The future of mobile machine electrification Climate change, rising energy prices and advances in power electronics, storage and drive technology are rapidly advancing the electrification of mobile machines. However, the design of such systems remains complex – from the choice of drive concept (diesel-electric, hybrid, fully electric) to the optimal selection of components. 𝙊𝙪𝙧 𝙖𝙥𝙥𝙧𝙤𝙖𝙘𝙝: The analysis of power flows enables a systematic and open-ended pre-selection. This allows different powertrains to be compared and their optimal configuration to be determined – a decisive step towards economical and sustainable mobility. 𝘾𝙖𝙨𝙚 𝙨𝙩𝙪𝙙𝙮 𝙨𝙩𝙧𝙖𝙙𝙙𝙡𝙚 𝙘𝙖𝙧𝙧𝙞𝙚𝙧: A hybrid powertrain combines a diesel generator and battery, connected via a high-voltage DC link. The comparison with diesel-electric and fully electric alternatives shows: - Efficiency through stable DC link voltage (active rectifiers) - Influence of recuperation and losses - Reduced effort in detailed planning 𝙏𝙝𝙚 𝙢𝙚𝙩𝙝𝙤𝙙 𝙤𝙛𝙛𝙚𝙧𝙨: ☑ Optimisation without assumptions about operations management ☑ Integration into economic analyses ☑ Basis for dynamic operating strategies With this approach, we are creating a basis for the intelligent electrification of mobile machines that combines cost, efficiency and sustainability.
