Novel solutions for battery thermal management and battery reuse

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样，致力于在不久的将来实现无排放运输。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，仍有大量工作要做。电池组需要保持在有利的温度范围内以获得最佳性能，电池热管理仍然是一个活跃的研究课题。除此之外，还需要开发电池再利用技术，以满足电动汽车行业的售后市场。首先，该项目将开发强大的电池热建模方法，以便开发高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，以预测在现实条件下的电池表面的温度。其次，该项目将开发一种方法来评估废旧电池组的单个模块，并根据其健康状况对其进行评级。这种方法可用于再制造替换电池组，作为为二手车辆购买新电池的具有成本效益的解决方案。最后，该项目将开发和展示一种以互联服务形式进行电池管理的新方法。这种方法旨在帮助扩散电池技术，以降低成本并激发创新。拟议研究活动的直接成果旨在协助两家加拿大公司扩大在加拿大的业务。拟议研究的其他成果将有助于加强加拿大在电池管理系统方面的领导地位和创新。

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.
