Classification: CPC B  Y | IPC B

Claim 12:
13. A system for ascertaining a state of charge of a battery of a motor vehicle, the system comprising:
a plurality of motor vehicles; and
a central unit configured to:
receive operating variables of a battery of a corresponding motor vehicle of the plurality of motor vehicles;
receive a calculated state of charge from the corresponding motor vehicle calculated 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;
ascertain a reference state of charge using a reference state-of-charge model depending on the received operating variables, and
perform a correction of the at least one battery model parameter depending on a difference between the 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.
