Electrification of off-highway equipment such as excavators presents unique challenges, particularly regarding system efficiency. Low efficiency necessitates larger battery packs to ensure full-day operation. Orion Research has identified that, in conventional excavators, up to 80% of hydraulic energy is lost as heat. This talk explores the transformative potential of a modular, decentralized electrohydraulic drivetrain to dramatically enhance efficiency, extend operational range and reduce battery size. We will share key insights gained from the development and testing of a prototype electrohydraulic system integrated with an excavator boom, highlighting its implications for the future of sustainable construction equipment.
