What is the principle of lithium battery charger
The battery receives electrical energy from an external circuit and converts it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be recovered by charging and can be re-discharged to form a charge-discharge cycle. Generally, it is charged with a direct current (also asymmetrical alternating current or pulse current).
Under different circumstances, different charging methods such as constant current charging, constant voltage charging, floating charging, trickle charging, rapid charging or a combination of these methods are used.
According to the formula of power = voltage * current * time, when the power is fixed, the charging time can only be shortened by increasing the voltage or increasing the current.
