The circuit is mainly composed of the special integrated circuit dw01 for lithium battery protection, charge and discharge control mosfet1 (including two n-channel MOSFETs). The single lithium battery is connected between B + and B -, and the output voltage of the battery pack is from P + and P -. During charging, the output voltage of the charger is connected between P + and P -, and the current is from P + to B + and B - of the single battery, and then through charging control MOSFET to p -. In the charging process, when the voltage of the single battery exceeds 4.35v, the OC pin output signal of the special integrated circuit dw01 turns off the charge control MOSFET, and the lithium battery stops charging immediately, so as to prevent the damage of the lithium battery due to overcharge. In the discharge process, when the voltage of the single battery drops to 2.30v, the OD pin of dw01 outputs a signal to turn off the discharge control MOSFET, and the lithium battery immediately stops discharging, so as to prevent the lithium battery from being damaged due to over discharge. The CS pin of dw01 is the current detection pin. When the output is short circuited, the conduction voltage drop of the charge discharge control MOSFET increases sharply, and the CS pin is the current detection pin The output signal of dw01 makes the charge and discharge control MOSFET turn off quickly, so as to realize the over-current or short-circuit protection.

What are the advantages of lithium polymer battery

1.   there is no problem of battery leakage, and the battery does not contain liquid electrolyte inside, using colloidal solid.    2.   can be made into thin battery: with the capacity of 3.6v400mah, its thickness can be as thin as 0.5mm.   3.   the battery can be designed into many shapes   3

4. Bendable deformation of battery: the maximum bendable deformation of polymer battery is about 900

5.   single high voltage can be made: the battery with liquid electrolyte can only obtain high voltage in series with several batteries, and the polymer battery can be made into multi-layer combination in a single cell to achieve high voltage because it has no liquid.
