Claim 0:
1. A method for operating a system for ascertaining a state of charge of a battery of a motor vehicle, comprising:
providing operating variables of the battery;
providing a calculated state of charge in the motor vehicle using a state-of-charge model that indicates the calculated state of charge depending on at least one battery model parameter of the state-of-charge model for the battery;
ascertaining a reference state of charge using a reference state-of-charge model based on the operating variables; and
performing a correction of the at least one battery model parameter depending on a difference between the ascertained reference state of charge and the calculated state of charge in order to adapt the calculated state of charge to the reference state of charge.
