When the core voltage is between 2.5V to 4.3V, the DW01 's 1th and 3rd feet are output high (equal to the supply voltage) and the second leg voltage is 0V. At this time DW01 1th feet, 3rd foot voltage will be added to 8205A 5th, 4 feet, 8205A two of the electronic switch because of its G pole received from the DW01 voltage, it is in the conduction state, that is, two electronic switches are in open state. At this time, the cathode of the core and the P-end of the protective plate are connected directly, and the protection plate has voltage output.Lithium Electric Scooters
When the core is discharged through an external load, the voltage of the core will slowly decrease, while the DW01 internal will monitor the core voltage through the R1 resistor in real time. When the core voltage drops to about 2.3V DW01 will think that the core voltage is already in the Over-voltage state, then immediately disconnect the output voltage of the 1th foot, so that the 1th foot voltage into 0V, 8205A in the switch tube for the 5th foot without voltage and closed. At this time, the B-P of the core is in a disconnected state from that of the protective plate.Lithium Electric Scooters
That is, the electric core of the discharge circuit is cut off, the core will stop discharging. The protective plate is in the discharge state and remains. After the p and p of the protective Plate are charged to the voltage, DW01 by B-detection of the charge voltage immediately after the discharge state, again in the 1th foot output high voltage, so that 8205A in the discharge control tube conduction, that is, the B-and protection of the core of the P-and again, the electric core by the charger directly charged.Lithium Electric Scooters
When the battery is properly charged through the charger, with the increase of charging time, the voltage of the core will be higher, when the core voltage increases to 4.4V, DW01 will think that the core voltage is already in the charging voltage state, then immediately disconnect the 3rd leg of the output voltage, so that the 3rd foot voltage into 0V, The switch tube in 8205A is closed because of no voltage on the 4th leg. At this time, the B-P of the core is in a disconnected state from that of the protective plate. That is, the charging circuit of the electric core is cut off and the battery will stop charging. The protection board is in the overcharge state and has been maintained.Lithium Electric Scooters
