Lithium-ion batteries explained
A Li-ion battery (a set of Li-ion cells in series) is charged in three stages: Constant Current, Balance (not required once a battery is balanced) and Constant Voltage. During the constant current phase, the charger applies a constant current to the battery at a steadily increasing voltage, until the voltage limit per cell is reached.
Lithium Ion (Li-ion) battery Charging
Lithium batteries necessitate a charging algorithm that upholds a constant current constant voltage (CCCV) during the charging process. In other words, a Li-Ion battery should be charged by a fixed current level, usually 1 to 1.5 amperes, until it hits its concluding voltage.
