Vehicle Electrical Systems Integration (VESI)

对电动汽车技术的迫切需求是显而易见的。因此，该项目涉及两个关键问题，即电力驱动系统的成本和功率密度，这两个问题都是将电动汽车推向大众市场的关键障碍。为了解决这些问题，需要进行大量的基础研究。在这里，我们分析并将问题划分为6个关键主题，并建议建立一些示范，以展示在基础科学和工程方面取得的进展。我们预计，在未来几十年，一种或多种不同形式的电动汽车将在欧洲和全球汽车市场，特别是轿车和货车市场实现大幅渗透。目前，阻碍电动汽车商业化的最大障碍是成本。在实现与内燃机（ICE）汽车的成本平价之前，电动汽车才会成为大多数消费者切实可行的选择。电动汽车的高成本通常归因于电池的成本，而实际上，电动动力系统的成本远高于内燃机汽车。我们有理由认为，电池技术将会得到巨大的改进，以应对这一巨大的市场机会，因此，电池技术将不再像目前某些地区所认为的那样，成为发展的瓶颈。我们相信，电动汽车上的电气系统集成将大大降低新兴电动汽车市场的成本。因此，我们的重点将放在电气传动系统的两个主要领域，即电动机和电力电子设备，这两个领域适用于所有类型的电动汽车。我们的驱动因素将是降低成本和提高功率密度，同时永远不会忽视大众市场的可制造性问题。

The urgent need for EV technology is clear. Consequently, this project is concerned with two key issues, namely the cost and power density of the electrical drive system, both of which are key barriers to bringing EVs to the mass market. To address these issues a great deal of underpinning basic research needs to be carried out. Here, we have analysed and divided the problem into 6 key themes and propose to build a number of demonstrators to showcase the advances made in the underlying science and engineering.We envisage that over the coming decades EVs in one or more variant forms will achieve substantial penetration into European and global automotive markets, particularly for cars and vans. The most significant barrier impeding the commercialisation EVs is currently the cost. Not until cost parity with internal combustion engine (ICE) vehicles is achieved will it become a seriously viable choice for most consumers. The high cost of EVs is often attributed to the cost of the battery, when in fact the cost of the electrical power train is much higher than that of the ICE vehicle. It is reasonable to assume that that battery technology will improve enormously in response to this massive market opportunity and as a result will cease to be the bottleneck to development as is currently perceived in some quarters. We believe that integration of the electrical systems on an EV will deliver substantial cost reductions to the fledgling EV market Our focus will therefore be on the two major areas of the electrical drive train that is generic to all types of EVs, the electrical motor and the power electronics. Our drivers will be to reduce cost and increase power density, whilst never losing sight of issues concerning manufacturability for a mass market.
