QUICK CHANGE SODIUM-ION TRACTION BATTERY FOR COMMERCIAL VEHICLE APPLICATIONS

重型货车将货物运送到英国各地的企业和消费者手中。然而，这些车辆大多是柴油驱动的，这意味着它们是与道路相关的温室气体和氮氧化物排放的巨大贡献者。英国政府为自己设定了到2025年温室气体排放量减少15%的目标。仅中型重型货车（8 - 18吨）一项，在任何给定时间内，英国道路上大约有88,000辆1 - 15年的卡车。这意味着到2025年所有重型货车温室气体排放量减少15%是一项具有挑战性的任务。运营商们正在慢慢地开始采取措施，以帮助减少车辆排放，但由于成本高，加上缺乏实际测试，他们仍然持怀疑态度。特斯拉（Tesla）、尼古拉（Nikola）和康明斯（Cummins）已经展示了一些大型电池卡车的新技术，但即使是这些技术，要成为主流也需要几年的时间。需要在短期内有针对性地减少重型车辆的排放。目前，一个小型但成功的改造行业专注于小型货车和公共汽车的减少污染或节省燃料的技术。这项可行性研究的目的是通过帮助实施具有成本效益的电池解决方案，使复古改装市场更进一步，从而使电动动力系统不再仅仅是新车购买者采用的系统。目前，全电动动力系统50%以上的成本都花在牵引电池技术上。作为该项目的一部分，领先的研发机构AJE动力总成有限公司将与世界领先的非水钠离子电池技术Faradion英国有限公司一起进行可行性研究，研究采用钠离子电池技术的好处，并将其应用于世界上第一个用于中程HGV的钠离子牵引电池组。除了技术方面，该项目还将专注于可更换电池组系统，该系统将允许快速更换耗尽的电池组，并且与传统的锂离子牵引电池应用相比，钠离子电池技术具有环境效益。如果这项可行性研究被证明是成功的，那么该联盟的目标是在适当的时候向商用车行业公开介绍一种成本更低的钠离子牵引电池替代品。

Heavy goods vehicles transport goods to businesses and consumers throughout the UK. However the majority of these vehicles are diesel powered meaning they are a huge contributor of road related greenhouse gases and Nox emissions.The UK government has set themselves a target of a 15% reduction in HGV greenhouse gases by 2025\.For medium sized HGVs (8 - 18 ton) alone there are approximately 88,000, 1 - 15 year old trucks on UK roads at any given time.Meaning the 15% by 2025 GHG reduction for all HGVs is a challenging task.Operators are slowly beginning to adopt measures that help to improve a reduction in vehicle emissions, However they still remain sceptical due to high costs combined with a lack of real world testing.Tesla, Nikola and Cummins have show cased some of their new technologies for large battery trucks but even these are some number of years away from becoming main stream.HGV emission reduction needs to be targeted in the near term.Currently a small yet successful retrofit industry concentrates on pollution reducing or fuel saving technologies for small vans and buses.The purpose of this feasibility study is to take the retro fit market one step further by helping to implement a cost effective battery solution so as electric powertrains are then not only a system adopted by new vehicle purchasers.Currently over 50% of the cost for an all electric powertrain lies within the traction battery technology.AJE Powertrain Limited a leading research and development organisation along with Faradion UK Ltd a world leader in non-aqueous sodium-ion cell technology will as part of this project conduct a feasibility study looking at the benefits of taking sodium-ion cell technology and applying it to the worlds first sodium-ion traction battery pack for a medium range HGV.As well as the technological aspect the project will also focus on a swappable battery pack system that will allow for a quick change of the depleted battery packs and the environmental benefits of sodium-ion cell technology when compared to that of the more traditional lithium-ion traction battery application.Should this feasibility study prove to be successful then the aim of the consortia is in due course to publicly introduce a lower cost sodium-ion traction battery alternative to the commercial vehicle industry.
