The project consists of two subsystems. The first one, sensor measurements node, works as a temperature and humidity controller that can be programmed with a keypad. The measured data will be shown on the integrated display; an external control can also be performed using several optocoupled relays. The second subsystem collects the information sent by each node separately, merges and sends it to the online database for further remote processing. The 433 MHz radio communication technologies are used to transmit data from sensor nodes to the hub, Wireless technology is used to transmit information from the hub to the online database and 315MHz radio communication is used to transmit commands from the hub to sensor node individually. Atmel ATmega328 microcontroller is used for the node and Espressif ESP32 is used for the hub. This configuration represents an optimal solution in terms of cost and energy consumption for controlling and collecting data to the server. The Altium Designer application was used to design the PCB and its electrical and thermal parameters are simulated using the Ansys application suite.","PeriodicalId":413385,"journal":{"name":"2022 45th International Spring Seminar on Electronics Technology (ISSE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121942388","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 novelty of the article consists in evaluating the software delivery results according to the settings of the parameter simulation: time steps, integrations methods, losses due to deviation from standard solar spectrum, diffuse irradiation models, irradiation models on the inclined plane and others. The analytical investigations are carried out with the help of two EU certified software (PV-SOL and PV-GIS) dedicated to the solar forecast [1]. The experimental investigations, used for validation, are carried out at two different sites (West- and East-EU) on similar on-grid power conversion circuits. In detail, the behavior of both solar energy production systems is analyzed, by counting the amounts of generated energy over various sampling periods (day, month, year). Based on the mentioned comparison, conclusions regarding the parameter sensitivity and improvement of the estimated energy are drawn.","PeriodicalId":413385,"journal":{"name":"2022 45th International Spring Seminar on Electronics Technology (ISSE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129163620","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 advancement in these areas is closely related to the progress of battery technology. Although ongoing research into new battery chemistries shows promising results, Li-Ion batteries are still considered to be the state of the art, mainly because of their superior specific energy. Due to the high reactivity of lithium, the deployment of battery management systems (BMS) is crucial to ensure the safe and optimal use of Li-Ion cells. A precise state of charge (SOC) estimation is key for such applications. This paper proposes an adaptive solution for state of charge estimation, using a feedforward artificial neural network and machine learning. The training data consists of series of charge and discharge cycles for a Panasonic 18650PF Li-Ion battery, recorded at temperatures between $- 20 ^{circ}text{C}$ and $25 ^{circ}text{C}$. The model’s accuracy is validated using a variety of test datasets over a wide range of ambient temperature. The mean absolute error (MAE) obtained is between 1 % and 2 %, depending on the ambient temperature.","PeriodicalId":413385,"journal":{"name":"2022 45th International Spring Seminar on Electronics Technology (ISSE)","volume":"44 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125686750","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 development of a “green” solar module is of high relevance. For the series interconnection of solar cells, currently lead-containing solder alloys are used. The aim of this work is to evaluate the microstructure and impact on solar module performance of two industrially feasible interconnection materials with high potential for the interconnection of high-efficiency silicon heterojunction solar cells: lead-free solder and lead-free electrically conductive adhesives. Isothermal aging shows that the microstructure of soldered joints is submitted to significant changes such as intermetallic compounds growth (Ag3 Sn, Cu3 Sn, Cu6 Sn5) and, compared to glued joints, seem to influence the electrical performances of PV modules. The long-term stability is analyzed by thermal cycling of small-scale PV modules. Modular integration has been shown to be possible for both alternatives, about 80 % of the modules tested have successfully passed the thermal cycling test (power loss less than 5%).","PeriodicalId":413385,"journal":{"name":"2022 45th International Spring Seminar on Electronics Technology (ISSE)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128732203","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}

Nowadays, smart textiles designed for medicine or sports have been developed to be worn directly on the body, just like conventional textiles. This is the reason, why e-textiles and smart textiles should be able to withstand mechanical and chemical stresses during washing cycles. It is therefore essential to focus on their durability through repeated wash cycles. This paper focuses on the effect of washing cycles on the conductive fibers used in E-textiles. Two commercial conductive threads (Madeira HC12, SilverTech + 100) and two hybrid threads (T1, T2) were developed at the Faculty of electrical engineering at the University of West Bohemia and were selected for the experiment. The threads T1 and T2 consist of silver-plated copper microwires plied with PES multifilament threads. The commercial threads are based on silver-plated polyamide filaments. These filaments have an order of magnitude lower resistance than hybrid filaments. This paper investigates the change in electrical resistance of the four above-mentioned embroidered conductive threads due to their exposure to 30 washing cycles. The results of this experiment are presented in the paper, which shows that the coated commercial threads show better results after 30 wash cycles but are not suitable for all applications compared to the hybrid threads because of their higher electrical resistance. The wash resistance of hybrid threads can be increased by isolating individual microwires, which is not possible with plated yarns.","PeriodicalId":413385,"journal":{"name":"2022 45th International Spring Seminar on Electronics Technology (ISSE)","volume":"349 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122173159","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}
