“…Farklı bir çalışmada voltajların eşitlenme süresini azaltan yöntem denenmiştir [15]. Bulanık mantık kullanan yöntemler de mevcuttur [16][17][18][19][20]. Pilin şarj verimliliğini artıran ancak şarj etmek için daha fazla zaman gerektiren bir yöntem önerilmiştir ve şarj süresini iyileştirmek için Taguchi yöntemi uygulanmıştır.…”

Bataryalar elektrik enerjisini elektrokimyasal enerjiye dönüştürerek depolayabilen yapılardır. Şarj akımının ayarlanması bataryalarda önemli bir husustur. Yüksek akımla şarj bataryaların kısa sürede şarj olmasını sağlar. Batarya şarj kapasitesi sıcaklığa ve akıma bağlı olarak değişmektedir. Batarya şarj akım değerini ayarlayan birçok çalışma arasında bulanık mantık kullanan çalışmalar da mevcuttur. Bu çalışmada, Lityum İyon pil şarjında bulanık mantığı kullanan bir yöntem önerilmektedir. Pil yüzey sıcaklığını ve ortam sıcaklığını giriş olarak alan ve çıkış akımını belirleyen bulanık bir denetleyici tasarlanmıştır. Panasonic NCR-18650B Lityum İyon pil üzerinde denemeler yapılmış ve sonuçlar bilgisayara ayarlanabilir akım gerilim cihazı ile aktarılmıştır. 5°C, 23°C ve 36°C ortam sıcaklığında test edilen pilin şarj kapasitesinde sırasıyla % 0,2; 2,5; 1,2 oranında kazanç sağlanmıştır.

“…However, the periodic pulse charging current seems to be harmful to Li-ion batteries [23]. Other extended charging strategies, such as fuzzy control, neural network, sinusoidal ripple current charging, etc., are proposed and intended to improve the charging performance [24][25][26]. However, these extended charging strategies usually require complicated computing algorithms or accurate equivalent models of the Li-ion battery which would increase the complexity and difficulty of implementation.…”

In this study, a dual-output converter with a wide input voltage range is proposed for directly equalized charging of series-connected batteries without additional power conversion losses. Compared with most of the equalized charging topologies, such as the those with a multi-winding transformer or voltage multiplier, the proposed converter could be applied to different voltage conversion ratio applications. The proposed converter is capable not only of step-down but also step-up/down power conversions for different input voltage levels. By operating in discontinuous conduction mode, the diode reverse recovery losses can be eliminated and operation stability can also be enhanced. The operation principles and design criteria are both illustrated. A prototype of charging two series-connected LiFePO4 batteries is constructed. Corresponding experimental results of different input voltage levels are provided to verify the performance and validity.

“…From CC-CV side of view, there are many control systems have been proposed in order to control the CC-CV process successfully and smoothly. Fuzzy controlled system proposed by Guan-Chyun et al [10] had successfully improved CV stage but the method proposed is complicated, Jiann-Jong and et al [11] have built battery charger using CC-CV but the circuit is quite complicated and involves many auxiliary circuits. Min, C. and G. A. Rincon-Mora [12] also using CC-CV charging algorithm and improve the efficiency and charging time but the circuit proposed is using analog components which can suffer from unstable internal resistance of lithium battery.…”

“…Min, C. and G. A. Rincon-Mora [12] also using CC-CV charging algorithm and improve the efficiency and charging time but the circuit proposed is using analog components which can suffer from unstable internal resistance of lithium battery. Most of the chargers focus on improvement of charging time, accuracy, and efficiency of the charger [10][11][12][13][14]. As the result either the method or the circuit become complicated.…”
