INTELLIGENT POWER ALLOCATION SYSTEMS ONBOARD HYBRID COMBINES AND ASSOCIATED METHODS

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.
