Why does the electric vehicle charger show a red light but make no sound?

This situation may be caused by a faulty charger that prevents charging, but it could also be due to a malfunction in the electric vehicle's battery. Below is some relevant information about electric vehicles: 1. Introduction: Electric vehicles first appeared on city streets in the 1880s, starting with trams, which were invented in 1881 by the German Werner von Siemens. At that time, trams had to run on fixed tracks because they relied on steel rails to form the power supply circuit, making them inconvenient in congested areas. 2. Classification: Electric vehicles are public transportation powered by electricity, with energy supplied from overhead power lines, and they are divided into two types: trolleybuses and trams.
I've repaired many electric vehicle charger issues. A red light without any sound usually indicates a fault. It could be the charger overheating and triggering its protection mechanism, which often happens during outdoor charging in summer. If the cooling fan is clogged with dust and stops spinning, poor heat dissipation will cause the red light. Another possibility is power socket issues - unstable voltage or poor contact preventing charging. Check if both the charging plug and vehicle port are securely connected without looseness. Another common cause is internal circuit short or component damage. In such cases, don't force charging as it poses safety risks. My suggestion is to unplug it first, let it cool for half an hour, then retry. If it still doesn't work, you'll need professional inspection or charger replacement at a repair shop. Regular maintenance includes keeping the charger clean and avoiding direct sunlight exposure. Always prioritize safety - never attempt to disassemble or repair internal components yourself due to high danger levels.
