Abstract
The present invention relates to a method and to a battery management system which are suitable for determining an open-circuit voltage profile () of a vehicle battery, dependent on a state of charge, in a vehicle. In this context, the following occur: complete discharging (S) of the vehicle battery by vehicle-internal loads of the vehicle, sensing (S) of a first sensed, state-of-charge-dependent voltage profile () during the discharging (S) of the vehicle battery, complete charging (S) of the vehicle battery by a charging device, sensing (S) of a second sensed state-of-charge-dependent voltage profile () during the charging (S) of the vehicle battery, and determination (S) of the state-of-charge-dependent open-circuit voltage profile () by means of a weighted interpolation of the first sensed voltage profile () and of the second sensed voltage profile ().
