EV-Join

汽车电气化是实现全球二氧化碳减排立法要求的关键。城市内的零排放、更高质量和更高性能的电动汽车(EVS)也使它们更具吸引力。2018年全球电动汽车销量为200万辆，其中68%为电池电动车(Bev)，31%为插电式混合动力汽车(PHEV)，年增长率为57%。通过技术进步和规模经济，预计到2030年，电池成本将从目前的155欧元/千瓦时降至90欧元/千瓦时。然而，目前有几个问题限制了进一步的开采。电动汽车的大批量生产在英国仍处于起步阶段，即使是领先的制造商也缺乏设计系统的知识，这些系统可以通过适合批量生产的工艺轻松制造。这些电动汽车系统是组装的，最终必须全部连接在一起(单个电池、模块、电池组到电机、复杂的PEMD系统)，每个电动汽车动力系统可能需要10,000-100,000个以上的焊接。然而，实现这些连接所需的加入过程涉及许多复杂的问题。电动汽车生产商，从中小企业到原始设备制造商(OEM)级，努力选择兼容的材料和连接工艺，指定和设计所需的电动汽车系统，并选择合适的制造工艺。EV-Join项目将提供一个用户友好的软件工具，解决开发EV系统的公司面临的主要问题，即：*允许创建可行的联合设计的选择过程，考虑到要连接的材料和所需的几何形状。*为材料组合和连接几何选择合适的连接工艺。*协助计算生产率和成本，以帮助用户选择生产工艺。*协助规划生产线工艺，同时考虑到每种连接组合和生产工艺的要求和限制。这将包括对关键的上游和下游工艺的要求。*在服务连接特性方面，实现这些特性的制造工艺要求。有了这一点，EV-Join将为整个制造业打开局面：*减少英国供应链中所有规模的制造企业的上市时间。*考虑到要连接的材料、生产率和几何要求，更有效地选择连接过程。*改进并保持焊接质量。*提高生产率，减少维修和报废。*减少并可能消除对昂贵和耗时的焊后无损测试(NDT)的需求。

Electrification of vehicles is key to achieve global legislative requirements for CO2 emissions reductions. Zero emissions within cities, higher quality and higher performance electrified vehicles (EVs) is also making them more attractive. \>2 million EVs were sold globally in 2018, 68% were battery electric vehicles (BEV) and 31% were plugin hybrid electric vehicles (PHEV), with an annual growth rate of 57%. Pack costs are expected to reduce from €155/kWh today to €90/kWh in 2030, through technological advancements and economies of scale. However, several issues currently limit further exploitation. High-volume EV production is still in its infancy in the UK and even the leading manufacturers lack the knowledge to design systems that can be readily manufactured by processes suitable for volume production.These EV systems are assembled, and must finally all be connected together (individual cells, to modules, to battery packs to motors, to complex PEMD systems), with potentially 10,000 -- 100,000+ welds per EV power train required. However, numerous complex issues are associated with the joining processes required to achieve these connections. EV producers, SME through to Original Equipment Manufacturer (OEM) level, struggle to select compatible materials and joining processes, to specify and design the required EV systems and to select suitable manufacturing processes._The EV-Join project will provide a user friendly software tool that addresses major issues faced by companies developing EV systems_, namely:* A selection process that allows feasible joint designs to be created, taking into account materials to be joined and required geometries.* A selection of suitable joining processes for the materials combinations and joint geometries.* Assistance with a calculation of production rates and costs to aid a user in selecting a production process.* Assistance for planning of production line processes taking into account the requirements and limitation of each joint combination and production process. This will include requirements for critical upstream and downstream processes.* In service joint properties, manufacturing process requirements to achieve those properties.With this, EV-Join will unlock, for manufacturing as a whole:* Reduced time-to-market for all sizes of manufacturing businesses in the UK supply chain.* More efficient selection of the joining process, taking into account materials to be joined, productivity and geometries requirements.* Improved - and maintained - weld quality.* Increased productivity and reduction in repairs and scrap.* Reduced and potentially eliminated need for expensive and time-consuming post-weld Non-Destructive-Testing (NDT).
