Battery charging current reference

If the upper limit is exceeded, the current reference is limited to the maximum continuous battery current, whereas if the current reference has fallen below the lower limit and is thus maintained for a predefined time interval (20 s herein), this is indicative of a fully charged battery; therefore, the charging process is stopped.

Battery Charging Stages & Battery Charging Procedure

When these batteries are being charged, they go through four distinct stages: pre-charging, constant current charging, constant voltage charging, and trickle charging. Pre-charging is when the battery is initially plugged in and is drawing a very small amount of current in order to get the chemical reaction started within the battery.
