6 FAQs about [New energy pure electric battery abnormal sound]

Does a pure electric vehicle have a good vibration and noise performance?

Can battery system fault diagnosis be used in real-world vehicles?

The research on battery system fault diagnosis for real-world vehicles is still in the initial stage. More vehicle data can be added to these researches with vehicle access to the platform and the accumulation of operation data. The study will become more and more perfect, and such ideas have excellent application prospects.

Why do hybrid electric vehicles make noise & vibrations?

Unstable clutch output also leads to drivetrain vibrations . A study of the noise and vibration characteristics of a two-motor hybrid electric vehicle in pure electric drive mode shows that the meshing of the compound planetary gearset gears is the main cause of the noise and vibration of the short planetary gear and small sun gear pair.

Do electric vehicles make a lot of noise?

Noise and vibration performance is an important component of automobile comfort, and is a factor that users consider in their vehicle purchases. Even though pure electric vehicles do not create the same amount of noise as vehicles with conventional engines, the noise of the electrical system is more emphasized.

What are the sources of electric vehicle noise?

According to a summary of previous research in the field of NVH, the sources responsible for electric vehicle noise vibrations and harnesses (NVH) fall primarily into several segments (Fig. 2)- electric motor noise, Mechanical and auxiliary system noise, tire/road noise and aerodynamic noise [36, 37].

Why is my EV battery not working?

This type of fault can arise from various simple yet critical reasons, such as aging of battery wiring, where insulation materials degrade over time, or EV collisions that physically damage the battery casing or wiring, causing the positive and negative terminals to come into direct contact [57, 58].
