This proposal is to acquire a battery test station/cycling apparatus to load cycle batteries and small battery packs targeted for the automotive hybrid power train application. Electrification of automotive systems has been increasingly concerned as the most promising future transportation solution to global energy crisis as well as more and more stringent requirements on environment protection through reduced emissions and resource conservation. The automotive industry is at the core of Ontario's economy with seven of the world's largest vehicle manufacturers operating 14 plants in the province. Development of leading-edge technologies related to electric vehicle systems would therefore considerably contribute to strengthening and enhancing the international competitiveness of Ontario automotive sector and also rapid growth of the Ontario's economy. The key sub-system of pure electric vehicles (EVs) and hybrid electric vehicles (HEVs) is the battery system. A pure electric vehicle uses batteries as its sole source of power while a hybrid electric vehicle (HEV) extends the range of a battery only electric vehicle by use of an engine or fuel cell. An EV is by its very nature a plug-in vehicle that can be charge from the electricity grid. Electric power storage systems are the bottleneck in the introduction of full electric vehicles to the market. The challenges in developing commercially viable electric power storage systems are many and this proposal is intended to use a multidisciplinary approach to address those that have hindered manufacturers from immediate production and marketing. Lithium-Ion (LiIon) technology was initially developed for consumer electronics applications (AA or AAA cells), and LiIon batteries for automotive applications require large prismatic cells which have fundamental differences in engineering design and operating characteristics that are not well understood at this time. Among the most important issues/challenges that this proposal is intended to address are the research programs to be supported with this equipment: 1) Batteries state of charge and life prediction and degradation modeling, 2) Thermal management of battery system, and 3) Batteries in-line monitoring and diagnosis.

本提案旨在获得一个电池测试站/循环装置，以加载循环电池和针对汽车混合动力系统应用的小型电池组。 汽车系统电气化作为解决全球能源危机的最有前途的未来交通解决方案，以及通过减少排放和节约资源来保护环境的要求越来越严格，越来越受到关注。汽车工业是安大略经济的核心，世界上最大的汽车制造商中有七家在该省经营14家工厂。因此，与电动汽车系统相关的前沿技术的发展将大大有助于加强和提高安大略汽车行业的国际竞争力，也有助于安大略经济的快速增长。纯电动汽车（EV）和混合动力汽车（HEV）的关键子系统是电池系统。 纯电动汽车使用电池作为其唯一的动力来源，而混合动力汽车（HEV）通过使用发动机或燃料电池来扩展仅使用电池的电动汽车的范围。 EV本质上是一种插电式车辆，可以从电网充电。 电力存储系统是将全电动汽车推向市场的瓶颈。开发商业上可行的电力存储系统的挑战很多，本提案旨在使用多学科方法来解决那些阻碍制造商立即生产和销售的问题。锂离子（LiIon）技术最初是为消费电子应用（AA或AAA电池）而开发的，而汽车应用的锂离子电池需要大型棱柱形电池，这些电池在工程设计和操作特性方面存在根本差异，目前还不清楚。本提案旨在解决的最重要的问题/挑战是该设备支持的研究计划：1）电池充电状态和寿命预测以及退化建模，2）电池系统的热管理，以及3）电池在线监测和诊断。
