Battery-Enabled EV Fast -Charging Station

大规模电动汽车采用的突出障碍是“里程焦虑”，即，i）充电时间长，ii）相对较小 每次充电的距离覆盖范围iii）以及缺乏必要的或容易获得的充电基础设施， 特别是在农村地区。最常用的电动汽车充电器是1级和2级充电， 到8小时才能完全充满电动汽车的电池，不适合在长途旅行中使用。三级（快速） 充电时间为20-25分钟的充电器是电动汽车充电器发展的下一步， 长途/农村电动汽车旅行。这项由eCAMION和大学提出的产学合作计划 多伦多的公司将研究、开发、测试和安装电动汽车快速充电（3级）站原型，这些站利用 以网级锂离子电池为主要电源，为多个直流快速充电器供电。所设想的充电 在未来三年内，该站主要用于农村地区的安装，例如，沿着加拿大 高速公路和其他主要交通走廊，以解决电动汽车长途和/或农村的“里程焦虑” 出行与现有的电动汽车快速充电器相比，所提出的技术既不需要高容量 公用事业馈电也不会导致公用电网中的电能质量问题。这两个功能使安装 充电站的基础上的需求和市场要求，并消除了需要i）访问 高容量公用设施馈电线或ii）馈电线升级，这会增加过高成本。本发明的电池模块 充电站i）从电网逐渐充电和/或ii）从本地可再生资源充电，即，太阳能光伏组件， 从而进一步减少温室气体排放和运行成本。该计划侧重于： 1-i）电池驱动的控制、保护和电源/能量管理软件/硬件的研发 快速充电站和ii）使用Si基电力电子转换器模块的充电站基础设施 用于充电装置和电站电池运行，适用于项目第2 - 3年内的应用。2-研发中心 下一代快速充电站，基于i）开发的控制系统的增强版和ii） 基于SiC的电力电子转换器模块，适用于本项目第三年之后的应用。

The salient barrier to large-scale EV adoption is "range anxiety", i.e., i) long charging time, ii) relatively small range of distance coverage per charge iii) and lack of necessary or readily-accessible charging infrastructure, particularly in rural areas. The most common used EV chargers are levels-1 and level-2 charges which take up to 8 hours to fully charge the EV's batteries and are not suited for use during long-distance travel. Level-3 (fast) chargers that take 20-25 minutes for charging are the next step in the evolution of EV chargers and enable long-distance/rural EV travel. This collaborative industry-university proposal by eCAMION and the University of Toronto is to research, develop, test and install prototypes of EV fast-charging (level-3) stations that utilize grid-level Li-ion battery as the main source to supply multiple DC fast-chargers. The envisioned charging station, within the next three-years, is primarily intended for installation in rural area, e.g., along Tans-Canada Highway and other main transportation corridors, to address "range anxiety" for EV's long-range and/or rural travel. In contrast to the existing EV fast-chargers, the proposed technology neither requires high-capacity utility-feed nor results in power quality issues in the utility grid. These two features enable installation of the charging station based on demand and market requirements and eliminates the need for i) access to high-capacity utility feeder or ii) feeder up-grade which can impose excessive cost. The battery module of the charging station is charged i) gradually from the grid and/or ii) local renewable resources, i.e., solar-PV units, and thus further reduces GHG emission and cost of operation. This program focuses on: 1- RD&D of i) control, protection and Power/Energy management software/hardware of the battery-enabled fast charging station and ii) charging station infrastructure using Si-based power electronic converter modules for charging unit and station battery operation, for applications within 2nd-3rd year of the project. 2- RD&D of next-generation fast-charging station based on i) enhanced version of the developed control system and ii) SiC-based power electronic converter modules for applications beyond the 3rd-year of this project.
