Abstract

Baterai adalah sel elektrokimia yang dapat menghasilkan energi listrik dari reaksi kimia. Baterai lithium-ion termasuk salah satu jenis baterai yang dapat diisi ulang. Dalam proses pengoperasian baterai terdapat potensi kegagalan berupa korsleting, overheat, hingga ledakan. Terutama pada proses pengisian baterai, umumnya baterai memiliki teknologi battery management system (BMS), namun ada kalanya BMS tersebut terjadi kerusakan sehingga tidak dapat memutus aliran listrik pada saat pengisian daya. Metode penelitian ini menggunakan metode desain eksperimental. Rancang bangun prototipe smoke detector menggunakan sensor MQ-7 yang dapat mendeteksi zat karbon monoksida (CO) dalam satuan part per million (ppm). Prototipe ini memiliki output berupa tampilan layar LCD, Lampu LED, Alarm dari Buzzer, dan Notifikasi Blynk pada smartphone. Pengujian prototipe ini dengan cara mengukur asap hasil ledakkan 1 sel baterai lithium-ion 18650 yang mengalami overcharge, pengujian ini dilakukan dengan mengisi daya baterai menggunakan arus konstan 3 Amphere tipe fast charging. Disiapkan 4 sampel yang memiliki State of Charge (SOC) 0% dan 50%. Hasil penelitian ini menunjukkan bahwa pengujian overcharging baterai menggunakan sensor MQ-7 dapat mendeteksi zat karbon monoksida dari asap hasil letupan baterai pada SOC 0% pengujian 1 baterai terdeteksi asap 115 ppm saat SOC baterai 512,5% (9,15V) pada suhu 97,25℃, SOC 0% pengujian 2 baterai terdeteksi asap 131,55 ppm saat SOC baterai 420,83% pada suhu 115,75℃. SOC 50% pengujian 1 baterai terdeteksi asap 27,14 ppm saat SOC baterai 189,16% pada suhu 107,5℃, dan SOC 50% pengujian 2 baterai terdeteksi asap 29,55 ppm saat SOC baterai 250% dan suhu 80,5℃. Hasil kalibrasi MQ-7 dengan CO-Meter menunjukkan error sebesar 2,25%. Kata kunci: Baterai lithium, overcharging, detektor asap, gas karbon monoksida ***** A battery is an electrochemical cell that can produce electrical energy from chemical reactions. Lithium-ion batteries are one type of rechargeable battery. In the process of battery operation, there are potential failures in the form of short circuit, overheat, and explosion. Especially in the battery charging process, batteries generally have battery management system (BMS) technology, but there are times when the BMS is damaged so that it cannot cut off electricity during charging. This research method uses an experimental design method. The design of the smoke detector prototype uses an MQ-7 sensor that can detect carbon monoxide (CO) in units of parts per million (ppm). This prototype has outputs in the form of an LCD screen display, LED lights, alarms from buzzers, and Blynk notifications on smartphones. Testing the smoke detector prototype by measuring the smoke from the explosion of 1 18650 lithium-ion battery cell that is overcharged, this test is carried out by charging the battery using a constant current of 3 Amphere type fast charging. Prepared 4 samples that have State of Charge (SOC) 0% and 50%. The results of this study indicate that the battery overcharging test using the MQ-7 sensor can detect carbon monoxide substances from smoke from battery explosions at 0% SOC test 1 battery detected smoke 115 ppm when the battery SOC was 512.5% (9.15V) at a temperature of 97.25 ℃, 0% SOC test 2 batteries detected smoke 131.55 ppm when the battery SOC was 420.83% at a temperature of 115.75 ℃. SOC 50% test 1 battery detected smoke 27.14 ppm when battery SOC 189.16% at 107.5℃, and SOC 50% test 2 battery detected smoke 29.55 ppm when battery SOC 250% and temperature 80.5℃. The calibration result of MQ-7 with CO-Meter shows an error of 2.25%. Keywords: Lithium battery, overcharging, smoke detector, carbon monoxide gas
