Electro-thermal Management and Charging of Next-Gen Automotive Batteries with Seamless Transition to**Second-Life Stationary Applications

运输部门占加拿大温室气体(GHG)排放总量的28%。随着2018年全国碳排放价格的实施，电动汽车(EVS)将不可避免地在履行加拿大到2030年将温室气体排放量在2005年水平上总体减少30%的承诺方面发挥不可或缺的作用。这个为期四年的多学科研究项目是由电力电子专家特雷斯凯斯教授、热管理专家阿蒙教授和多伦多创新电动汽车**制造商Havelaar Canada合作完成的，该公司于2016年5月推出了世界上第一辆加拿大制造的电动皮卡。该团队还将**与埃因霍温理工大学和加拿大国家研究委员会合作。**这项研究解决了限制电动汽车广泛普及的几个关键障碍，即高成本**和当今保守设计的锂电池组有限的现实世界性能，这最终决定了电动汽车的续航里程和寿命。这项研究的目标是展示破坏性电池和**板载充电系统，这些系统结合了：(1)基于阻抗的实时充电状态(SOC)、健康状态**(SOH)和电池级别的电源可用性确定，(2)高精度的有源平衡，(3)选择性**和电池组内的局部液体加热/冷却，以及(4)最佳机械/电力电子设计，以**实现向并网固定式电池应用的无缝过渡。这项研究是为将电动汽车电池过渡到静止的第二生命**应用提供整体设计方法的首批**倡议之一。在这种所谓的“第二人生”中，旧的和退化的电动汽车电池将被重新用于稳定交流电网和促进可再生能源整合，同时进一步从电动汽车中获得价值。**最终，这项研究将导致更负担得起的电动汽车，在现实世界条件下行驶更长的里程**并减少碳足迹。Havelaar将利用研究成果，将其部署在即将到来的**电动汽车平台上，并提高加拿大在清洁交通方面的竞争力，同时在加拿大创新区的中心提供世界级**培训和就业机会。

The transportation sector accounts for 28% of total Greenhouse Gas (GHG) emissions in Canada. With a**national price on carbon to be imposed in 2018, Electric vehicles (EVs) will inevitably play an integral role in**meeting Canada's commitment to a 30% overall reduction in GHG emissions from 2005 levels by 2030. This**four-year multi-disciplinary research project is a collaboration between Prof. Trescases, a power electronics**expert; Prof. Amon, a thermal management expert; and Havelaar Canada, a Toronto-based innovative EV**manufacturer that unveiled the world's first made-in-Canada electric pickup truck in May 2016. The team will**also collaborate with the Eindhoven University of Technology and the National Research Council of Canada.**This research addresses several key hurdles that limit the widespread penetration of EVs, namely the high cost**and limited real-world performance of today's conservatively-designed lithium battery packs, which ultimately**dictate the EV driving range and longevity. The goal of this research is to demonstrate disruptive battery and**on-board charging systems that combine: (1) real-time impedance-based state-of-charge (SOC), state-of-health**(SOH) and power availability determination at the cell level, (2) high-precision active balancing, (3) selective**and localized liquid heating/cooling within the pack, and (4) optimal mechanical/power-electronics design to**enable a seamless transition to grid-tied stationary battery applications. This research represents one of the first**initiatives to provide a holistic design approach for transitioning EV batteries to stationary second-life**applications. In this so-called "second-life", old and degraded EV batteries will be repurposed to stabilize the**AC power grid and facilitate renewable energy integration, while further deriving value from the EV.**Ultimately, this research will lead to more affordable EVs, with a longer driving range in real-world conditions**and a reduced carbon footprint. Havelaar will exploit the research outcomes, deploying them in their upcoming**EV platforms and increasing Canada's competitiveness in clean transportation, while providing world-class**training and employment opportunities in the heart of Canada's innovation district.
