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

交通运输部门占加拿大温室气体（GHG）排放总量的28%。随着2018年对碳排放实行国家定价，电动汽车（EV）将不可避免地在实现加拿大到2030年将温室气体排放量从2005年水平总体减少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电力电子专家Trescases教授、热管理专家Amon教授和加拿大Havelaar公司的合作，Havelaar是一家总部位于多伦多的创新型电动汽车制造商，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理事会合作。这项研究解决了限制电动汽车广泛普及的几个关键障碍，即当今保守设计的锂电池组的高成本和有限的实际性能，最终决定了电动汽车的行驶里程和寿命。本研究的目标是展示颠覆性的电池和车载充电系统，该系统结合了联合收割机：（1）在电池水平上的基于阻抗的实时荷电状态（SOC）、健康状态（SOH）和功率可用性确定，（2）高精度主动平衡，（3）电池组内的选择性和局部化液体加热/冷却，以及（4）优化的机械/电力电子设计，以实现向并网固定电池应用的无缝过渡。这项研究代表了为将EV电池过渡到固定的第二生命应用提供整体设计方法的首批举措之一。在这个所谓的“第二次生命”中，旧的和退化的电动汽车电池将被重新利用，以稳定交流电网，促进可再生能源的整合，同时进一步从电动汽车中获得价值。最终，这项研究将导致更实惠的电动汽车，在现实世界条件下具有更长的行驶里程，并减少碳足迹。Havelaar将利用这些研究成果，将其部署在即将推出的电动汽车平台上，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一流的培训和就业机会。

The transportation sector accounts for 28% of total Greenhouse Gas (GHG) emissions in Canada. With anational price on carbon to be imposed in 2018, Electric vehicles (EVs) will inevitably play an integral role inmeeting Canada's commitment to a 30% overall reduction in GHG emissions from 2005 levels by 2030. Thisfour-year multi-disciplinary research project is a collaboration between Prof. Trescases, a power electronicsexpert; Prof. Amon, a thermal management expert; and Havelaar Canada, a Toronto-based innovative EVmanufacturer that unveiled the world's first made-in-Canada electric pickup truck in May 2016. The team willalso 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 costand limited real-world performance of today's conservatively-designed lithium battery packs, which ultimatelydictate the EV driving range and longevity. The goal of this research is to demonstrate disruptive battery andon-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) selectiveand localized liquid heating/cooling within the pack, and (4) optimal mechanical/power-electronics design toenable a seamless transition to grid-tied stationary battery applications. This research represents one of the firstinitiatives to provide a holistic design approach for transitioning EV batteries to stationary second-lifeapplications. In this so-called "second-life", old and degraded EV batteries will be repurposed to stabilize theAC 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 conditionsand a reduced carbon footprint. Havelaar will exploit the research outcomes, deploying them in their upcomingEV platforms and increasing Canada's competitiveness in clean transportation, while providing world-classtraining and employment opportunities in the heart of Canada's innovation district.
