The application for the patent was published on June 19, 2026, under issue no. 25/2026.

Abstract: A Lead-Acid Battery Management System (BMS) and a method for operating a BMS for a battery system comprising a plurality of groups of at least one lead acid battery, the battery management system comprising: at least one control device configured to electrically integrate and segregate each of the batteries from the string, and a controller configured to control the control device to independently control the charging and discharging of each of the batteries. In some cases the controller is configured to determine an input power available to charge the battery system, determine, based on the determined input power, that at least one of the groups of batteries can charge above a charging threshold; and selectively charge at least one of the groups of at least one battery. In some cases the BMS is configured overcharge the batteries independently. In some cases the BMS is configured to modify the discharging of the at least one battery based in a determined charge characteristic.
