Challenges

A well implemented hybrid electric drivetrain compared to the standard mechanical one has the potential to decrease total fuel consumption and increase endurance by balancing energy savings. The hybrid electric technology utilizes an energy storage that complements the combustion engine to supply the required load with minimal stress on the system.

A combine harvester operates under highly variable load conditions. Accurately modelling the hybrid drivetrain requirements to meet these load conditions requires detailed data collection and ysis. Hybrid electric drivetrains combine mechanical electrical and sometimes hydraulic systems. Simulating the interaction between these systems requires precise modelling of both individual components and their combined behavior.
