与其他可充电电池技术相比，锂离子（Li-ion）电池具有能量密度高、重量轻、记忆效应可忽略、自放电率低等优点，被认为是最有前途的储能技术，已经在汽车、军事、消费电子等行业得到了广泛应用。尽管锂离子技术有许多优点和好处，但它还没有完全发展到满足工业中许多关键应用的性能需求和经济矩阵。电池管理系统的重大进步对于锂离子技术实现更广泛的市场渗透至关重要。因此，本课题的研究方向是开发先进的电池热管理系统（TMS）和健康管理系统（HMS），以实现更可靠、更高效、更紧凑、更轻重量和更长的循环寿命储能。在电池热管理方面，将开发一种更高效、更紧凑的基于微通道热管的TMS，以确保在高放电率下电池应用的最佳工作温度范围。所提出的电池TMS具有效率高、重量轻、封装紧凑等特点。在电池HMS方面，将开发一种全智能电池HMS，使锂离子电池组具有自我学习、自我诊断和自我预测三种新功能，以优化电池性能和提高可靠性。提出的电池热/健康管理系统将在Formula Hybrid和无人机的电池组上进行实验验证，在正常和滥用放电情况下，将确保电池组在所需的温度范围内运行，防止热失控，并提供实时电池性能优化、健康监测和故障预测。研究结果将允许能源存储行业将其资源更有效地用于开发更可靠、更紧凑、更高效的锂离子电池系统，这些电池系统将有助于保证在加拿大广泛的关键应用中相关设备或设备的高水平可靠性、可用性和生产力。此外，在储能、热管理、系统健康状态监测和寿命预测、信号处理和智能系统等方面培训HQP，将为加拿大各行业提供潜在的专家，这将促进加拿大经济和社会的进步。拟议中的电池TMS和HMS技术将拥有世界范围的客户，并将使加拿大的工业和大学处于创新的前沿，并帮助加拿大成为全球技术领导者和高附加值产品提供商。

Lithium ion (Li-ion) batteries are considered to be the most promising energy storage technology with higher energy density, lighter weight, negligible memory effect, and lower self-discharge rate when compared to other rechargeable battery technologies, and have already found many applications in industries such as automotive, military, and consumer electronics. Although offering many advantages and benefits, Li-ion technologies have not yet been fully developed to meet the performance needs and economic matrix for many critical applications in industries. Significant advancements in battery management systems are critically needed for the Li-ion technologies to achieve much broader market penetration. Accordingly, the proposed research is to develop advanced battery thermal management system (TMS) and health management system (HMS) for more reliable, more efficient, more compact, lighter weight and longer cycle-life energy storage. In battery thermal management, a more efficient and compact micro-channel heat pipe based TMS will be developed to ensure an optimum operational temperature range for battery applications under high discharge rates. The proposed battery TMS possesses the features of high efficiency, low weight, and compact package. In battery HMS, a fully intelligent battery HMS will be developed such that Li-ion battery packs can perform three novel functions, i.e., self-learning, self-diagnostics, and self-prognostics, for battery performance optimization and reliability enhancement. The proposed battery thermal/health management systems will be experimentally validated on the battery packs for a Formula Hybrid and an UAV under both normal and abusive discharge scenarios, and will assure the battery packs operate within a desired temperature range, prevent thermal runaway, and also provide real-time battery performance optimization, health monitoring, and failure prognostics. The findings of the research will permit energy storage industry to target its resources with greater effectiveness in developing more reliable, more compact, and more efficient Li-ion battery systems, and these battery systems would help guarantee the high-level reliability, availability, and productivity of the relevant devices or equipment in a wide array of critical applications in Canada. In addition, training HQP in energy storage, thermal management, system health condition monitoring and life prediction, signal processing, and intelligent systems, will provide Canadian industries with potential experts, which will promote the advance of economy and society in Canada. The proposed battery TMS and HMS technologies will have a world-wide clientele and will put Canadian industries and universities in forefront of innovation, and help Canada emerge as a global technology leader and high-value-added products provider in energy storage.
