HYBRID POWER SYSTEM
First Claim
1. A hybrid power source, comprising:
- an electric power source;
a first hydraulic pump powered by the electric power source;
a hydrocarbon burning power source;
a second hydraulic pump powered by the hydrocarbon burning power source;
a hydraulic fluid output fed by a combined output from the first hydraulic pump and the second hydraulic pump; and
a controller for dynamically calculating hydraulic fluid requirements at the hydraulic fluid output as work is performed, the hydraulic fluid requirements being primarily provided by the first hydraulic pump powered by the electric power source and supplemented as directed by the controller by the second hydraulic pump powered by the hydrocarbon burning power source.

Abstract
A hybrid power source includes an electric power source, a first hydraulic pump powered by the electric power source, a hydrocarbon burning power source, and a second hydraulic pump powered by the hydrocarbon burning power source. A hydraulic fluid output is fed by a combined output from the first hydraulic pump and the second hydraulic pump. A controller is provided for dynamically calculating hydraulic fluid requirements at the hydraulic fluid output as work is performed. The hydraulic fluid requirements are primarily provided by the first hydraulic pump powered by the electric power source and supplemented, as directed by the controller, by the second hydraulic pump powered by the hydrocarbon burning power source.
