The system includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded for automated management of a set of parameters related to the battery pack, subject to a plurality of constraints. The power module is adapted to deliver a second current for powering a load in the electric vehicle. Operation of the electric vehicle is controlled based in part on the set of parameters.

Abstract: Simultaneous parallel charging of a first and second electrical energy storage devices coupled to a charge source is carried out by directly coupling the charge source to one of the first ESD and the second ESD and through a DC to DC converter to the other of the first ESD and the second ESD. The charge source provides a current that is allocated to the two ESDs by controlling the DC to DC converter. Priority of charging may be given to either ESD.
