Claim 0:
1. A modular battery pack system controllable to supply power to a multi-phase motor of an electric vehicle (EV), the modular battery pack system comprising:
a plurality of interconnection modules, each interconnection module comprising a plurality of respective ports, a respective battery, and respective switch circuitry, wherein the respective batteries are electrically coupled in parallel; and
a plurality of converter module arrays, each array comprising arrayed converter modules electrically coupled together to output an AC voltage signal comprising a superposition of output voltages from each of the arrayed converter modules, wherein each of the converter module arrays is configured to output an AC voltage waveform having a different phase angle for the multi-phase motor, and wherein each of the arrayed converter modules comprises an energy source and is controllable to selectively output a positive DC output voltage, zero output voltage, or negative DC output voltage from the energy source;
wherein each interconnection module has at least one respective port connected to a separate converter module array, and the respective switch circuitry of the plurality of interconnection modules are configured to selectively connect the batteries of the interconnection modules to the converter module arrays to balance states of charge across the plurality of converter module arrays;
a plurality of local control devices configured to output switch signals to each of the arrayed converter modules of each array and the interconnection modules;
a master control device communicatively coupled with the plurality of local control devices, the master control device configured to output information to the plurality of local control devices; and
wherein the plurality of local control devices are configured to generate pulse width modulated switch signals based on the information received from the master control device.
