1. A modular battery pack system controllable to supply power to a motor load of an electric vehicle (EV), the modular battery pack system comprising:
a plurality of converter modules arranged in at least three cascades, each cascade comprising at least two converter modules coupled together, wherein the at least three cascades together output AC voltage signals of at least three different phases, and wherein each of the plurality of converter modules comprises:
a primary energy source;
a secondary energy source; and
switch circuitry; and
a control system coupled with and configured to control the switch circuitry of the plurality of converter modules to balance state of charge of each of the primary energy sources,
wherein, for each converter module of the plurality of converter modules, the switch circuitry is controllable by the control system to charge the primary or secondary energy source during regenerative braking of the EV.
