Transport electrification has the potential to reduce environmental pollution. Canada, along with most major countries, has committed to achieving emission-free transportation in the near future. Battery packs are one of the crucial parts of transport electrification and significant work remains to be done in order to improve the safety, efficiency, and reliability of electric vehicle battery packs. Battery packs need to be maintained at a favorable temperature range for optimal performance and battery thermal management remains an active research topic. In addition to this, battery reuse technologies need to be developed to satisfy the aftermarket in the electric vehicle industry. First, this project will develop robust approaches to battery thermal modeling such that efficient battery thermal management solutions can be developed. Particularly, equivalent circuit modeling approaches will be combined with thermal propagation modeling in order to predict the temperature at the surface of the battery under realistic conditions. Second, this project will develop an approach to assess individual modules of a used battery pack to rate them based on their state of health. This approach can be utilized to remanufacture replacement battery packs as a cost-effective solution to buying new batteries for used vehicles. Finally, this project will develop and demonstrate a new approach to battery management in the form of connected service. This approach aims to help to proliferate battery technology in order to drive down costs and to stir innovation. Direct outcomes of the proposed research activities are designed to assist two Canadian companies to expand their operation in Canada. Additional outcomes of the proposed research will help to enhance Canadian leadership and innovation in battery management systems.

运输电气化有可能减少环境污染。加拿大与大多数主要国家一起致力于在不久的将来实现无排放的运输。电池组是运输电气化的关键部分之一，为了提高电动汽车电池组的安全性，效率和可靠性，还要做重大工作。电池组需要保持在有利的温度范围内，以实现最佳性能，并且电池热管理仍然是一个主动的研究主题。除此之外，还需要开发电池重用技术以满足电动汽车行业的售后市场。首先，该项目将开发出强大的电池热建模方法，以便可以开发出有效的电池热管理解决方案。特别是，等效电路建模方法将与热传播建模相结合，以预测电池表面在现实条件下的温度。其次，该项目将开发一种评估二手电池组的单个模块的方法，以根据其健康状况对其进行评分。该方法可用于再制造更换电池组，以作为购买二手车的新电池的经济高效解决方案。最后，该项目将以连接服务的形式开发并展示一种新的电池管理方法。这种方法旨在帮助扩散电池技术，以降低成本并搅动创新。拟议的研究活动的直接结果旨在帮助两家加拿大公司扩大其在加拿大的运营。拟议的研究的其他结果将有助于增强电池管理系统中的加拿大领导力和创新。
