    Abstract: The present disclosure pertains to motion-generating particles for desulfation of lead-acid batteries, lead-acid batteries including such motion-generating particles, and methods of making and using the same. For example, the present disclosure provides a lead-acid battery including one or more electroactive plates disposed within a casing; an electrolyte disposed within the casing and surrounding the electroactive plates; a plurality of ferromagnetic particles disposed with the electrolyte within the casing; and one or more electromagnets. The one or more electromagnets may be configured to direct a magnetic field towards the electrolyte to selectively cause movement of the plurality of ferromagnetic particles so as to agitate the electrolyte.

    Abstract: A state of charge (SOC) balancing system includes: first and second batteries; first and second capacitors; an SOC module configured to determine first and second SOCs of the first and second batteries, respectively; and a switching module configured to selectively, when the first SOC is greater than the second SOC: (i) electrically connect the first and second capacitors in parallel; (ii) electrically connect the first battery to the first and second capacitors while the first and second capacitors are electrically connected in parallel; (iii) electrically disconnect the first battery from the first and second capacitors; (iv) electrically connect the first and second capacitors in series; (v) electrically connect the second battery to the first and second capacitors while the first and second capacitors are electrically connected in series; and (vi) electrically disconnect the second battery from the first and second capacitors.

    Abstract: A battery system includes: two battery modules, each including three strings of battery cells that are configured to, at different times be: connected in series and to a first positive terminal via first ones of switches; connected in parallel and to a second positive terminal via second ones of the switches; and disconnected from both of the first and second positive terminals; and a switch control module configured to: determine state of charges (SOCs) of the strings, respectively; determine periods of phases, respectively, based on the SOCs; determine first periods for connecting ones of the strings in parallel; divide one of the phases into N equal length periods; selectively decrease N; when a number of the first periods that end closest to one of N period endings is at least a predetermined value, adjust the first periods to the respective closest ones of the N period endings.
