1. A modular energy system of an electric vehicle (EV), comprising:
a first subsystem configured to supply power to a first motor of the EV, the first subsystem comprising three arrays each comprising at least two first modules electrically connected together to output an AC voltage signal comprising a superposition of output voltages from each of the at least two first modules, wherein each of the first modules comprises an energy source and a converter;
a second subsystem configured to supply power to a second motor of the EV, the second subsystem comprising three arrays each comprising at least two second modules electrically connected together to output an AC voltage signal comprising a superposition of output voltages from each of the at least two second modules, wherein each of the second modules comprises an energy source and a converter; and
a plurality of switches configured to selectively connect the first and second subsystems for charging, wherein a nominal output voltage of the first subsystem is greater than a nominal output voltage of the second subsystem.
