The voltage must be inscreasing (slowly) to get a constant curretn. Try charging a lithium cell witha buck converter and you''ll see whats going on. The voltage sets the current, but as the battery takes charges the current goes down so you keep raising the voltaage to keep the current constant.

Prior to turning the load off, it will send a pre-alarm signal indicating imminent low cell voltage. In the event of high cell voltage or low/high battery temperature, the Smart BMS CL 12/100 will send a "charge disconnect" signal to turn the charger(s) off. The alternator port controls and current limits the alternator.
