Battery management unit and method

Abstract

A battery management unit and method are disclosed. The battery management unit includes a sensor, a first battery model, a second battery model, and a processor. The sensor measures a voltage of a battery. The first battery model and the second battery model are to estimate different characteristics of the battery based on a measurement voltage. The processor obtains a first terminal voltage corresponding to the measurement voltage based on the first battery model, obtains a second terminal voltage corresponding to the measurement voltage based on the second battery model, and fuses the first terminal voltage and the second terminal voltage to determine a final terminal voltage of battery.

Dependencies are inferred from the claim text.
