SUMMARY:Licentiate defense – Yuki Kobayashi
DESCRIPTION:Title: Characterising electric vehicle usage patterns for smarter charging \nOn 4 June Yuki Kobayashi (Chalmers University of Technology) will present his licentiate thesis on how real-world electric vehicle (EV) usage can support smarter charging and more efficient energy systems. \nThe defense i taking place at Chalmers and online: https://www.chalmers.se/en/current/calendar/Yuki-Kobayashi-552119/ \nElectrification of passenger vehicles is an important measure to decarbonize the transport sector. An efficient introduction of electric vehicles (EVs) requires an understanding of how the charging of EVs impacts the electricity system and if\, and to what extent\, smart charging strategies\, including vehicle to grid (V2G) services\, can support the electric grid in the future energy systems. The aim of this thesis is to characterize the flexibility of smart charging including V2G by analyzing the real‑world driving\, parking\, and charging patterns obtained from logged EVs. The analysis is based on data collected from 394 privately owned EVs and survey responses from their owners. The results reveal substantial flexibility potential for smart charging from several perspectives. However\, the findings also highlight important limitations that must be carefully considered when estimating flexibility or implementing flexible charging into energy system models. \nUsing the lower state of charge (SOC) threshold for charging decisions and the SOC when charging ends\, the flexible battery capacity range is calculated to be 59% on average. The aggregated SOC for all logged EVs is within 60%–80% throughout the entire logging period. The results show that charging is needed in fewer than half of the days in a week for more than 73% of weeks\, regardless of the attributes of the EV owners\, including commuter category and battery capacity. Furthermore\, EVs are charged more frequently than the minimum number of charging events required per week. Thus\, there is potential for charging in a way that is flexible in time depending on\, for example\, grid congestion or spot prices. This is particularly the case for non‑commuters with large‑battery EVs. The amount of time that EVs are plugged in for smart charging differs by more than a factor of two if one assumes that EVs are plugged in whenever they are parked at home and that EVs are plugged in only when they charge during the parking event. Thus\, careful consideration of which of these assumptions is appropriate is essential when estimating the availability of EVs for smart charging\, as the choice can significantly affect the outcomes. Installation of chargers at workplaces can increase the number of grid-connected EVs at places other than the home location\, although very few EVs need to charge at workplace to fulfill their driving demand. Incentives to promote plug‑in behavior at the home location can\, therefore\, be prove to be cost-effective at increasing the number of grid-connected EVs. This flexibility at home is exploited by EV owners with hourly electricity contracts through selecting charging times when the spot price is lower than the daily average. In this thesis\, the logged EVs are clustered into three\, five\, and eleven clusters\, resulting in groups with distinct characteristics. When the number of clusters is increased from three to five\, a cluster with a low probability of parking at home during the night and a cluster maintaining a high SOC are added to the three clusters. When the number of clusters is extended to eleven\, some clusters exhibit combinations of characteristics that are not present in the case with five clusters\, including clusters with extreme values. Clusters with characteristics that diverge from typical commuter or non-commuter patterns are obtained.

SUMMARY:SEC Doctoral Student Network Summer School on Components and Systems for Electromobility
DESCRIPTION:Swedish Electromobility Centre and the SEC Doctoral Student Network are pleased to invite doctoral students and SEC’s industrial partners to this year’s Summer School\, focusing on Components and System Studies for Electromobility\, with particular emphasis on battery electric and fuel cell electric vehicles. This year\, the Summer School will be held at Hedenlunda Slott in Flen\, a peaceful and inspiring venue whose historic charm and beautiful natural surroundings provide an ideal setting for reflection\, learning\, and collaboration. \n  \nFormat\nThe Ph.D. course is intended for Ph.D. students within the SEC doctoral student network and employees of the SEC industrial partners in the field of e-mobility. The Summer School consists of lectures and practical exercises on the five themes in SEC\, as well as a home assignment. \n\nIntelligent Vehicle and Systems\nElectric Drives and Charging\nEnergy storage\nEnvironment and Society\nVehicle–Grid Interaction\n\nThe lectures will be led by theme leaders and their colleagues\, and several networking opportunities will take place during the course. \nThe school starts at 12:00 on 22 June\, and lectures begin at 13:15. We would like everyone to attend the welcome lunch\, but if you’re traveling a long distance and can’t arrive until 13:15\, please let us know by emailing us at phd@emobilitycentre.se. \nAfter the Summer School\, we will meet again so you can present your home assignment. Information about the date and location will be provided soon. \n  \nPractical information\nExamination and Credits: Assessment is based on attendance and completion of the home assignment. To pass the course\, participants are required to complete the assignment and deliver a final project presentation. The proposed number of credits is 5 hp. \nNB! To apply for these credits within your Ph.D. course curriculum\, you need approval from your examiner. \n  \nWhen and where?\nThe Summer School will run between 12:00 on 22 June and 15:00 on 26 June 2024\, and we are looking forward to meeting you at: \nHedenlunda Slott\, Hedenlunda\, 642 94 Flen \nHedenlunda Slott is located in the scenic countryside of Sörmland\, just outside Flen. Surrounded by lush greenery and tranquil landscapes\, the castle offers a peaceful and inspiring setting ideal for reflection\, learning\, and collaboration. More information about the venue and accommodation can be found here: https://www.hedenlundaslott.se/ \n  \nCourse material\nMost of the materials you need will be provided during the week. Some exercises will involve using MATLAB. If you have access to the program\, ensure it is installed on your computer. If not\, you can work with someone who has it installed. \n  \nCost\nThe Summer School fee is SEK 9\,000 (excluding VAT) per person for Ph.D. students from academia and SEC industry partners. Employees from SEC industry partners may attend\, subject to availability\, at a cost of SEK 10\,000 (excluding VAT) per person. SEC will send the invoice after the course week. Please have your billing details ready when you register. \nThe cost will cover: \n\nAccommodation in single rooms for four nights (Monday-Friday) at Hedenlunda Slott\nAll meals included (breakfast\, fika\, lunch\, and dinner)\nParticipation fee for the course\nRegistration and billing\n\n  \nCancellation policy \nCancellation before 19 May at no charge.\nCancellation after 19 May\, you will be charged 100% of the fee. \n  \nTravel \nYou need to arrange and pay for your own travel to and from the course location. Directions for Hedenlunda Slott will be sent to those who register. \n  \nQuestions?\nFor SEC- and administration-related questions\, please email phd@emobilitycentre.se. \nCourse content-related questions are best answered by the different theme leaders: https://emobilitycentre.se/research/ \n  \nRegistration\nPlease click HERE to register for the Summer School. \nRegister by 20 May at 17:00.
