Current worldwide government incentives to reduce greenhouse gas emissions have spurred electric vehicle (EV) development, particularly for urban use. The number of such vehicles is expected to grow exponentially to 30 million by 2040. However, unless affordable, efficient and sufficient battery charging technologies are developed, EVs will not be adopted, deployed and utilized to full advantage. One of the major challenges in mass deployment of battery electric cars is the lack of charging stations in shopping areas and workplaces. At present, in most urban areas, the main option is to charge EV batteries using the on-board charger, which can take up to twenty hours to complete. Even fast charging stations require a half hour for recharging, and are few and sparsely situated. In either case, the conventional technology has low power conversion efficiency, requiring fans to manage heat dispersal which often break down, and are so bulky in design that they require cranes and other heavy duty equipment to install. The proposed NSERC Alliance Mission project promises to develop a novel battery charger architecture for EVs that will be attractive to consumers, not only in increasing speed of recharging and reducing the amount spent on electricity, but also in decreasing unnecessary energy losses and physically building compact charging stations to meet a global demand. The research will result in a highly efficient power architecture for ultra-fast charging stations that can charge EVs in about the time it takes to fill a conventional car with gas. Through prototype development for ultra-fast charging stations for energy storage batteries, this Project will help EVs become a mainstream transportation option.

当前全球政府减少温室气体排放的激励措施刺激了电动汽车（EV）开发，尤其是在城市使用方面。预计到2040年，此类车辆的数量预计将成倍增长到3000万。但是，除非开发出负担得起，高效和足够的电池充电技术，否则将不会采用，部署和利用EVS来充分利益。电池电动汽车大规模部署的主要挑战之一是购物区和工作场所缺乏充电站。目前，在大多数城市地区，主要选择是使用车载充电器为电动汽车电池充电，最多可能需要20个小时才能完成。即使是快速充电站也需要半小时才能充电，而且位置很少。无论哪种情况，传统技术都具有低功率转换效率，要求风扇管理经常分解的热量分散，并且设计笨重，以至于需要起重机和其他重型设备即可安装。拟议的NSERC联盟任务项目有望为电动汽车开发一种新颖的电池充电器体系结构，这将对消费者具有吸引力，这不仅是为了提高充电速度和减少用于电力的速度，而且还可以减少不必要的能源损失和物理建立紧凑的充电费用达到全球需求的电台。这项研究将导致高效的超快速充电站的功率架构，该站可能会在大约在传统汽车中用气体填充电动汽车的时间。通过用于储能电池的超快速充电站的原型开发，该项目将有助于电动汽车成为主流运输选项。
