Constant voltage charging is generally safer than constant current charging, as it will not cause the battery to overheat or explode. However, constant voltage charging can take longer to fully charge the battery when compared to constant current charging.
However (quoting you): charging at a constant voltage (say 4.2V) so long as the maximum current is limited to a reasonable value for the cell means you will have constant current charger till your cell is at ~95%. Up to this point the voltage across the battery will be less than 4.2V if you measure it.
Constant voltage charging is a charging method that uses a fixed voltage to charge the battery. This method is ideal for charging batteries that are already partially charged, as it can provide a lower current to the battery as it approaches full charge.
This method is ideal for charging batteries that are already partially charged, as it can provide a lower current to the battery as it approaches full charge. Constant voltage charging is generally safer than constant current charging, as it will not cause the battery to overheat or explode.
Additionally, constant current charging can be inefficient if the battery is already partially charged, as it will continue to provide a high current even if the battery is nearly full. Constant voltage charging is a charging method that uses a fixed voltage to charge the battery.
Importantly, the DC power source ensures that it does not exceed the maximum battery voltage limit during this adjustment. The relationship between the charging voltage and the battery charging current limit can be expressed by the formula: Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm.
