A key enabler to wireless powertrain networking is the ability to exploit redundancies within multiple signals so as to reduce the required networking bandwidth. We provide an approach for bandwidth reduction which uses unsupervised learning in order to develop the training sets for long short term memory that reduces the number of signals transmitted.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123868386","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}

However, these appealing characteristics are heavily affected by the battery's operating temperature, which is the result of the ambient temperature augmented by the heat generated from the battery. To maintain the lithium-ion battery's operating temperature within the optimal range, an efficient battery thermal management system (TMS) is important and essential. Understanding the battery heat generation and battery temperature variation during its operations is required for designing the efficient battery TMS. In this paper, the temperature variations of a 20Ah lithium polymer battery cell during different driving cycles with different cooling media are studied. An electric vehicle model based on the 2018 Nissan Leaf is built in the GT-SUITE with experimental battery data. The temperature variation of the battery cell during different driving cycles is tested and simulated by using the terminal current generated by the GT-SUITE driving cycle simulations. Effects of air cooling and liquid cooling are also compared. With cooling air at 298K, the cell temperature increases between 2.3K to 5.1K to steady state from 298K, depending on the driving cycles. Cell temperature increase with cooling by liquid is only between 0.7K to 2.8K.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125908814","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}

For the tests, the modules were placed in a thermal chamber at 20°C and coolant was circulated through the modules with a chiller set to 20°C. Several characterization tests, including thermal resistance tests, fast charging tests up to 5C, and drive cycle tests were designed and performed on the battery module.

This study analyses two EV specific TOU rates in place from a customer and the grid perspectives. The analysis relies on a developed optimal cost model with coordinated charging strategies that minimizes the total cost of a workplace charging station over its lifetime. From a customer perspective, it is shown that the cost benefits are not always achievable and depends on the rates provided. From the grid perspective, the peak demand is found to be increased. Thus, the EV specific rates may not always provide an efficient use of the grid assets.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129077640","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}

Compressed deviation in the DC Link voltage is the additional asset of this method. As compared to the already reported methods, the proposed method gives a better peak CMV, DC Link voltage deviation and safe operating region.

This paper develops unified modeling frameworks for coupled traffic and power infrastructure, that capture the major cross-interactions between vehicular traffic flow and the power grid. The proposed models can then be used for long-time development of the power grid to facilitate possible traffic scenarios, energy trading, and short-time control to implement power grid response actions to traffic incidents.","PeriodicalId":339989,"journal":{"name":"2021 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129675643","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 aerospace industry has seen a focus on reducing weight, operating temperature, and pumping power of power converters, since these will limit an aircrafts' range and load carrying capacity. This paper outlines a tool which was created in MATLAB to automate the cold plate design process for DC-DC converters. The tool incorporates parametric sweeps for both staggered and aligned pin fin configurations to find the optimal design which maintains the devices below their critical junction temperature while reducing overall weight, and pumping power of the system. Using this design tool, an initial thermal design can be proposed with an acceptable trade-off of all critical parameters.
