Elektrikli araçlar kablolu şarj, batarya değiştirme ve kablosuz şarj yöntemleriyle şarj edilmektedirler. İletken şarj, kablo hasarlarına ve olumsuz hava koşullarına karşı dayanıksızdır. Batarya değiştirmede temel sorunlar maliyet ve batarya birikimidir. Kablosuz şarj ise kablo karmaşasını ortadan kaldırırken, sürücülere güvenli ve otonom bir şarj imkânı sağlamaktadır. Buna karşın kablosuz şarj verimi henüz istenen seviyede değildir. Bu çalışmada kablosuz güç transferi veriminin arttırılması amaçlanmış ve güç transferinin gerçekleştiği kompanzasyon sistemine yoğunlaşılmıştır. Dairesel ve çift-D geometrilerine sahip bobinler tasarlanarak farklı görev döngülerinde ve hava aralıklarında testler yapılmıştır. Kompanzasyon sistemine nüve ve kalkan eklenerek verim incelenmiştir. Daha sonra projeye özgünlüğünü veren malzeme-sensör sistemi kompanzasyon sistemine dahil edilmiştir. Dört farklı malzeme ve iki basınç sensörü kullanılarak transfer verimi üzerine etkiler araştırılmıştır. Deneyler sonucunda maksimum verim dairesel bobinler arasına yerleştirilen köpük malzemesiyle 55 mm hava aralığında %82.38 olarak elde edilmiştir. Nihai testler lityum iyon batarya paketiyle gerçekleştirilmiştir. Bataryalar 0.2, 0.5 ve 1.0C oranlarında şarj edilmiştir. Bu C oranlarında ortalama verim sırasıyla %82.89, 76.25 ve 61.93 olarak kaydedilmiştir. MATLAB ve Ansys programlarında benzetim çalışmaları yapılmış ve geliştirilen modeller doğrulanmıştır.

Investigation of Effects of Various Materials and Sensors on Transfer Efficiency during Battery Charging via Wireless Power Transfer

Electric vehicles are charged via wired charging, battery swapping, and wireless charging methods. Wired charging is vulnerable to cable damage and adverse weather conditions. The primary issues with battery swapping are cost and battery accumulation. Wireless charging eliminates cable mess and provides drivers with a safe, autonomous charging opportunity. However, wireless charging efficiency is not yet at the desired level. In this study, the aim is to increase the efficiency of wireless power transfer, with a focus on the compensation system in which the transfer takes place. Coils with circular and double-D geometries were designed, and tests were conducted at different duty cycles and air gaps. The efficiency was examined by adding a core and shield to the compensation system. Subsequently, the material-sensor system that gave the project its novelty was included in the compensation system. The effects on transfer efficiency were investigated using four different materials and two pressure sensors. As a result of the experiments, a maximum efficiency of 82.38% was achieved with the foam material placed between the circular coils, using an air gap of 55 mm. Final tests were performed with a lithium-ion battery pack. Batteries were charged at 0.2, 0.5, and 1.0C ratios. The average efficiencies at these C ratios were recorded as 82.89%, 76.25%, and 61.93%, respectively. Simulation studies were carried out in MATLAB and Ansys programs, and the developed models were verified.
