Referring to fig. 1 to 3, in a preferred embodiment, the battery capacity repair circuit 30 includes a pulse signal generator 31, a pulse driving unit 32 and a constant current power supply 33, a controlled end of the pulse signal generator 31 is a controlled end of the battery capacity repair circuit 30, an output end of the pulse signal generator 31 is connected to a signal input end of the pulse driving unit 32, a power input end of the pulse driving unit 32 is connected to an output end of the constant current power supply 33, and an output end of the pulse driving unit 32 is an output end of the battery capacity repair circuit 30.
In this embodiment, the pulse signal generator 31 is configured to generate and output a pulse signal when receiving the control signal output by the voltage comparison circuit 20, where the pulse signal may be a pulse signal with a frequency of 8KHz to 9KHz and an amplitude of 2.5 to 3 times of the voltage of the battery cell 100, and the pulse driving unit 32 is configured to operate when receiving the pulse signal and output the constant current power supply 33 to the battery cell 100 to generate resonance with the battery cell 100, so as to eliminate lead sulfate crystals in the battery cell 100.
Referring to fig. 1 to 3, in the above embodiment, the pulse driving unit 32 includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R3, a fifth resistor R5, a MOS transistor Q4, a first triode Q1, a second triode Q2, a third triode Q3, a diode D1, and a first capacitor C1, wherein a first end of the first resistor R1 is a signal input end of the pulse driving unit 32 and is connected to a first end of the second resistor R2; a second terminal of the first resistor R1 is interconnected with a base of the first transistor Q1 and a first terminal of the third resistor R3; a collector of the first transistor Q1 is interconnected with a first terminal of the first capacitor C1 and a first terminal of the fourth resistor R3; the emitter of the first triode Q1 and the second end of the third resistor R3 are both grounded; a second end of the second resistor R2 is connected with an emitter of the second triode Q2; the collector of the second triode Q2 is connected with the base of the third triode Q3 through the fifth resistor R5; a collector of the third transistor Q3 is interconnected with a second terminal of the first capacitor C1, a second terminal of the fourth resistor R3 and a gate of the MOS transistor Q4; an emitter of the third triode Q3 is interconnected with the output end of the constant current power supply 33 and the drain of the MOS transistor Q4; the source of the MOS transistor Q4 is connected with the anode of the diode D1; the cathode of the diode D1 is the output of the pulse driving unit 32. The triode Q3 is connected with the power supply, and further comprises a zener diode ZD1, wherein the anode of the zener diode ZD1 is connected with the collector of the third triode Q3, and the cathode of the zener diode ZD1 is connected with the cathode of the third triode Q3.
In this embodiment, the pulse driving unit 32 triggers operation when receiving an oscillating pulse signal, i.e., a PWM signal, generated by the pulse signal generator 31, and triggers the first transistor Q1 to conduct and operate when the PWM is at a high level. The constant current source output by the constant current source 33 is output to the first triode Q1 through the fifth resistor R5, and at this time, the zener diode ZD1 provides a forward bias for the MOS transistor Q4, thereby triggering the MOS transistor Q4 to conduct. During the conduction period of the MOS transistor Q4, current flows through the diode D1 to charge the repaired battery cell 100.
When the oscillation pulse of the PWM signal is at a low level, the first transistor Q1 is turned off, and at this time, the second transistor Q2 makes the emitter of the second transistor Q2 at a low level through the second resistor R2, and the base thereof is at a high level to be in saturation conduction, so that the third transistor Q3 is in saturation conduction through the fourth resistor R3, the collector and the emitter of the third transistor Q3 short-circuit the gate-source of the MOS transistor Q4 to be turned off, and the current stops being charged to the repaired battery cell 100 through the diode D1. It can be understood that, by adjusting the period and duty cycle of the PWM, lead sulfate crystals formed between the two plates of the battery cell 100 are gradually decomposed and participate in the electrochemical reaction again under the action of the transformed pulse current, so as to recover the charge capacity of the battery cell 100.
It can be understood that, since the gate and the source of the MOS transistor Q4 mostly have a junction capacitor with a capacity of about 2000pF, in order to overcome the delay in the transition process time formed by the junction capacitor, which causes the MOS transistor Q4 to stay too long in the amplification state and increase the transistor loss of the MOS transistor Q4, the first capacitor C1 is connected in parallel with the fifth resistor R5 to shorten the conduction time of the MOS transistor Q4, so that the MOS transistor Q4 is turned on quickly.
