Lithium Ion (Li-ion) battery Charging

Fast Charging: Most Li-ion battery applications need fast charging, like Electric Vehicles or mobile phones. Fast charging needs a higher level of voltage and current, which can hasten the charging process by supplying higher power per unit of time. However, Li-ion batteries are sensitive to voltage and current levels.

Lithium-Ion Cell Charging and Discharging During Life Cycle

During the CV float charging phase the charge current drops exponentially as the remaining charge accumulates in the cell. Full charge, or 100% SoC, is typically defined as when the charge current drops down to about 3 to 5% of the cell''s 1C charge rate. When charge current has dropped to this level, the charging is terminated.
