Claim 12:
13. A method of supplying power from a modular battery pack system of an electric vehicle (EV), the method comprising:
controlling a plurality of converter module array to output multi-phase voltage signals to a multi-phase motor of the EV, wherein each array comprises a plurality of 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 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, and wherein:
wherein for 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, 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, the controlling comprising:
outputting information from a master control device to a plurality of local control devices;

generating, by the plurality of local control devices, pulse width modulated signals from the information received from the master control device; and
controlling each arrayed converter module of the arrays by the pulse width modulated signal to selectively output the positive DC output voltage, zero output voltage, or negative DC output voltage; and
controlling interconnection modules 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.
