In Constant Voltage state, the same voltage is applied at a constant rate by the charger circuit at the terminals of the battery. Trying to charge the battery by applying a higher voltage than this may charge the battery fast but it reduces the battery life.
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.
By Irena Zhuravchak and Volodymyr Ilchuk | Tuesday, June 27, 2023 Charging a battery using the constant-current/constant-voltage (CC/CV) method involves using the constant current in the initial state of charging and then switching to constant voltage in the later stages of charging, when the battery reaches the set charge level.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Constant current/constant voltage is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.
When the discharged battery (at 15V) is connected to the power supply, the battery will start to charge at the pre-set constant current level. The current will remain constant until the voltage rises to 28V. At this point the power supply will transition to constant voltage mode and the current will decay to zero when the battery is fully charged.
Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage. The current will then taper down to a minimum value once that voltage level is reached.

CCCV charging is a typical method of charging rechargeable batteries such as li-ion. Operation switches between CC charging, which charges with a constant current, and CV that charges at a constant voltage, depending on the voltage of the rechargeable battery. This is one of the methods used in ROHM charge control ICs.

Same applies to the constant current power supply. It will push constant current into battery until battery voltage rises high enough so the supply can''t output constant current any more.
