Multiple engine hybrid locomotive
First Claim
1. A hybrid power locomotive system comprising:
- a plurality of combustion engines;
a plurality of electric power generators each coupled to be driven by a corresponding one of the plurality of combustion engines;
a plurality of electric traction motors coupled in driving relationship to respective ones of a plurality of wheel-axle sets of the locomotive;
at least one traction motor drive connected for controlling power to electric traction motors;
an electric power storage device coupled to supply power to the traction motor drives;
an electric power controller arranged for coupling electric power from the power generators to the electric power storage device, the power controller sensing the available energy in the power storage device and the power demand from the traction drives for activating selected ones of the plurality of combustion engines for charging the power storage device.

Abstract
A hybrid power locomotive system has a plurality of combustion engines for driving a plurality of electric power generators that supply electric power to at least one traction battery. The battery is connected to supply power to a plurality of electric traction motors coupled in driving relationship to respective ones of a plurality of wheel-axle sets of the locomotive. At least one traction motor drive is connected for controlling power to the electric traction motors. An electric power controller is arranged for coupling electric power from the power generators to the battery and senses the available energy in the battery and the power demand from the traction drives for activating selected ones of the plurality of combustion engines for charging the battery.
