A vehicle, system and method of operating a battery having a plurality of modules, each module having a plurality of strings. The vehicle includes the battery. A processor operates the plurality of modules in a first phase of a mode of operation, calculates a model-predicted path vector for the first phase based on a time for reducing a difference between states of charges of the plurality of strings, selects between the model-predicted path vector and a default path vector based on an operating parameter of the battery, and switches operation of the plurality of modules from the first phase to a second phase using the selected one of the model-predicted path vector and the default path vector.
