Battery power supply. The output of the battery is pure DC, which is very clean. The voltage of the battery is neither possible nor needs to be designed very high. The chemical characteristics of the lithium battery determine that the output voltage of a battery cell can only be around 3.6V, so many batteries are in three-stage series mode, and 10.8V has become a very popular battery voltage. The nominal value of some batteries is slightly larger than the integer multiple of 3.6V, such as 3.7V or 11.2V, which is actually to protect the battery.
The situation of power supply is more complicated. First of all, it is necessary to further stabilize and filter the added voltage to ensure stable operation in the case of poor power supply performance. The stabilized voltage is divided into two parts, one is to power the notebook and the other is to charge the battery. The part that supplies power to the notebook is the same as that of the battery, The part to charge the battery can only be added to the battery cell through the battery charging control circuit. The control circuit can be very complex, so the power supply voltage must be greater than the battery cell voltage to have sufficient capacity to supply to each unit of the charging control circuit. Finally, the actual voltage applied to the cell will never be the nominal voltage of your power supply. Don't worry.Keywords:- Switching Power Supply
