Abstract

Konversi mobil konvensional (ICE) ke mobil listrik (BEV) adalah solusi peningkatan jumlah kendaraan listrik yang lebih murah daripada membeli mobil listrik baru. Perancangan tata letak komponen menentukan stabilitas kendaraan hasil konversi, sehingga harus dilakukan berdasarkan rangkaian analisis dan perhitungan yang mana sangatlah kompleks, sehingga menyulitkan para pelaku bengkel konversi mobil. Pada tugas akhir ini, dibuat sebuah antarmuka pengguna grafis yang berfungsi sebagai alat bantu perhitungan pusat massa dan stabilitas dalam metodologi konversi mobil ICE ke BEV menggunakan MATLAB App Designer.
Metode pada aplikasi ini menggunakan masukan aplikasi yang terdiri dari spesifikasi mobil ICE, spesifikasi komponen BEV, dan tata letak komponen BEV. Luaran aplikasi adalah pusat massa dan stabilitas dari mobil ICE dan BEV. Perhitungan pusat massa diprogram dalam MATLAB App Designer. Sedangkan analisis stabilitas yang mencakup slip, skid, dan guling disimulasikan menggunakan permodelan Simulink. Luaran stabilitas adalah batas kecepatan belok atau cornering limit pada variasi sudut belok roda depan (steering angle).
Hasil dari penelitian ini adalah aplikasi metodologi konversi mobil ICE ke BEV yang mampu membantu dalam menentukan tata letak komponen BEV dengan parameter stabilitas. Pada aplikasi, dapat dilakukan pengujian 3 variasi tata letak battery pack, yaitu pembebanan posisi belakang, tengah, dan depan dengan posisi motor serta controller diletakkan pada bagian depan. Pada percobaan pembebanan tengah untuk konversi Toyota Calya, didapatkan bahwa CoG bergeser sebesar 5,34 cm ke belakang dan 8,55 cm ke bawah. Didapatkan kondisi kritis stabilitas berupa batas kecepatan belok pada variasi sudut belok 5°, 10°, 15°, 20°, 25°, dan 30° secara berturut-turut adalah 56,097 km/h; 40,053 km/h; 33,071 km/h; 29,002 km/h; 26,30 km/h; dan 24,38 km/h yang berarti stabilitas Calya BEV dengan pembebanan tengah cukuplah baik.

Converting conventional cars (ICE) to electric cars (BEV) is a solution for increasing the number of electric vehicles that is cheaper than buying a new electric car. The layout design of the components determines the stability of the converted vehicle, so it must be carried out based on a series of analyzes and calculations which are very complex, making it difficult for car conversion workshops. In this final project, a graphical user interface is created that functions as a tool for calculating the center of mass and stability in the ICE to BEV car conversion methodology using MATLAB App Designer. The method in this application uses application input consisting of ICE car specifications, BEV component specifications, and BEV component layout. The application output is the center of mass and stability of ICE and BEV cars. The calculation of the center of mass is programmed in the MATLAB App Designer. While the stability analysis which includes slip, skid, and roll is simulated using the Simulink model. The output of stability is the cornering limit on variations in the front wheel steering angle. The result of this research is the application for ICE to BEV car conversion methodology which is able to assist in determining the layout of BEV components with stability parameters. In the application, testing of 3 variations of the battery pack layout can be carried out, namely the rear, middle and front loading positions with the motor and controller positions placed on the front. In the middle loading experiment for the Toyota Calya conversion, it was found that the CoG shifted 5,34 cm backwards and 8,55 cm downwards. Obtained critical stability conditions in the form of cornering limits at variations of steering angle of 5°, 10°, 15°, 20°, 25°, and 30° respectively are 56,097 km/h; 40,053 km/h; 33,071 km/h; 29,002 km/h; 26,30km/h; and 24,38 km/h, which means that the stability of the Calya BEV with middle loading is quite good.
