Abstract (en)

[origin: WO2011124411A2] The invention relates to a method for charging a battery (2), in particular a lithium ion battery, comprising the following steps: charging the battery (2) with a constant charging current (IL) in a first phase (I), charging the battery (2) with a constant charging voltage (UL) in a subsequent second phase (II), terminating the charging in accordance with a predefinable limit value of the charging current (IL) in the second phase (II). The following steps are implemented: comparing a guide voltage (UF) which is predefined for adjusting the constant voltage with a least one stored switch-off value which is determined in accordance with the limit value, and terminating the charging when the guide voltage (UF) reaches the switch-off value. The invention further relates to a device for charging a battery.
