Battery swelling is a rare but serious issue in electric vehicles (EVs). It occurs when the lithium-ion cells in the battery pack expand due to overcharging, overheating, or manufacturing defects. Swollen batteries can lead to reduced performance, difficulty in charging, or in extreme cases, safety hazards like fire risk. Owners often notice the issue through unusual noises, dashboard warnings, or physical deformation of the battery casing. Manufacturers recommend immediate inspection if swelling is detected. Proper charging practices, avoiding extreme temperatures, and regular software updates can mitigate the risk. Discussions about battery swelling are common on EV forums, as users share experiences and solutions. Highlighting this problem provides potential owners with critical information about risks, maintenance, and what to look out for, making it a valuable topic for search traffic related to EV reliability and safety concerns.
