Title: CHARGING AN ACCUMULATOR
Abstract:
The invention relates to a method for charging an accumulator with terminals, at which a terminal voltage is applied, comprising the steps of: (a) charging the accumulator by means of a predetermined current or a predetermined electrical power until the terminal voltage has reached a predetermined first value; (b) determining a time-dependent drop in the terminal voltage of the accumulator with a changed charging current; (c) determining a second value based on the voltage loss, wherein the second value is greater than the first value; and (d) charging the accumulator by means of a predetermined current or a predetermined electrical power until the terminal voltage of the accumulator has reached the second value.
