1. A method of utilizing charge from an ultra-capacitor in a vehicle electrical system having a voltage bus and having one or more voltage tolerant devices, comprising:

  • when one of the voltage tolerant devices is turned on, electrically isolating that voltage tolerant device from the voltage bus, electrically isolating the ultra-capacitor from the voltage bus, electrically coupling the voltage tolerant device directly to the ultra-capacitor, and powering the voltage tolerant device directly from the ultra-capacitor including after the ultra-capacitor has discharged below a nominal voltage of the voltage bus.
