停止して急速充電が完了する。 When charging the lead-acid battery 6, when commercial power is applied to the circuit, a charging current flows to the lead-acid battery 6 through the step-down section 1, the rectifier section 2, and the charge control section 3, and the terminal voltage of the lead-acid battery begins to rise. . When the terminal voltage of the lead-acid battery 6 input to the voltage detection section 5 exceeds a certain set value, the switch section 4 becomes conductive due to the signal from the voltage detection section 5, and the charging control section 3 stops the conduction. Quick charging is completed.

た。 However, in the above circuit, when attempting to charge the lead-acid battery 6 whose internal impedance has become high due to over-discharge, the terminals of the lead-acid battery 6 immediately after the commercial power is applied due to the internal impedance of the lead-acid battery 6 and the charging current. The voltage exceeded the set voltage of the voltage detection section 5, which caused the charging control section 3 to stop conducting, resulting in a drawback that rapid charging was not possible.

は抵抗である。 When the lead-acid battery 6 is connected and commercial power is applied, a current I 1 flows through the step-down section 1 and the rectifier section 2 to the charge control section 3 . This current I 1 flows into the gate of the thyristor SCR1 through the diode D 1 , the resistor R 3 , and the diode D 2 and makes the thyristor SCR1 conductive. The charging current I passing through this thyristor SCR1 is connected to a diode to prevent backflow.
It flows into the lead-acid battery 6 through D 3 and starts charging.
At this time, due to the voltage drop due to the internal impedance of the lead-acid battery 6 and the charging current I, the terminal voltage of the lead-acid battery 6 becomes higher than the set voltage of the voltage detection unit 5, and a current I 2 due to the reverse voltage flows through the Zener diode ZD1. This current I 2 flows into the gate of thyristor SCR2 via resistor R5. Therefore, thyristor SCR2 conducts and the current I1 flows through the diode
D 1 flows into the thyristor SCR2 through the resistor R3,
It returns to the negative electrode through the resistor R6. Therefore, during the next half wave, a gate voltage sufficient to turn on the thyristor SCR1 is not applied, and SCR1 stops conducting. At the same time as this SCR1 turns off, resistor R1
A lower current I 4 flows, and charging of the lead acid battery 6 is switched to a lower current I 5 . Next, after the set time T1 , the oscillation circuit section 7 sends a reset signal for the set time.
If applied only during the time T 2 , thyristor SCR2
is off, so the current I 1 is connected to the diode D 1 and the resistor R
3. It flows into the gate of thyristor SCR1 through diode D2 and turns on thyristor SCR1 again. The explanation up to this point has been made regarding the overdischarge shown in FIG. In addition, C 1 and C 2 are capacitors, R1 to R6
is resistance.

ときに、第２図に示す正常充電時である急速充電
が開始される。 As described above, as the above operation is repeated with a set period T of T 1 +T 2 , the lead-acid battery 6 is gradually charged and the internal impedance is gradually reduced.
When the internal impedance becomes lower than the internal impedance during overdischarge, rapid charging, which is normal charging shown in FIG. 2, is started.

い。 Also, regarding the issue of full charging and overcharging, please refer to the second section.
The set cycle T of the oscillation circuit section 7 shown when fully charged in the figure.
If you set the cycle to be long enough, there is no need to worry about overcharging.

る。<Effects> The present invention detects the terminal voltage of the rechargeable battery using a voltage detection circuit, and when the battery voltage exceeds a predetermined voltage, the charging control element is cut off to stop charging the rechargeable battery or switch to low-current charging. In the switching charging device, the voltage detection circuit constantly holds the detection state, and the charging device is provided with an oscillation circuit, and the oscillation circuit periodically resets the holding state of the voltage detection circuit. Therefore, even if the internal impedance of a lead-acid battery becomes high due to overdischarge, rapid charging is possible.
