However, a battery pack with such a design typically encounter charge imbalance among its cells, which restricts the charging and discharging process . Positively, a lithium-ion pack can be outfitted with a battery management system (BMS) that supervises the batteries' smooth work and optimizes their operation .
When designing a single-cell Lithium-Ion charger, record the allowed maximum charge current and voltage of the battery in use. Then determine the voltage and maximum charge current of the power supply you want to use for charging. Usually, this will be five volts and between 500 mA and 900 mA (USB 2.0 and USB 3.0).
Moreover, a lithium-ion battery pack must not be overcharged, therefore requires monitoring during charging and necessitates a controller to perform efficient charging protocols [13, 23, 32, 143 - 147].
In fact, the internal charging mechanism of a lithium-ion battery is closely tied to the chemical reactions of the battery. Consequently, the chemical reaction mechanisms, such as internal potential, the polarization of the battery, and the alteration of lithium-ion concentration, have a significant role in the charging process.
Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.
Typically, PMICs charge LiPo and Lithium-Ion batteries using the CC-CV method. The battery gets charged with a constant current until the cell reaches its maximum voltage. From then on, the charger gradually decreases the charge current until the battery is fully charged. Modern charge ICs apply a few more steps to the process to increase safety.
