The global use of passenger Electric Vehicles (EV) and Light Electric Vehicles has grown exponentially over the past decade. In 2018 alone, over 2 million passenger EVs were adopted, reinforcing this trend. The use of Light Electric Vehicles (LEV) covers important markets such as industrial vehicles, utility vehicles, and 2 to 4-wheel urban vehicles. LEVs have penetrated immensely with global sales over USD $9B in 2017 and expected to triple by 2026. In particular, electric scooters and electric bikes are becoming popular in high-density areas due to their affordable price, agility, and convenient parking. The objective of the collaboration between Dr. Ordonez at UBC and Delta-Q Technologies is to develop the next generation of high-efficiency, smart, and rapid battery chargers for electrified transportation systems and LEVs. Advances in this area will improve the power conversion efficiency, enhance the battery charging speed, and promote the adoption of sustainable transportation, benefitting utilities, consumers, and society. High-efficiency power conversion mitigates utilities' power quality issues; rapid battery chargers reduce consumers' range anxiety; sustainable transportation improves the quality of living. The research targets the development of novel LEV battery chargers using innovative power conversion technologies. The anticipated outcome is the reduction of power losses in the charger circuits by 40%. In turn, the charger's power density and battery charging speed will be improved substantially. This project will help the industry leader and B.C.-based Delta-Q maintain a competitive advantage over international competitors. The project will enable UBC to provide training to future engineers in power conversion. The trainees under the project will be exposed to a range of cutting-edge techniques and will be positioned to succeed in the field of renewable power conversion. The project is very timely since it anticipates the high demand for engineers in alternative energy.

过去十年，全球乘用电动汽车 (EV) 和轻型电动汽车的使用量呈指数级增长。仅 2018 年，电动乘用车的保有量就超过 200 万辆，进一步强化了这一趋势。轻型电动汽车（LEV）的使用涵盖工业车辆、多用途车辆、2至4轮城市车辆等重要市场。轻型电动车已广泛渗透，2017 年全球销售额超过 90 亿美元，预计到 2026 年将增加两倍。特别是，电动滑板车和电动自行车因其价格实惠、灵活且停车方便而在高密度地区越来越受欢迎。 UBC 的 Ordonez 博士与 Delta-Q Technologies 合作的目标是为电气化运输系统和 LEV 开发下一代高效、智能、快速的电池充电器。该领域的进步将提高电力转换效率，提高电池充电速度，并促进可持续交通的采用，使公用事业、消费者和社会受益。高效电力转换可缓解公用事业公司的电能质量问题；快速电池充电器减少了消费者的里程焦虑；可持续交通改善生活质量。该研究的目标是使用创新的电源转换技术开发新型 LEV 电池充电器。预期结果是充电器电路的功率损耗减少 40%。反过来，充电器的功率密度和电池充电速度也将得到大幅提升。该项目将帮助行业领导者和总部位于 BC 省的 Delta-Q 保持相对于国际竞争对手的竞争优势。 该项目将使 UBC 能够为未来的电源转换工程师提供培训。该项目的学员将接触到一系列尖端技术，并将在可再生能源转换领域取得成功。该项目非常及时，因为它预计了替代能源领域对工程师的高需求。
