New requirements and the challenges for electric drives systems in off-highway applications
With increasing requirements for zero emissions and CO2 reduction and in light of the current energy crisis, electrification has become one of the main development fields for all major OEMs. The off-highway market is highly diversified with many different requirements when compared to other market segments such as marine, factory automation or passenger car. The Rexroth electrification portfolio for off-highway machines has been developed based on the market's specific requirements and previous experience. The presentation will explain the key design principles and application-related performances of Rexroth’s eLION portfolio. Furthermore, it will show how a specific design has been developed to optimize the solutions for different vehicle functions such as drivetrain, implementation and accessories, in order to achieve maximum efficiency, noise reduction and power density. A practical use case will show the vehicle-specific implementation and performance of Rexroth’s scalable eLION solutions in a real, electrified, off-highway vehicle.
