    What happens when a battery is charged with a power supply?

    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.

    What is the difference between constant current charging and constant voltage charging?

    Constant current charging is a method of continuously charging a rechargeable battery at a constant current to prevent overcurrent charge conditions. Constant voltage charging is a method of charging at a constant voltage to prevent overcharging. The charging current is initially high then gradually decreases.

    Can a battery be charged at a constant voltage?

    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.
