Is It Normal for Car Charging Cables to Heat Up?
2 Answers
Car charging cable heating is not normal. Specific reasons for heating: Battery life expiration: Battery products have a life cycle. If charging is no longer possible, battery life issues need to be considered. Generally, the battery life cycle is 2-3 years, and factors determining lifespan are mainly related to user habits. Fuse blown: If the internal fuse of the battery is blown, the battery cannot charge, and the fuse needs to be replaced. Poor contact at the interface: When there is poor contact between the fuse tube and the fuse holder, the battery may not charge fully or at all. Professional repair services are required to address issues of incomplete charging or failure to charge.
A couple of days ago, I also felt the charging cable getting warm when I plugged in, which startled me at first. After consulting a technician, I learned that slight warmth is normal since electric current generates heat. However, if it feels too hot to touch or you smell plastic, you should stop charging immediately. Common issues include loose plugs, poor socket contact, or low-quality cables. I later switched to a certified national standard cable, and now I check the temperature after each charge—it's usually just slightly warm. I also make sure to avoid direct sunlight during charging, as high temperatures can worsen the heating. It's similar to how a phone charger heats up during fast charging—the key is to ensure it stays within normal limits.
