ABSTRACT:
Thus, according to the invention, for monitoring and/or controlling or automatically controlling the voltage of at least one group of cells in a cell compound of an energy storage device, particularly an energy storage device in an onboard power supply system of a motor vehicle, a data communication is carried out between a central logic and a cell group logic by way of the rail line connecting the latter, in which case voltage levels exist between an idle level situated at or above a maximal voltage level, up to which the cell group logic exchanges energy with the rail line for charging or discharging the cell group, and a data level situated above the idle level.
