    One of the main reasons for these noises is the thermal expansion of the metal components of the vehicle's charging system, such as the connectors, cables, and internal components of the battery. When a battery is rapidly charged, it generates a significant amount of heat, which causes the metal components to expand.

    Why does a battery charger make a clicking sound?

    The charging mode is another reason a battery charger makes a clicking sound. The 12 and 6-amp modes are usually quiet and do not produce any clicking sound. However, a boost mode will produce a surge in current, leading to a clicking sound from the charger. Note that the boost mode is usually used when a car's battery is extremely low.

    Do EVs make noise when charging?

    Yes. Since all EVs are equipped with cooling systems to keep the batteries safe, you can expect some noise coming from all of them while charging. However, though the thunk sound is reported in almost all-electric cars, it is primarily associated with Teslas. Most users have shared their experience of hearing this noise while using Superchargers.
