Presentation

High-efficiency electrohydraulic architectures for off-highway applications

Improving the efficiency of hydraulic architectures is key to the electrification of off-highway vehicles. Hydraulic systems offer robustness and power density at low cost but have primarily been developed for ICEs. Straightforward conversion to an electric power source leads to inefficient energy utilization. Improving system efficiency is essential to overcoming the challenge of achieving a full day’s battery-powered operation. At Orion Research, we have undertaken the complete instrumentation of a 5-tonne excavator to characterize and evaluate system losses. In combination with simulation, this has enabled us to develop novel solutions and effective implementation of a semi-distributed electrohydraulic architecture.
