Transmission mounted electrical charging system with improved battery assembly

A system, comprising:

• a motive application having a prime mover, a load, and driveline mechanically interposed between the prime mover and the load;
• a motor/generator structured to selectively couple to the driveline;
• an electrical power storage system, the electrical power storage system comprising a plurality of batteries, wherein the plurality of batteries are grouped in a plurality of housing compartments, each housing compartment housing at least two of the plurality of batteries;
• a battery assembly that selectively electrically couples the plurality of batteries to the motor/generator, the battery assembly comprising:
• a power interface comprising a high voltage coupling positioned within a terminal one of the plurality of housing compartments;
• a motor drive converter (MDC) electrically interposed between the motor/generator and the high voltage coupling, wherein the MDC provides or receives DC power on the high voltage coupling side, and provides or receives AC power on a motor/generator side;
• and
• wherein the MDC is mounted on a sidewall of the terminal one of the plurality of housing compartments.
