SYSTEM AND METHOD FOR POSTERIORI ADAPTATION OF A STATE OF CHARGE MODEL IN A BATTERY

摘要

A method for estimating a state of charge in a battery includes identifying a first state of charge in the battery at a first time, identifying the first state of charge in the battery at a second time after operation of the battery, identifying an estimated state of charge at the second time with reference to a model having a plurality of model parameters, modifying at least one of the plurality of model parameters with reference to an error between the estimated state of charge and the first state of charge, and generating an output corresponding to an estimate of the state of charge of the battery using the model with the at least one modified parameter while operating the battery in the at least one operating mode after the second time.
