Description of the Related Art In a conventional charger, the type of battery that can be charged (rated voltage, current capacity, etc.) is fixed, and it is not possible to charge a plurality of types of batteries with one charger. The reason for this is as described below. That is, since the charging characteristics are determined by the type of battery, normal charging cannot be performed unless the charging voltage or current is appropriate for charging the battery in order to charge the battery. It was However, in the conventional charger, the voltage and current characteristics at the time of charging are fixed so as to be compatible with one type of battery, so that one charger can charge only one type of battery.

数種類のバッテリに充電を行うことはできなかった。Therefore, in order to charge a plurality of types of batteries having different rated voltages and current capacities, it is necessary to prepare chargers corresponding to the number of types of batteries. However, in recent years, when there are many battery-driven electric products and the types of batteries are abundant as shown in FIG. 5, it is too costly to prepare a charger for each type of battery to be charged. In addition, there is a drawback that it is complicated and that an error such as charging with a charger that is not compatible with the battery may occur. Therefore, if multiple types of batteries are charged with one charger, the batteries that do not match the charging characteristics will not be charged properly, but the battery and the charger will be burdened, and the performance of the charger will deteriorate and the battery will be destroyed. However, it has been impossible to charge a plurality of types of batteries by using one charger.

Side power connector section 16 and the battery 2 side power connector section 21 are coupled. At the same time, the reading unit 12 of the charger 1
Reads the battery individual information providing unit 22 of the battery 2 and passes the read battery individual information (type of battery, rated voltage, current capacity, etc.) to the control unit 11. Here, the battery individual information providing unit 22 is, for example, a barcode, and the reading unit 12 is a barcode reader. The control unit 11 determines the type and charging characteristic of the battery from the battery individual information input from the reading unit 12, and controls the power supply unit 14 to supply a voltage or current that matches the charging characteristic of the battery 2 to the power supply connector unit. The battery 2 is supplied from 16 to start charging.

The control unit 11 controls the output voltage or current of the power supply unit 14 based on the feedback information from the detection unit 15 so as to follow the charging characteristics, and continues charging the battery 2. Further, the control unit 11 monitors the charging time for the battery 2 based on the time information supplied from the timer unit 13, and when the charging time determined by the type of the battery comes, stops the power supply output from the power supply unit 14. To end charging.

The switch circuit 146 in FIG. 2 is switched to the terminal c side, and the power supply output to the battery 2 is off.
When the charging is started, the switch circuit 146 is switched to the terminal a side or the terminal b side under the control of the control unit 11. That is, depending on the type of battery 2 to be charged as shown in FIG. 5, when the control unit 11 wants to charge by constant voltage control, the control unit 11 sets the switch circuit 146 to the terminal a side and when it wants to charge by constant current control, Switch to side b. Therefore, when it is desired to perform constant voltage control, the control unit 11 switches the switch circuit 146 to the terminal a side and changes the resistance value of the attenuator 143 to generate a constant voltage corresponding to the type of the battery 2 in the switch circuit 146. The voltage is controlled to be applied to the terminal a. If you want to perform constant current pressure control,
The control unit 11 switches the switch circuit 146 to the terminal b side and controls the resistance value of the attenuator 144 so that the switch circuit 146 is connected from the collector of the transistor 145.
The current supplied to the terminal b is controlled so as to be a constant current corresponding to the type of the battery 2. After that, when the control unit 11 determines from the charging characteristics of the battery 2 that charging is completed, it switches the switch circuit 146 to the terminal c,
The supply of voltage / current to the battery 2 side is stopped.
