What Causes the Fault Light on a New Energy Charger to Flash?
2 Answers
New energy charger fault light flashing is due to the household socket not having a ground wire. The home portable charging gun provided by the 4S store must be plugged into a socket with a ground wire to charge properly. Since cars heavily rely on batteries, all vehicles have a battery indicator on the dashboard. If there is a fault in the charging system, an alarm will be triggered. Below are the benefits of new energy vehicles: 1. Fuel savings: New energy vehicles generally use natural gas, petroleum gas, hydrogen, or electricity as power sources, saving fuel energy. 2. Reduced exhaust emissions: New energy vehicles produce no exhaust emissions, effectively protecting the environment. Electric vehicles generate no tailpipe emissions and cause no pollution. Hydrogen-powered vehicles emit only water, posing no environmental pollution. Because they are essentially zero-emission, they are also exempt from license plate restrictions. 3. High efficiency: New energy vehicles typically employ new technologies and structures, making them more efficient.
I've been driving a new energy vehicle for a while and have encountered several instances where the charger's fault light was flashing. The most common reason is unstable power supply, such as fluctuating socket voltage or insufficient power supply at the charging station, which triggers the charger's protection mode and causes the alarm light to flash. Another possibility is poor contact, where the plug isn't inserted tightly or the interface is worn, leading to inadequate current conduction and directly prompting the light to flash. Sometimes, the issue lies with the charger's internal components, like a short circuit or aging circuit board, especially in hot weather, which can more easily trigger overheating protection and cause the light to flash. Once, during summer outdoor charging, I noticed the light flashing and found that the fuse had blown—replacing it quickly solved the problem. Another factor could be a software glitch, particularly in models with automatic charging control, which may require a restart or firmware update to resolve. In any case, don't force it to work; first, check the plug and power supply. If that doesn't help, contact after-sales service for a diagnostic scan to avoid damaging the battery or causing safety hazards.
