Abstract
Saat ini perkembangan kendaraan listrik di Indonesia berkembang sangat pesat. Dari data yang dihimpun Kementerian Perhubungan (Kemenhub) mencatat kendaraan listrik di Indonesia berjumlah 81.525 unit pada pertengahan September 2021. Hal ini membuat Institut Teknologi Sepuluh Nopember meneliti dan mengembangkan tentang kendaraan elektrik roda dua. Dimana pada Automotive & Forensic Center STP ITS mengembangkan electric scooter yang bernama ”SKOEITS”. Electric Scooter ini menggunakan sumber energi dari baterai. Komponen baterai kendaraan listrik ini terdiri dari Battery Cell, Battery Module, dan Battery Pack. Desain casing battery pack yang tidak memadai akan menyebabkan banyak masalah seperti keretakan, kebisingan, atau getaran. Oleh karena itu, dibutuhkan sebuah uji karakteristik getaran battery pack untuk mengetahui ketahanan getaran supaya tidak terjadi kerusakan pada battery cell. Penggunaan uji karakteristik getaran ini menggunakan Electrodynamics Shaker dan Oscilloscope.
Pada penelitian tugas akhir kali ini dilakukan analisis respon percepatan menggunakan sine test, reduksi getaran menggunakan classical shock test, dan jumlah isolator terhadap frekuensi resonansi pada battery pack. Penelitian ini menggunakan variasi jumlah isolator yaitu 3 isolator dan 4 isolator dengan jenis polycal wire rope isolators. Selain itu, menggunakan electrodynamics shaker untuk mendapatkan nilai reduksi getaran pada battery pack dengan classical shock test dan pengaruh jumlah isolator terhadap frekuensi resonansi dengan sine test serta oscilloscope untuk mengetahui nilai respon percepatan pada battery pack dengan sein test.
Pada pengujian sine test untuk battery pack menggunakan oscilloscope mendapatkan nilai Root Mean Square (RMS) pada tanpa menggunakan polycal wire rope isolators sebesar 0.4118 m/s2, 3 polycal wire rope isolators sebesar 0.1660 m/s2, dan 4 polycal wire rope isolators sebesar 0.1516 m/s2. Selain itu, mendapatkan nilai reduksi terhadap root mean square pada 3 polycal wire rope isolators sebesar 59.68% dan pada 4 polycal wire rope isolators sebesar 63.18%. Pada pengujian classical shock test untuk battery pack menggunakan electrodynamics shaker mendapatkan nilai respon getaran tanpa menggunakan polycal wire rope isolators sebesar 1.2 V, 3 polycal wire rope isolators sebesar 0.9 V, dan 4 polycal wire rope isolators sebesar 0.8 V. Pada pengujian sine test untuk battery pack menggunakan electrodynamics shaker mendapatkan nilai frekuensi resonansi tanpa menggunakan polycal wire rope isolators sebesar 7.27 Hz, 3 polycal wire rope isolators sebesar 7.40 Hz, dan 4 polycal wire rope isolators sebesar 7.41 Hz. Casing battery pack menggunakan 3 dan 4 polycal wire rope isolators disarankan dibandingkan dengan material, jenis, dan jumlah lilitan yang berbeda dikarenakan untuk mengetahui material, jenis, dan jumlah lilitan yang paling efektif.

Currently, the development of electric vehicles in Indonesia is growing very rapidly. From data collected by the Ministry of Transportation (Kemenhub), it was recorded that electric vehicles in Indonesia numbered 81,525 units in mid-September 2021. This has led the Sepuluh Nopember Institute of Technology to research and develop two-wheeled electric vehicles. Where the Automotive & Forensic Center STP ITS developed an electric scooter called "SKOEITS". This Electric Scooter uses an energy source from a battery. The components of this electric vehicle battery consist of Battery Cell, Battery Module, and Battery Pack. An inadequate battery pack casing design will cause many problems such as cracks, noise, or vibration. Therefore, a battery pack vibration characteristic test is needed to determine the vibration resistance so that no damage occurs to the battery cell. The use of this vibration characteristic test uses Electrodynamics Shaker and Oscilloscope.
In this final project research, acceleration response analysis was conducted using sine test, vibration reduction using classical shock test, and the number of isolators to the resonance frequency on the battery pack. This study uses variations in the number of isolators, namely 3 isolators and 4 isolators with the type of polycal wire rope isolators. In addition, using an electrodynamics shaker to obtain the vibration reduction value on the battery pack with the classical shock test and the effect of the number of isolators on the resonance frequency with the sine test and an oscilloscope to determine the acceleration response value on the battery pack with the sein test.
In the sine test for battery pack using oscilloscope, the Root Mean Square (RMS) value was obtained without using polycal wire rope isolators of 0.4118 m/s2, 3 polycal wire rope isolators of 0.1660 m/s2, and 4 polycal wire rope isolators of 0.1516 m/s2. In addition, the reduction value of the root mean square on 3 polycal wire rope isolators was 59.68% and on 4 polycal wire rope isolators was 63.18%. In the classical shock test for battery packs using electrodynamics shaker, the vibration response value without using polycal wire rope isolators was 1.2 V, 3 polycal wire rope isolators were 0.9 V, and 4 polycal wire rope isolators were 0.8 V. In the sine test for battery packs using electrodynamics shaker, the resonance frequency value without using polycal wire rope isolators was 7.27 Hz, 3 polycal wire rope isolators were 7.40 Hz, and 4 polycal wire rope isolators were 7.41 Hz. Battery pack casings using 3 and 4 polycal wire rope isolators are recommended to be compared with different materials, types, and number of turns because it is to find out the most effective material, type, and number of turns.
