The fast charge (constant current) and constant voltage charging are the most important stages during a recharge process. Most Li-ion batteries have a fully charged voltage of 4.1 V or 4.2 V. The battery is first charged with a constant current of 1C until the battery voltage reaches 4.1 V or 4.2 V.
Advantages of the MCU-controlled charging method include safe charging, time efficiency, and low cost. Battery capacity (C), expressed in milliamp-hours (mAh), is a measure of battery life between charges. Battery current has the units of C-rate.
The problem with charging and using a Li-ion battery at the same time is that end of charge is not properly detected. The MCP73831 uses the current level at the end of the constant voltage stage for charge termination. Aha that makes sense, thanks for clearing that out. I think i will leave the schematic as it is and not remove the switch.
The slow charge stage is rarely used during the charging process of a Li-ion battery. The fast charge (constant current) and constant voltage charging are the most important stages during a recharge process. Most Li-ion batteries have a fully charged voltage of 4.1 V or 4.2 V.
