Increasing Adoption of Electric and Electric Hybrid Vehicles through Consumer Relevant Powertrain Improvements and Characterization

混合动力汽车（hev）、插电式混合动力汽车（phev）以及电池或纯电动汽车（bev）的电动化程度不断提高，有许多积极的原因。不幸的是，出于务实、政策和行为方面的原因，电动汽车的销量普遍较低至中等。在所有电动汽车的优点和缺点的中心是汽车电池。许多电池研究已经存在并且仍在继续，但主要是在电池和实验室层面。在模块（多个单元）和包（多个模块）级别上的研究要少得多，而且由于商业竞争的原因，许多已经存在的研究往往在行业内保密。文献中一个明显不足的领域是关于汽车电池组的内部温度和寿命退化行为，以及它对电动汽车基于模型的设计的影响。第二个文献不足是有效的方法来说服汽车消费者对电动汽车的好处。

There are many positive reasons for the ever increasing electrification of vehicles in the form of hybrid electric vehicles (HEVs), plug-in HEVs (PHEVs), and battery or pure electric vehicles (BEVs). Unfortunately, for pragmatic, policy, and behavioural reasons electrified vehicles sales are generally low to moderate. At the centre of all electrified vehicle benefits and drawbacks is the vehicle battery. Much battery research exists and continues but mostly at the cell and lab level. At the module (multiple cells) and pack (multiple modules) level the research is far less, and much of what does exists tends to remain confidential within industry for business competition reasons. One clearly deficient area in the literature is with regards to vehicle battery pack' internal temperature and lifetime degradation behaviour, and its impact on electrified vehicle model-based design. A second literature deficiency is effective approaches to convincing the vehicle consumer on the benefits of electrified vehicles. The overall objective of this research program is to advance, both technically and consumer desirability wise, hybrid electric vehicle's (HEVs), plug-in hybrid electric vehicle's (PHEVs), pure electric or battery electric vehicle's (BEVs) powertrains in order to move society closer to a sustainable transportation future. Specifically, this research program focusses (i) on understanding and improving vehicle battery life and utilization through understanding vehicle battery thermal characteristics and degradation, and (ii) on developing a method to increase public support for increasing the electrification of vehicles through the development of a mobile toxic emissions multi-pathway human health risk assessment framework. There are three research program main challenges proposed for Discovery Grant funding: The first challenge fills a void in the literature and research tools as it seeks to extend the applicant's recently productive physics-based 3-D multi-layered battery pouch thermal modelling to include degradation, and up-sized to vehicle battery modules and packs. The second challenge addresses post battery warranty needs of the consumer and supports the emerging vehicle battery second-use industry by better understanding vehicle battery degradation through experiments and transferring this understanding to PHEV control optimization strategies geared towards extending battery life, and correspondingly second-use value. The third challenge will assist vehicle purchasing consumers, city traffic planners, and government decision makers by creating a novel, paradigm shifting, mobile toxic emissions human health risk assessment that seeks to inform, by personalizing, vehicle emissions down to the vehicle one drives, the driving routes one takes, and where one lives and works.
