Charging and Discharging Definition: Charging is the process of restoring a battery''s energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions. Oxidation Reaction: Oxidation happens at the anode, where the material loses electrons.
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). At this stage, estimating SoC (state of charge) based on the battery voltage would mean that the battery is fully charged. The battery

This example was tested on a Speedgoat Performance real-time target machine with an Intel® 3.5 GHz i7 multi-core CPU. This model can run in real time with a step size of 50 microseconds.
Discharging a lithium-ion battery is the process of releasing the battery’s stored electrical energy to power a device or perform other functions. The type and size of the battery, the age of the battery, and the temperature are all factors that can influence the discharging process.
When a battery is connected to a charging device, such as a charger or a power bank, the charging process begins. The charging device charges the battery by causing the lithium ions in the positive electrode to move through the separator and into the negative electrode.
