Ultra-Fast Chargers for Electric Vehicles

当前世界各国政府减少温室气体排放的激励措施刺激了电动汽车(EV)的发展，特别是在城市使用。预计到2040年，这类车辆的数量将呈指数级增长至3000万辆。然而，除非开发出负担得起、高效和足够的电池充电技术，否则电动汽车将不会被采用、部署和充分利用。大规模部署电池电动汽车的一大挑战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，这可能需要长达20个小时才能完成。即使是快速充电站也需要半个小时才能充电，而且数量很少，位置稀少。在任何一种情况下，传统技术的电力转换效率都很低，需要风扇管理散热，这些散热经常发生故障，而且设计太过笨重，需要起重机和其他重型设备来安装。拟议的NSERC联盟使命项目承诺为电动汽车开发一种新的电池充电器架构，该架构将吸引消费者，不仅在提高充电速度和减少电力支出方面，而且在减少不必要的能源损失和实际建造紧凑型充电站以满足全球需求方面。这项研究将为超高速充电站带来一种高效的电力架构，可以在大约传统汽车加满汽油的时间内为电动汽车充电。通过开发储能电池超快充电站的原型，该项目将帮助电动汽车成为主流交通选择。

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.
