Abstract: Embodiments of an intelligent hybrid powertrain system include an engine, a controller architecture, and an electric drive subsystem having a battery supply and a motor/generator. The controller architecture is configured to: (i) monitor a current state of charge (SoC) of the battery supply when the combine harvester engages in a combine harvest cycle having a tank fill phase and a tank unload phase; (ii) during the tank fill phase, operate the motor/generator to supplement the engine power output and regulate a rate of battery discharge to prevent the current SoC of the battery supply from decreasing below a lower predetermined SoC threshold prior to completion of the tank fill phase; and (iii) during the tank unload phase, operate the motor/generator to charge the battery supply until the current SoC of the battery supply is equal to or greater than a first upper predetermined SoC threshold.

Abstract: Embodiments of an intelligent power allocation system include a ground traction undercarriage controllable to propel a hybrid combine over terrain, a separator device configured to separate grain from other crop material ingested by the hybrid combine, a mechanical powertrain including an internal combustion engine, and an electric drive subsystem containing a rechargeable battery pack and a motor/generator (M/G). A controller architecture is configured to monitor a current separator load placed on the hybrid combine when driving movement of the separator device during active harvesting. The controller architecture further selectively places the intelligent power allocation system in a separator power splitting mode in which the M/G and the internal combustion engine concurrently drive movement of the separator device based, at least in part, on whether the current separator load exceeds an upper load threshold.
