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.

交通运输部门占加拿大温室气体（GHG）排放总量的28%。随着2018年全国碳价格的实施，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教授和多伦多创新电动汽车制造商Havelaar Canada之间的合作，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 ** 和有限的现实世界性能，这最终 ** 决定了电动汽车的行驶里程和寿命。本研究的目标是演示破坏性电池和 ** 车载充电系统，该系统结合了联合收割机：（1）电池级的实时基于阻抗的荷电状态（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 ** 和局部液体加热/冷却，以及（4）最佳的机械/电力电子设计，以 ** 实现向并网固定电池应用的无缝过渡。这项研究代表了第一个 ** 倡议，提供了一个整体的设计方法，将电动汽车电池过渡到固定的第二生命 ** 应用。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，这项研究将带来更实惠的电动汽车，在现实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。
