Rapid battery charging technologies for light electric vehicles

乘用型电动汽车(EV)和轻型电动汽车(Light Electric Vehicles)的全球使用量在过去十年中呈指数级增长。仅2018年就有200多万辆乘用型电动汽车被采用，强化了这一趋势。轻型电动汽车(LEV)的使用覆盖了重要的市场，如工业车、多功能车和2至4轮城市车辆。Levs在2017年的全球销售额超过90亿美元，并预计到2026年将翻两番。特别是，电动滑板车和电动自行车因其价格实惠、灵活性和停车方便而在高密度地区变得流行起来。UBC的奥多尼兹博士和Delta-Q Technologies的合作目标是为电动交通系统和Levs开发下一代高效、智能和快速的电池充电器。这方面的进展将提高电力转换效率，提高电池充电速度，并促进采用可持续交通，造福公用事业、消费者和社会。高效的电力转换缓解了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续航焦虑；可持续交通提高了生活质量。这项研究的目标是利用创新的电力转换技术开发新型LEV电池充电器。预期的结果是将充电器电路中的功率损耗降低40%。反过来，充电器的功率密度和电池充电速度将得到大幅提高。该项目将帮助行业领导者和总部位于不列颠哥伦比亚省的Delta-Q保持相对于国际竞争对手的竞争优势。该项目将使UBC能够为未来的工程师提供电力转换方面的培训。该项目下的受训人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，因为它预计到替代能源领域对工程师的高需求。

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.
