Abstract

Disclosed is a method for controlling the operating point (AP, AP1, AP2) of a battery (1), such as a lithium ion battery, a nickel metal hydride battery or a lithium polymer battery. The charging state (SoC1, SoC2) of the battery (1) is recorded as a state variable which determines the current operating point (AP1, AP2) of the battery (1). The current operating point (AP1, AP2) is set by a corresponding set value (SoCAP1, SoCAP2) for the charging state (SoC1, SoC2) which is continuously adjusted depending on the temperature (T) and/or on the age state (SoH) of the battery.
