BU-409: Charging Lithium-ion
This excellent article describes that dangerous overcharging is likely if we charge a 3.7V lithium ion cell at 4.2V and forget - in the constant voltage phase - to switch off charging after the current has dropped to one tenth of the initial value. But will this overcharging ...
Understanding Charge-Discharge Curves of Li-ion Cells
When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current. The charging current keeps coming down until it reaches below 0.05C. The battery reaches full charge voltage some time after the CV mode starts (as soon as one of the cells reaches its full charge voltage).
Charging control strategies for lithium‐ion battery packs: Review …
This charging process is then repeated until the full range of preset charging currents is reached. At each stage, the charging current falls gradually, preventing the battery from reaching the maximum limit of cut-off voltage too quickly. Besides the upper cut-off voltage, the shifting condition may also be set based on the …
