage battery 14 is also switched by the charge detector 12 at the time when it detects that the preset value has been reached, and the switching circuit 7 is switched to charge from the rectifier 10.
At the same time, the charge detector 12 also provides a signal to the switching circuit 8 so that the storage battery 15 can be charged from the rectifier 5 through the switching circuit 8. This is repeated for the charger terminals. If the storage battery is not connected to the charging terminal, the charging detector 12 can detect it, for example, by detecting that nothing is connected to the charging terminal or no current flows, and the charging terminal 12 is detected. The charge detector 12 is provided with a function of charging the battery by skipping it to the next storage battery without being connected to the rectifier.

短いほど各蓄電池の充電完了時間の差が小さくなる。This is a method of charging each storage battery in a pulsed manner by time division, instead of continuously supplying a large current to one storage battery. The time for one pulse to flow a large current is
It can be freely selected within the range of several milliseconds to several tens of minutes, and the pulse width can be changed at the beginning and the end so that efficient charging can be performed. However, in the case of pulse charging, the time of continuous flow to one storage battery is changed depending on the number of pulses. That is, the charge detector 12 outputs a signal so that a pulsed current (in the case of pulse charging, a pulse group) from the large-current rectifier 5 is sequentially supplied to each storage battery. Between the current of the pulse, if the current is made to flow with the small current rectifier,
Further, the charging time is shortened, and the shorter the pulse width of the plurality of storage batteries, the smaller the difference between the charging completion times of the storage batteries.
【００１９】大電流での充電時間は、前の実施例と同じ

The installation area of the battery can be reduced, and the capacity of the power supply can be significantly reduced as compared with charging a plurality of storage batteries with a plurality of chargers.
