项目摘要

E-bikes represent one of the best balances of personal utility and environmental performance of all forms ofurban road transport. This research will help promote the adoption of e-bikes and quantify how e-bikes can bemost appropriately used and to reduce emissions in Canada's urban centres can benefit, and will better positionExro to capitalize on the growing e-bike market using its advanced electric motor.Exro's electric motor is based on a new and patented control technology that shows great potential in achievinghigher efficiency over a wide range of operating speeds. The electric motor uses Dynamic PowerMangementTM (DPM) technology that senses changes in motor load and switches on the fly between eitherparallel or series arrangements of the multiple windings within the motor to achieve optimal efficiency over awide range. This project will adapt and implement this technology in e-bikes and assess its performance in avariety of driving cycles representative of actual use in various urban environments including personalcommuting and drayage. E-bikes require fairly significant variations in both speed and torque from theirelectric drive-train and Exro's DPM technology offers the potential of significant performance gains. Theproposed study will allow systematic assessment of the technology and identify critical developments requiredfor its commercial adoption in e-bikes.

电动自行车代表了所有形式的城市道路交通中个人效用和环境绩效的最佳平衡之一。这项研究将有助于促进电动自行车的采用，并量化如何最适当地使用电动自行车，减少加拿大城市中心的排放量，并将更好地定位Exro，利用其先进的电动机来利用不断增长的电动自行车市场。Exro的电动机基于一种新的专利控制技术，在广泛的运行速度范围内显示出更高的效率。电动机采用动态功率管理TM（Dynamic PowerManagementTM）技术，可感知电机负载的变化，并在电机内多个绕组的并联或串联布置之间动态切换，以在很宽的范围内实现最佳效率。该项目将在电动自行车中采用和实施这项技术，并评估其在各种驾驶循环中的性能，这些驾驶循环代表了在各种城市环境中的实际使用，包括个人通勤和拖运。电动自行车需要相当大的变化，在速度和扭矩从他们的电力传动系统和Exro的自行车技术提供了显着的性能增益的潜力。拟议的研究将允许系统评估该技术，并确定其在电动自行车中的商业应用所需的关键发展。
