Abstract

Baterai merupakan salah satu komponen kunci pada kendaraan listrik. Sel baterai terdiri dari beberapa material aktif yang berupa anoda, katoda, dan elektrolit. Anoda bertugas melepaskan ion elektron yang kemudian dibawa oleh elektrolit menuju ke katoda, dan menghasilkan arus listrik. Ketiga material aktif tersebut dapat mengalami ekspansi dan kontraksi selama proses pengisian dan pengosongan baterai, sehingga dapat mempengaruhi dimensi dan bentuk baterai atau biasa disebut dengan deformasi. Penelitian ini menggunakan metode rekayasa teknik. Perancangan sistem monitoring deformasi menggunakan sensor strain gauge. Alat ini memiliki output berupa tampilan layar LCD, Lampu LED, Alarm dari Buzzer, dan Notifikasi Peringatan pada Smartphone. Pengujian prototipe dengan cara mengukur deformasi yang terjadi pada satu sel baterai lithium-ion 18650 saat kondisi overcharge, pengujian ini dilakukan dengan arus konstan 3 Amphere tipe fast charging. Pada penelitian ini disiapkan 4 sampel yang memiliki State of Charge (SOC) 0% dan 50%. Hasil penelitian menunjukkan bahwa pengujian overcharging baterai dengan sensor strain gauge dapat mendeteksi deformasi baterai. SOC 0% pengujian 1 baterai terdeteksi titik tertinggi deformasi baterai 17,53%, SOC 0% pengujian 2 baterai terdeteksi titik tertinggi deformasi baterai 14,15%, SOC 50% pengujian 1 baterai terdeteksi titik tertinggi deformasi baterai 27,21%, dan SOC 50% pengujian 2 baterai terdeteksi titik tertinggi deformasi baterai 26,86%. Kata Kunci: Baterai lithium, overcharge, strain gauge, deformasi. ***** Battery is one of the key components in electric vehicles. Battery cells consist of several active materials in the form of anode, cathode and electrolyte. The anode is tasked with releasing electron ions which are then carried by the electrolyte to the cathode, producing an electric current. These three active materials can experience expansion and contraction during battery charging and discharging, which can affect the dimensions and shape of the battery or what is usually called deformation. This research uses engineering methods. Design of a deformation monitoring system using a strain gauge sensor. This tool has output in the form of an LCD screen display, LED lights, alarms from buzzers, and Blynk notifications on smartphones. Testing the prototype by measuring the deformation that occurs in 1 18650 lithium-ion battery cell when it is overcharged, this test was carried out with a constant current of 3 Ampere fast charging type. Prepare 4 samples that have a State of Charge (SOC) of 0% and 50%. The results show that battery overcharging testing with a strain gauge sensor can detect battery deformation. SOC 0% test 1 battery detected the highest point of battery deformation 17.53%, SOC 0% test 2 battery detected the highest point of battery deformation 14.15%, SOC 50% test 1 battery detected the highest point battery deformation 27.21%, and SOC 50% test 2 batteries detected the highest point of battery deformation 26.86%. Keywords: Lithium battery, overcharge, strain gauge, deformation.
