1. A method of performing a first start of an internal combustion engine of a hybrid electro-mechanical vehicle having a motor/generator powerable by a high voltage battery characterized by a first voltage and a staffer motor for starting the internal combustion engine powerable by a low voltage battery characterized by a second voltage less than the first voltage, the method comprising:

  • activating an auxiliary power module prior to the engine starting to thereby direct power stored in the high voltage battery through the auxiliary power module at the second voltage to assist the low voltage battery in powering the starter motor with power at the second voltage; and

    wherein a controller carrying out said activating is powerable by the low voltage battery at the second voltage.
