The proposed solution enables high modularity in AC-DC power converters designated for EV charger systems, where the AFE modules can be separated and recombined, enabling them to be more versatile, flexible and scalable. The presented AFE rectifier system consists of several self-sufficient modules with distributed control that can exchange data through CAN bus. The proposed system has functions like dynamic resource allocation, automatic interleaving, circulating current control, accurate current sharing and demonstrates increased fault tolerance. In this paper, the main operating principle of the masterless control of modular AFE rectifier systems is explained. Moreover, the performance of the AFE rectifier system supplying power to a 100 kW off-board DC charger is demonstrated by MATLAB Simulink with changing load, module failures and possible manufacturing flaws.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133327692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Damaged or defective packs must currently be transported in explosion-proof steel containers to meet international regulations, which makes transportation expensive. Freezing has been identified as a potential means to avoid these significant costs since cryogenically frozen cells are safe and therefore subject to less stringent transportation legislation. Existing literature demonstrates that flash freezing has little effect on LIB electrical performance (energy capacity and impedance), during the whole automotive life of the cells (up to 20% capacity fade). However, it is impractical to flash freeze LIB packs due to their large thermal mass. Promisingly, this study suggests slower freezing rates (0.5 to 50°C/min) have no detrimental electrical performance effects, indicating whole LIB packs could be frozen without affecting performance. In an effort to minimise the energy requirements of freezing an entire LIB pack, this research also establishes that -35°C is the minimum temperature to prevent thermal runaway of Panasonic 18650 cylindrical cells during an external short circuit. This finding will help to guide the necessary in-transport temperature monitoring systems. Overall this work makes significant steps forward in optimising cryogenic strategies to facilitate reuse and remanufacture of LIB cells from a damaged pack. Development of this approach could prolong LIB useful life leading to reduced raw material consumption and improving environmental sustainability of EV adoption.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123029775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The project proposes a new circular economy strategy to contribute towards zero-emissions in a sustainable manner by retrofitting the existing fleet of ICE cars. Requirements for Ultra Low Emission vehicles will create a fleet of 15 million non-compliant ICE cars in the UK alone which is currently expected to be exported, recycled, or disposed of. Ecofitting may not only benefit the individual OEM, but the wider supply chain and ultimately the wider economy by developing an entire ecosystem around remanufacturing, redistribution, repair, reuse, refurbishment, and design.Ecofitting proposes an alternative strategy that not only involves the electrification of this fleet but, importantly, the customisation and personalisation of these vehicles to create desirability, promote behavioural change, and long-term ownership. As such, design is at the heart of this new strategy. The research identified trends in automotive design, lifestyle, and behaviour of the next generation of consumers that can support an alternative approach to automotive design. It concludes by proposing that Ecofitting design shall reflect values of sustainability in aesthetics.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123475666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, one of the most important topics tightly linked with this alternative refers to the greenhouse gas (GHG) emissions produced along the entire vehicle’s life cycle. The aim of the present work is to develop an emission-model that is able to calculate the CO2 emissions produced along the entire vehicle’s life cycle, so to estimate EV CO2 emission values and compare them with those of ICEV. The emission model, developed leveraging on a thorough literature review on the topic, is then applied to the Italian context, to enable a comparison of the emission results for EVs and ICEVs taking into account the peculiarities of such country. It emerges that overall CO2 emissions associated to EVs are lower than the ones associated to ICEVs. A significant portion of emissions arising from the manufacturing of the battery pack still represents the main gap to be filled with respect to ICEVs. Evaluating both vehicle typologies and based on different assumption in terms of the geographical locations in which the stages of the vehicle life cycle take place, it emerges that EVs show a consistent CO2 emission reduction ranging between -11% to -50% compared to ICEVs over the entire vehicle’s life cycle. The most relevant contribution for such performance is due to the cleaner energy mixes on which some countries can rely on compared to others. Given that the most impactful phase – in terms of CO2 emissions - is represented by the vehicle use, it has been performed a sensitivity analysis on the energy mix used for vehicle’s charging. Results show that coupling of Renewable Energy Sources (RES) and EVs can be a key factor for achieving very low emission values.","PeriodicalId":166751,"journal":{"name":"2020 Fifteenth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127316342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
