ABSTRACT:
A method for charging an electric storage cell, in particular a lead acid battery, as the starter battery in a motor vehicle, involves the generator voltage being controlled, using the charge state of the accumulator as a controlled variable, the charge state being derived from a measurement of the no-load voltage of the storage cell at the instant of the zero crossing of the current flowing in the storage cell. The measurement of the no-load voltage is carried out within a period of from 0.1 ms to 1 ms after a zero crossing of the current in the storage cell.
