Abstract

A method is described for charging an accumulator having terminals at which a terminal voltage is applied. The method includes the following steps: (a) charging the accumulator using a predefined current or a predefined electrical power until the terminal voltage has reached a predefined first value; (b) determining a time-dependent drop in the terminal voltage of the accumulator at a reduced charge current; (c) determining a second value on the basis of the voltage loss, the second value being greater than the first value; and (d) charging the accumulator using a predefined current or a predefined electrical power until the terminal voltage of the accumulator has reached the second value.
