Novel solutions for battery thermal management and battery reuse

交通电气化具有减少环境污染的潜力。加拿大与大多数主要国家一道，承诺在不久的将来实现无排放交通。电池组是交通运输电气化的关键部件之一，为了提高电动汽车电池组的安全性、效率和可靠性，还有很多工作要做。为了获得最佳性能，需要将电池组保持在一个合适的温度范围内，电池热管理一直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来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，以预测现实条件下电池表面的温度。第二，该项目将开发一种评估废旧电池组各个模块的方法，根据其健康状况对其进行评级。这种方法可以用于重新制造替换电池组，作为为二手车购买新电池的经济有效的解决方案。最后，本项目将以互联服务的形式开发和演示一种新的电池管理方法。这种方法旨在帮助电池技术的扩散，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其在加拿大的业务。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.
