What is the reason for the continuous flashing of the BYD charging pile fault light?
3 Answers
The alternating flashing of the BYD charging pile fault light is caused by poor contact between the charging pile and the charging cable. The specific reasons are as follows: External reasons: The main external components of the charging pile include the card swiping area, display screen, charging gun, emergency stop button, indicator lights, etc. These components are prone to direct damage due to accidents or natural disasters. This type of loss can be compensated through property insurance claims. Internal reasons: The charging pile is a machine used to charge electric vehicles, and the machine itself may have inherent or potential defects. Various quality issues may arise during subsequent operations, leading to equipment failure. If such internal faults occur, please contact the charging pile's equipment supplier for repair and inspection, and address the fault hazard to avoid similar failures. The fault site of the electric vehicle charging pile may expose dangerous parts such as circuits, so it is necessary to contact professional electric vehicle charging pile maintenance personnel to clean up the site to avoid leaving other safety hazards.
Seeing the BYD charging pile's fault light flashing continuously, I think it's necessary to first check some common issues. The most common one is loose or damaged power cable connections, which can cause poor contact and trigger the indicator light to flash. It could also be that the temperature control device inside the charging pile detects overheating, such as under direct summer sunlight, where excessive temperatures automatically trigger the protection mode. Another possibility is unstable voltage; if there's an issue with the household power supply, like in old circuits where the charging current fluctuates, it may also cause the fault light to flash. Additionally, don’t forget to check if the charging gun head and vehicle interface are dusty or oxidized, as dirt can affect current transmission. As an experienced owner, I suggest your first step should be to check if the charging pile feels overheated—unplug the charging gun and wait for it to cool before trying again. If the problem persists, contact BYD after-sales service or a professional electrician to inspect internal components, such as the motherboard or sensors. Don’t ignore this small signal; it might indicate potential electrical risks, and early action can prevent damage to the vehicle's battery.
If the fault light on your BYD charging pile keeps flashing non-stop, I suspect it might be caused by a few simple reasons. For example, improperly plugging or unplugging during charging, or the charging gun not being securely inserted with the latch not properly engaged, causing the system to misinterpret it as a fault and flash frequently. Another common scenario is the activation of overload protection, such as when multiple high-power appliances are used simultaneously, exceeding the home's electrical capacity, prompting the charging pile to enter a safety mode to alert you. It could also be an issue with the vehicle, like a battery management system error or interrupted communication with the charging pile, causing abnormal indicator lights. I usually clean the plugs and interfaces regularly to avoid rust or dirt affecting the signal. Don’t panic when this happens—first, disconnect the power and restart; sometimes, the indicator light returns to normal after a reboot. If that doesn’t work, refer to BYD’s user manual, which provides common fault codes for guidance. In short, patiently checking common issues can save you a lot of trouble.
