Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The method of claim 1 further including waiting until the ultra-capacitor has discharged to a nominal depletion voltage level to electrically isolate the voltage tolerant device and the ultra-capacitor from the voltage bus and electrically couple the voltage tolerant device directly to the ultra-capacitor and when the ultra-capacitor has discharged to the nominal depletion level, then 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. 3. The method of claim 1 including powering the voltage tolerant device directly from the ultra-capacitor until the ultra-capacitor has discharged to a minimum operating voltage level of the voltage tolerant device and once the ultra-capacitor has discharged to the minimum operating voltage level of the voltage tolerant device, then electrically re-coupling the voltage tolerant device to the voltage bus.
