Constant voltage charging is a method of charging at a constant voltage to prevent overcharging. The charging current is initially high then gradually decreases. A constant charging method characterized by high initial current when the voltage is low, then decreasing current as the voltage gradually increases.
During the constant voltage mode, the charging current starts to decrease. When the charging current drops to a predefined minimum current value (e.g., 0.05 C), the charging process concludes, indicating the battery is fully charged (e.g., battery state of charge is 100%).
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries.
The charging switches to constant voltage (4.2 V) when the battery’s internal voltage exceeds or equals 4.2 V. The process concludes when the charging current drops below 0.05 C. Figure 13 and Figure 14 illustrate the charging profile and flowchart of the Type III CC-CV charging method.
There are three common methods of charging a battery: constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit. Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.

Constant voltage charging is when the voltage applied to the battery remains constant while the current draw decreases. This happens right before the battery is fully charged so that overcharging does not occur. Trickle charging happens after a lithium-ion battery has been fully charged and it just gives it a small amount of current so that self-discharge does not happen.
The Constant Current (CC) scheme charges with a low, constant current to obtain full charge only at the end. Constant Voltage (CV) scheme has to maintain a constant voltage in order to charge the batteries and prolong its life. Hence the objective of this work is to integrate both CC and CV charging circuit for a lithium-ion battery. To prolong ...

You can''t have a constant current and a constant voltage at the same time. (Well, It can only happen if the load is constant.) This is because the voltage changes as the battery charges.
