In this thesis, we would like to present the principle of battery control board work, manufacture assembly for notebook battery. We had design different testing conditions that vary with charging voltage and current to assess charging time, battery performance and battery cycle life. However, the optimization of battery charging is base on Charging Temperature, Charging Voltage, Charging Current and Discharging Current, those factors will impact Battery charging and discharging efficient and improve Battery cycle life. Between CC-CV charging mode and Step charging mode, the different is we can get better Battery optimize and it can delay degradation for Battery.
