In Canada, transportation contributes over 23% of annual greenhouse gas (GHG) emissions. A key component of strategies to reduce GHG emissions in the transportation sector is the electrification of public transit via electric buses (e-Buses). The wide adoption of e-Buses necessitates advanced solutions for charging facilities that can handle high power, operate with high reliability, and have a small footprint. Moreover, to reduce stress on electrical infrastructure, a local energy storage system (ESS) will be important to shave the peak power demand of an e-Bus charging facility. This project addresses the above needs by designing and testing a high-power ESS-ready fast charger system for e-Buses. The project is a collaboration among a power electronics expert at the University of Alberta, a smart energy management expert at the University of Calgary, and industry partner eCAMION, a solution provider for the energy storage industry. The final outcome of the project will be a fully functional fast charger hardware and control prototype that will be an integral part of an e-Bus charging station. The project will provide vital knowledge and solutions to Canadian electric vehicles and e-Bus industries.

在加拿大，交通运输占年度温室气体排放量的23%以上。减少运输部门温室气体排放战略的一个关键组成部分是通过电动公交车实现公共交通的电气化。电动公交车的广泛采用需要先进的充电设施解决方案，这些解决方案可以处理高功率，高可靠性运行，并且占地面积小。此外，为了减轻电力基础设施的压力，本地储能系统（ESS）对于削减电动巴士充电设施的峰值电力需求至关重要。该项目通过设计和测试用于电动公交车的大功率ESS就绪快速充电器系统来解决上述需求。该项目是阿尔伯塔大学的电力电子专家、卡尔加里大学的智能能源管理专家和行业合作伙伴eCAMION（储能行业解决方案提供商）之间的合作。该项目的最终成果将是一个功能齐全的快速充电器硬件和控制原型，它将成为e-Bus充电站的一个组成部分。该项目将为加拿大电动汽车和电动巴士行业提供重要的知识和解决方案。
