EPIC (Electric Powertrain Integration for heavy Commercial vehicles) Project

EPIC项目是一个工业制造项目，为高达44吨GVW的商用车开发下一代集成电动动力系统（IEPT）。该财团由美立特、丹佛斯和伊莱克特拉组成。美瑞特在全球车轴和驱动系统工程领域处于领先地位，丹佛斯开发先进的电动机，而伊莱克特则专注于电动汽车集成。IEPT产品将包括一个集成SiC逆变器的单一电机，集成多速变速箱和差速器，以及为再生制动优化的基础制动器。动力系统通常适用于4x2或6x2商用车配置，但也支持其他配置，包括非公路、建筑和职业车辆。目前的驱动系统采用遥控安装电机，但仍然依赖于传动系统和传统的车轴。现有的轮轴依靠两个电机来实现所需的扭矩和动力，这增加了成本和复杂性。EPIC解决方案消除了传动系统和对多个电机的需求。由于传动系统的存在，较短轴距的欧盟卡车尤其无法利用框架轨道之间的区域，这限制了电池存储，从而限制了车辆的范围。有了这种新颖的动力系统，空间变得触手可及。动力总成将与现有车轴共享相同的底盘安装，以便于车辆应用。而其完全集成的性质提供了远程安装解决方案的进一步好处，包括：*增加了电池和/或氢气在框架轨道之间的存储*大约363公斤的重量节省*更小的包装外壳*高模块化广泛的应用范围*增加范围和/或有效载荷*更高的整体效率我们计划到2025年每年消除420万吨二氧化碳。动力系统的高效率、重量和空间的减少将提高续航里程和/或有效载荷，从而有可能在这个备受批评的领域减少二氧化碳排放。这种新型动力系统的广泛优势将同样加速电池电动、燃料电池和增程混合动力商用车的采用。为了实现该项目，美立特将在科姆布兰建立一个卓越中心，扩大测试设施和研发团队。丹佛斯将在爱丁堡附近的一个低碳创新中心开发和组装带有集成逆变器的电机。Electra将组装车辆，并计划在英国的测试轨道和公共道路上完成耐久性和现场运行。这些车辆还将用于向全球主要汽车制造商、车队和其他潜在终端用户演示这项技术。英国项目总支出为8200万英镑，预计将在英国创造189个就业岗位，同时保护约500个就业岗位。

Project EPIC is an industrial manufacturing project developing a next-generation integrated electric powertrain (IEPT) for commercial vehicles up to 44 tonne GVW. The consortium comprises Meritor, Danfoss, and Electra. Meritor leads in global axle and drive system engineering, Danfoss develops advanced electric motors, and Electra specialises in electric vehicle integration.The IEPT product will consist of a single motor with an integrated SiC inverter, integral multispeed gearbox and differential, and foundation brakes optimised for regenerative braking. The powertrain will typically suit 4x2 or 6x2 commercial vehicle configurations but other configurations including off-highway, construction and vocational vehicles are also supported.Drive systems exist today with remote mount motors but still rely on drivelines and traditional axles. Existing eAxles rely on two motors to achieve the required torque and power, which adds cost and complexity. The EPIC solution eliminates the driveline and need for multiple motors. Shorter wheelbase EU trucks are especially unable to utilise the area between the frame rails due to the driveline presence, which limits battery storage thereby limiting the vehicle range. With this novel powertrain, the space becomes accessible.The powertrain will share the same chassis mounting as existing axles allowing for easy vehicle application, while its fully integrated nature offers further benefits over remote mount solution including:* Increased storage for batteries and/or hydrogen between frame rails* Approximately 363 kg weight savings* Smaller packaging envelope* High modularity for wide application coverage* Increased range and/or payload* Greater overall efficiencyWe project to eliminating 4.2 million tonnes of CO2 per year by 2025\. The high efficiency, and reduced weight and space of the powertrain will improve range and/or payload and therefore potentially improving CO2 reduction in a highly criticised sector. The extensive benefits of this new powertrain will equally provide accelerated adoption of battery-electric, fuel cell, and range-extended hybrid commercial vehicles.To deliver the project, Meritor will create a Centre of Excellence in Cwmbran with expanded testing facilities and R&D team. Danfoss will develop and assemble motors with integrated inverters at a Low- Carbon Innovation Centre near Edinburgh. Electra will assemble vehicles with plans to complete durability and field running at U.K. test tracks and on public roads. The vehicles will also be used to demonstrate the technology to major global vehicle manufacturers, fleets, and other potential end users.The total U.K. project expenditure of £82m is projected to create 189 jobs in the U.K. while safeguarding approximately 500\.
