There are a few possible reasons why your Tesla might pop when charging.
- Expansion and contraction of metal components in the battery pack. As the battery pack heats up or cools down, the metal components inside may expand or contract slightly. This can cause a popping sound. This is a normal phenomenon and is not cause for concern.
- Gas bubbles forming in the battery electrolyte. When the battery is charging, gas bubbles can form in the electrolyte. These gas bubbles can sometimes pop, which can cause a popping sound. This is also a normal phenomenon and is not cause for concern.
- A loose or damaged connector. If one of the connectors between the charger and the battery pack is loose or damaged, it can cause a popping sound as the charger contacts or disconnects from the battery. This is not a normal phenomenon and should be investigated by a Tesla service technician.
- A problem with the battery management system. In rare cases, a problem with the battery management system can cause the battery to overheat. When the battery overheats, it can cause a popping sound. This is a serious problem and should be investigated by a Tesla service technician immediately.
