Among the key features of the developed e-axle, the high torque density 6-phase synchronous motor is fed by an high efficiency inverter adopting the last generation of SiC power MOSFETs. A DC/DC converter between the battery and the inverter permits a regulated high voltage dc-link during traction, and provides embedded compatibility with fast charging stations having different voltage ratings up to 800V. The e-axle is completed by a single speed transmission gearbox, an innovative cooling system and an on-board charger. Dedicated algorithms are developed for the control of the motor and the DC/DC converter, to maximize the efficiency during traction exploiting a variable dc-link voltage. After an overview and description of each e-axle component, the paper also details the planned exploitation strategy of the developed technologies.","PeriodicalId":104806,"journal":{"name":"2020 AEIT International Conference of Electrical and Electronic Technologies for Automotive (AEIT AUTOMOTIVE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130888752","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 basic operation of the converter is described and the stresses on the major passive components (i.e. DC-link capacitors, differential-mode inductors, common-mode chokes) are calculated, highlighting the general performance trade-off of each modulation strategy. This analysis is applied to a rectifier for electric vehicle (EV) ultra-fast charging connected to the European low-voltage grid (i.e. 50 Hz, 400 V line-to-line), adopting a 650 V DC-link. The best candidates concerning different performance metrics are identified and the most suitable strategy for EV battery charging is selected.","PeriodicalId":104806,"journal":{"name":"2020 AEIT International Conference of Electrical and Electronic Technologies for Automotive (AEIT AUTOMOTIVE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132095248","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}

A suitable design and power flow management of these components can remarkably mitigate the battery stress due to heavy charge/discharge power peak requirements, particularly in an urban traffic context. The proposed refined models of batteries and SCs enable a more accurate reproduction of the system performances in a highly uneven route, taking into account various electrical and mechanical issues. The optimal rating of the energy storage components for a typical urban drive cycle can then be identified by further parametric analyses.","PeriodicalId":104806,"journal":{"name":"2020 AEIT International Conference of Electrical and Electronic Technologies for Automotive (AEIT AUTOMOTIVE)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132121365","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}

Prescribed by the fast-paced world of consumer electronics, end-user expectations have been shaped in regard to time-to-market, update frequency and availability. High flexibility and, specifically in the automotive context, strict fault tolerance are demanded by the underlying both on- and offboard data infrastructure in order to be able to quickly react to rapidly changing demands and requirements during the lifetime of automobiles. Recent trends indicate a shift towards flexible and isolated, thus fault tolerant, software components that can be transparently deployed over the air. Latest developments have further led to portable, efficient and sandboxed representations of executables like WebAssembly. Contrary to cloud-first strategies, streaming all relevant data to the cloud and analyzing it offboard is, due to oft-needed high sample frequency and thus vastly increased data traffic, not always feasible. We therefore explore and discuss the potential of an efficient, scalable and unified distributed onboard computing- and data-acquisition-platform based on WebAssembly across a wide variety of vehicular electronic control units.","PeriodicalId":104806,"journal":{"name":"2020 AEIT International Conference of Electrical and Electronic Technologies for Automotive (AEIT AUTOMOTIVE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129347109","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}
