Abstract
A battery controller with monitoring logic for a model-based battery control of a battery performs battery current characterizing, parameter and state variable abnormality detection, and bound checking of error signals between measured and predicted output variables to generate an output. Switching between closed-loop operation (i.e., the model-based battery control) and open-loop operation (i.e., a traditional battery control) is done based on the output of the monitoring logic such that closed-loop stability and performance are reasonably guaranteed.
