Abstract

Batteries have an important role in the development of energy needs. Good battery performance, will support the devices it supports. In addition to the current and voltage on the battery, the temperature also affects the performance of the battery such as overheating, short circuit or even an explosion in the battery. One aspect of battery monitoring is how the temperature inside the battery is always controlled. This will keep the battery always at the ideal temperature for optimal performance. The stages in software design consist of fuzzy logic design using microcontroller. The input used is a voltage sensor using a voltage divider circuit and a temperature sensor max6675 thermocouple type-k. To display the system readings, a liquid crystal display is used in the Arduino IDE software. In the calibration process the average error on the voltage sensor is 0.635%, the current sensor is 4.68% and the temperature sensor is 0.14%. On the performance of the battery in charging lithium ion batteries using the fuzzy logic control method in day and night conditions. At night conditions there is a decrease in temperature from 36.630C to 26.230C. Full charge voltage at 12.49 V with a long charge time of 6 hours 35 minutes. Meanwhile, during the day, the temperature increased from 30.910C to 38.270C. Full charge voltage at 12.33 V with a long charge time of 8 hours 54 minutes.

Additional Information:	Baterai memiliki peran penting dalam perkembangan kebutuhan energi. Performa baterai yang baik, mendukung perangkat yang didukungnya. Selain arus dan tegangan pada baterai suhu juga mempengaruhi kinerja baterai seperti overheat, short circuit atau bahkan ledakan pada baterai. Salah satu aspek dari monitoring baterai adalah bagaimana caranya suhu di dalam baterai selalu dikontrol. Ini menempatkan baterai selalu pada suhu yang ideal agar dapat bekerja secara optimal. Tahapan dalam perancangan perangkat lunak terdiri dari perancangan fuzzy logic yang menggunakan mikrokontroller. Input yang digunakan adalah sensor tegangan menggunakan rangkaian pembagi tegangan dan sensor suhu max6675 thermocouple type-k. digunakan untuk menampilkan hasil pembacaan sistem, liquid crystal display digunakan dalam perangkat lunak Arduino IDE. Pada proses kalibrasi rata-rata error pada sensor tegangan 0,635%, sensor arus 4,68% dan sensor suhu 0,14%. Pada kinerja baterai pada charging baterai lithium ion menggunakan metode fuzzy logic control pada kondisi siang dan malam hari. Pada kondisi malam terjadi penurunan suhu 36,630C sampai 26,230C. Tegangan full charge pada 12,49 V dengan lama waktu charge 6 Jam 35 menit. Sedangkan Pada kondisi siang hari terjadi kenaikan suhu 30,910C sampai 38,270C. Tegangan full charge pada 12,33 V dengan lama waktu charge 8 Jam 54 menit.
