HYBRID DRIVE SYSTEM FOR WORK MACHINE

A hybrid drive system for a work machine includes a drive system. The drive system includes an engine that generates a first energy supply. The drive system also includes a generator mechanically coupled with the engine to drive the generator. The drive system further includes a battery system that generates a second energy supply. The drive system includes a motor generator unit mechanically coupled with the generator to drive the generator. The motor generator unit is driven by the battery system. The hybrid drive system also includes a controller communicably coupled with the drive system. The controller is configured to control the drive system to direct, towards one or more traction motors of the work machine, a portion of at least one of the first energy supply via the generator and the second energy supply via the motor generator unit and the generator.
