The transportation sector accounts for 18-22% of Canadas GHG emissions. Global commitment to reducing emissions means massive growth potential for electric vehicle (EV) technology. One key hurdle limiting EV uptake is the limited real-world performance of EV lithium batteries, dictating range and longevity. The research comprises: 1) utilizing an innovative in-situ impedance measurement of battery cells within the Battery Management System (BMS), enabling accurate state-of-charge, state-of-health, temperature and real-time power-limit calculations during driving; 2) fully leveraging Silicon Carbide fast-switching power transistors in on-board EV battery charging systems for massive size and weight reductions.

交通部门占加拿大温室气体排放量的 18-22%。全球对减排的承诺意味着电动汽车 (EV) 技术的巨大增长潜力。限制电动汽车普及的一个关键障碍是电动汽车锂电池在现实世界中的性能有限，决定了续航里程和寿命。该研究包括：1）在电池管理系统（BMS）中利用创新的原位电池阻抗测量，实现驾驶过程中准确的充电状态、健康状态、温度和实时功率限制计算； 2) 在车载电动汽车电池充电系统中充分利用碳化硅快速开关功率晶体管，以大幅减小尺寸和重量。
