System and method for providing auxiliary power by regeneration power management in mobile mining equipment
First Claim
1. A method for operating an ultracapacitor system used in a mining excavator powered by a power source, comprising:
- detecting whether a power from the power source is present; and
based on detecting that the power is not present;
measuring a voltage level of the ultracapacitor system;
comparing a measured voltage level with a minimum voltage level for the ultracapacitor system; and
based on comparing that the measured voltage level is more than the minimum voltage level, supplying auxiliary power from the ultracapacitor system to operate mining excavator systems.

Abstract
A method for operating an ultracapacitor system used in a mining excavator powered by an power source. The method includes detecting whether a power from the power source is present. Next, a voltage level of the ultracapacitor system is measured if the power is not present. The measured voltage level is then compared with a minimum voltage level for the ultracapacitor system. If the measured voltage level is more than the minimum voltage level, auxiliary power is supplied from the ultracapacitor system to operate mining excavator systems. The auxiliary power may be used to power electronic systems and components such as computers, displays, control systems, gas insulated switchgear and lighting systems.

20. A method for operating an ultracapacitor system used in a mining excavator powered by a power source, comprising:
-
monitoring a power draw from the power source of the mining excavator; and based on monitoring that the power draw is above a maximum power level; measuring a voltage level of the ultracapacitor system; comparing a measured voltage level with a minimum voltage level for the ultracapacitor system; and based on comparing that the measured voltage level is more than the minimum voltage level, supplying power from the power source and auxiliary power from the ultracapacitor system to operate the mining excavator.
