In this case, large amounts of used batteries will need to be treated. The total demand for electric storage devices is estimated to be 200 GWh by 2025. The duration of the process of degradation in nature of an electrical storage device is estimated to be around over 5000 years. Life cycle length is a very important parameter. Although the device as such does not pose a health hazard, it has disastrous consequences for the environment, environment in various forms (soil pollution, water pollution), due to the thousands of years in which the materials of their component naturally degrade (Cd, Ni, Li, Co, Mn, Al. Fe, Hg). The aim of this paper is to demonstrate the results of research on extending the life of Lithium-ion batteries in electric vehicles.

This research presents a sound engine capable of generating binaural sounds in real-time. Besides real-time binaural sounds, the engine can also enhance real-time spatialization, which results in an improved sound cue perception. The engine performance in providing sound cue feedback was tested through different trials, having visually impaired individuals as test subjects.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129619608","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}

Energy independence is obtained by using Dye-sensitized Solar Cells (DSSC) as the energy source and at the same time they act like infrared light filter decreasing water consumption by reduction of the rate of evapotranspiration. Also, in order to acquire the energy independence, they are used for geothermal heating/cooling system and solar tracking method to optimize solar energy absorption of DSSCs. To reduce the shaded area, the supporting structure of DSSCs is 3D printed using transparent materials. All data like temperature, humidity, amount of energy consumption/absorption are stored in cloud and analyzed to improve system efficiency.","PeriodicalId":426485,"journal":{"name":"2021 IEEE 27th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128838140","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 steady-state temperatures of the stator coils, stator core and the rotor were obtained to be 66.0 °C, 63.0 °C and 75.8 °C, respectively.
