1. A method for determining an estimated battery parameter vector indicative of a parameter of a battery at a first predetermined time, the method comprising:
- determining a first plurality of predicted battery parameter vectors that are indicative of the parameter of the battery and an uncertainty of the parameter of the battery at the first predetermined time;
determining a battery state vector having at least one value indicative of a battery state at the first predetermined time;
determining a second plurality of predicted battery output vectors that are indicative of at least one output variable of the battery and an uncertainty of the output variable at the first predetermined time based on the first plurality of predicted battery parameter vectors and the battery state vector;
determining a first battery output vector having at least one measured value of a battery output variable obtained at the first predetermined time;
determining a first estimated battery parameter vector indicative of the parameter of the battery at the first predetermined time based on the first plurality of predicted battery parameter vectors, the second plurality of predicted battery output vectors, and the first battery output vector; and
storing the first estimated battery parameter vector in a memory device.
