First controlling switch 56, one end of the first controlling switch 56 couples with the first negative pole 5412 of first interface 541, another
End and the coupling of the first mainboard (not shown)；First control end 561 of the first controlling switch 56 and the 3rd pin of the first chip 52
523 couplings；First chip 52 detects the voltage of battery core 54 by the first pin 521 and second pin 522, and by voltage and first
Threshold range compares, the voltage of the 3rd pin 523 of change, and then controls the break-make of the first controlling switch 56, so as to control battery core
The charge and discharge process of 54 first interface 541.
Specifically, such as first threshold scope value is (2.5-4.5V), when the voltage of battery core 54 is in first threshold model
When enclosing interior, the first chip 52 controls the voltage of the 3rd pin 523 for high voltage, and the first interface 541 of battery core 54 can be carried out normally
Charge and discharge process；When the voltage that the first chip 52 detects battery core 54 is 2V, less than the minimum voltage of first threshold scope,
I.e. current battery core 54 was in voltage status of loweing, and the first chip 52 controls the voltage of the 3rd pin 523 for low-voltage, the first control
Switch 56 disconnects, and then disconnects the first discharge path, but now the first charge path is also disconnected；When the first chip 52 is detected
When the voltage of battery core 54 is 6V, i.e., higher than the maximum voltage of first threshold scope, now battery core 54 should be in the state for overcharging,
First chip 52 controls the first controlling switch 56 to disconnect, and then causes the first charge path of disconnection of battery core 54, but now overcharge
Voltage cannot discharge, and still can damage battery core 54.
Please continue to refer to Fig. 5, the phenomenon for overcharging occurs for battery core 54 above, the first protection circuit 50a increases as follows

End, the conducting direction of the first diode 51 is the direction of the first negative pole 5412 from mainboard (not shown) to first interface 541, second
The conducting direction of diode 53 is opposite with the conducting direction of the first diode 51.
Specifically, when voltage is in the range of first threshold, for example, the first chip 52 detects now chip voltage being
4V, in first threshold scope (2.5V-4.5V), the first chip 52 controls the 3rd pin 523 and the 4th pin 524 to export electricity high
Flat, the first controlling switch 56 and the second controlling switch 58 are turned on, and first interface 541 can be normally carried out discharge process；Work as voltage
During more than first threshold scope, for example, it is 6V that the first chip 52 detects now chip voltage, more than first threshold scope
(2.5V-4.5V), i.e., now battery core is in the state for overcharging, the control output low level of the 4th pin 524 of the first chip 52, the 3rd
Pin 523 export high level, and then cause the first controlling switch 56 turn on, the second controlling switch 58 disconnects, first interface 541 this
Shi Wufa is charged by the first protection circuit 50a, but now first interface 541 can be by the two ends of the second controlling switch 58
Second diode 55 is discharged, and bleeds off the voltage that battery core 54 is overcharged；When voltage is less than first threshold scope, for example, first
It is 2V that chip 52 detects now chip voltage, and less than first threshold scope (2.5V-4.5V), i.e., now battery core was in what is put
State, the control output high level of the 4th pin 524 of the first chip 52, the output low level of the 3rd pin 523, and then cause the first control
System switch 56 is disconnected, and the second controlling switch 58 is turned on；First interface 541 can not be discharged, but can be by the first diode
51 pairs of battery cores charge.
In some cases, battery core 54 may there is also voltage normally, but discharge path is because of situations such as short circuit, occurs
Electric current is excessive.Therefore, please continue to refer to Fig. 5, the first chip 52 in above-described embodiment also includes the 9th pin 525, and the 9th draws
Pin 525 is coupled between the first mainboard (not shown) and the first negative pole 5412, the first electric current for measuring the first discharge path；When
First electric current is more than the 3rd threshold value, the pin of the first chip controls the 3rd and/or the 4th pin output low level, the first discharge path
Disconnect, so as to protect battery core 54.
Please continue to refer to Fig. 5, the second protection circuit 55a, second are provided with the second protection board 55 coupled with battery core 54
The design of protection circuit 55a is identical with the first protection circuit 50a, and control principle is also identical, will not be repeated here.In addition,
In actual use, can also be introduced in above-mentioned first protection circuit 50a and the second protection circuit 55a some resistance, electric capacity,
