Abstract
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, includes 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 and electrically coupling the voltage tolerant device directly to the ultra-capacitor. In an aspect, the method includes electrically isolating the voltage tolerant device and the ultra-capacitor from the voltage bus and electrically coupling the voltage tolerant device directly to the ultra-capacitor when the ultra-capacitor has discharged to a nominal depletion voltage level.
