。Structure of the Invention In the present invention, the voltage of the battery rises during charging, and the base of a transistor is connected via a resistor to the anode of a thyristor that detects and maintains the charging completion voltage. It is connected to a power source through a light emitting diode in series. When the power source is connected, the light emitting element lights up, and when the thyristor is turned on, which detects that the voltage of the storage battery has reached the charging completion voltage, the transistor is turned off.
NL, the light emitting element turns off, thereby making it possible to reliably know that charging has been completed.

In FIG. 16 and a capacitor 17 are connected to form a DC power source. 019 is a constant voltage diode that determines the voltage of the storage battery 15 during stage separation, and 18 is a first thyristor that controls charging and supplies power. Then diode 16.
When a signal enters its gate through the resistor 21, the ON-element storage battery 15 is charged. When the voltage of the storage battery 15 exceeds the voltage regulator diode 19, it passes through the voltage regulator diode 19 and is connected to the second thyristor 2.
A signal enters the gate of 0, so the same thyristor 20 becomes 0.
The current flowing into the gate of the first thyristor 18 flows in the direction of the second thyristor 2o. Therefore, the first thyristor 18 is turned off and no current flows through the storage battery, and charging ends here. When the second thyristor 20 is off, current flows into the gate of the first thyristor 18 and passes through the resistor 22 to the transistor 26.
The transistor 26 is turned on from this point.
,, current from the power supply flows through the resistor 23 and the light emitting diode 24 connected in series with the collector. Therefore, the light emitting diode 24 lights up. When the voltage of the storage battery 15 reaches the completion voltage and the second thyristor 2o is turned on, the current flowing into the base of the transistor 25 stops flowing to 0FFL, and the light emitting diode 24 also stops having current flowing therein and turns off.

用時間を一定にし、同電池を最大限に使用できる。Effects of the Invention As is clear from the above embodiments, the present invention has a simple configuration in which the base of a transistor is connected to the anode of the second thyristor via a light emitting diode, and the light emitting diode is turned on while the storage battery is being charged. When the charging is completed, the light emitting diode turns off, so that it is possible to reliably display that charging is in progress and that charging has been completed. In addition, by fully charging the battery until it is fully charged, the usage time of the storage battery can be kept constant and the battery can be used to its maximum potential.

い。Furthermore, since it is possible to tell when charging is complete, there is no shortage of charge in the storage battery, and it has the effect of extending its lifespan.Although a light emitting diode was used as the display element in this example, the same effect can be achieved with a light emitting element such as a lamp. It goes without saying that there is.
