Journal SINERGISINERGI Abstract

Vibration is an inevitable physical phenomenon; excessive and uncontrolled amounts of vibration can result in damage and system failure. In accordance with various automotive product certification standards, vehicle batteries or rechargeable electrical energy storage systems (REESS) must undergo a vibration test to assess their mechanical integrity. This study aims to broaden the perspective on vibration assessment by examining it during vehicle operation and assessing the protective capabilities of vehicle suspension against vibrations from damaged roads in two-wheeled electric motor vehicles. The proposed method involves installing an accelerometer on the battery pack body, which is placed in the battery compartment. The experimental setup involved conducting tests on a 125-meter track, with the vehicle traversing roads characterized by concrete cracks, uneven surfaces, and potholes. Two distinct speed variations were selected for analysis: 10 and 15 kilometers per hour. The results obtained from the Rion VA 12 portable vibration analyzer are presented as a plot of the fast Fourier transform (FFT) graph. The maximum acceleration recorded was 2.35 and 1.98 G at the same frequency of 7 hertz (Hz). This research method and result align with others, including those focused on assessing road damage, passenger comfort, and vehicle component damage, such as shock absorbers. In the future, the development of a vehicle battery support structure is anticipated to further minimize vibration disturbance by reducing the peak acceleration values depicted in the FFT graph. The minimization of incoming vibrations is expected to enhance the safety and durability of the battery pack.

Conclusion

Vibration is an inherent mechanical phenomenon that can cause structural damage when excessive.This research focused on a novel approach to vibration testing by conducting tests on the road, revealing a peak FFT value of 2.The findings align with previous studies, highlighting the importance of FFT analysis in various fields, including vehicle vibration.Future work should focus on improving the battery support structure to enhance safety by reducing peak acceleration values.

Future Research

Based on the findings of this study, several avenues for future research emerge. First, investigating the impact of different battery pack mounting configurations on vibration attenuation could lead to optimized designs for improved durability. Second, exploring the use of active vibration control systems, such as magnetorheological dampers, could offer a more dynamic approach to minimizing vibration transfer to the battery. Finally, a comprehensive study examining the long-term effects of road-induced vibrations on battery performance and lifespan is crucial for establishing robust certification standards and ensuring the reliability of electric vehicle batteries. These research directions, building upon the current work, will contribute to a deeper understanding of vibration dynamics in electric vehicles and ultimately enhance the safety and longevity of battery systems, requiring approximately 180 words to fully articulate these potential research endeavors.
