E-AXLE-R8R Next-generation E-AXLE Responding to the 8 customer Requirements for ACCELERATED powertrain ELECTRIFICATION

电动总成的高成本限制了电动汽车和混合动力汽车的发展速度。该项目旨在提供一种完全集成的e轴(电力电子、电机和变速箱)，它将超过英国汽车委员会2025年这些技术的成本目标，并适合英国制造。这将同时加快电动汽车的普及速度，减少对政府补贴的要求，并增加英国熟练制造业的工作岗位数量。通过在电机中使用新型聚合物粘合转子和超低成本卷曲定子结构，e轴将超过2025年的成本目标。电力电子产品将把优化的功率级布局与新颖的控制和冷却技术结合起来。将使用先进的系统级优化工具来确定e轴的尺寸，并确保为应用选择最佳的变速箱拓扑。E轴将由突破性的电动汽车OEM底特律电气在骡车上进行演示。

"The high-cost of electric powertrains is limiting the speed of uptake of electric and hybrid-electric vehicles.This project aims to deliver a fully-integrated e-axle (power electronics, electrical machine and gearbox) which will beat UK Automotive Council 2025 cost targets for these technologies and be suitable for UK manufacture. This will simultaneously increase the speed of uptake of electric vehicles, reduce the requirement for government subsidy and increase the number of skilled manufacturing jobs in the UK.The e-axle will beat 2025 cost targets by utilising a novel polymer-bonded rotor and ultra-low-cost roll-up stator construction in the electrical machine. The power electronics will combine an optimised power stage layout with novel control and cooling techniques. Advanced system-level optimisation tools will be used to size the e-axle and ensure the best gearbox topology is selected for the application. The e-axle will be demonstrated in a mule vehicle by break-through electric vehicle OEM Detroit Electric."
