What is the reason for the flashing fault light on the charging pile?
3 Answers
The alternating flashing of the fault light on BYD charging piles is due to poor contact between the charging pile and the charging cable. Taking the BYD Qin as an example, the following are the specific details of the BYD Qin: 1. Body dimensions: The length, width, and height are 4765 mm, 1837 mm, and 1495 mm respectively, with a wheelbase of 2718 mm. 2. Powertrain: Equipped with a 1.5-liter naturally aspirated engine, this engine has a maximum power of 81 kW, reaching maximum power at 6000 rpm, and a maximum torque of 135 Nm, reaching maximum torque at 4500 rpm. This engine features multi-point fuel injection technology and uses an aluminum alloy cylinder head and block. 3. Suspension: The front suspension uses a MacPherson independent suspension, while the rear suspension uses a torsion beam non-independent suspension.
I've been driving electric vehicles for several years and have encountered charging pile flashing lights, which can have several causes. For example, if the charging connector isn't plugged in tightly, it can trigger flashing warning lights; or unstable power voltage, such as aging household sockets, can cause this issue. I remember last time I charged, I forgot to remove the car key, the dashboard displayed an error, and the lights kept flashing. Upon inspection, I found the connection cable was slightly loose. It could also be a fault with the charging pile itself, such as poor internal circuit contact or program errors, requiring a restart or system update. It's best to start with the simple steps: first, ensure the plug is secure, check the power cord for any damage, then restart the charging pile. If the lights still flash, don't force it, as it could pose safety risks. I recommend contacting the charging pile's customer service immediately—they have professional diagnostic tools. Don't be like me when I first started, messing around and nearly getting an electric shock.
I'm quite interested in automotive electrical systems. When a charging pile's light is flashing, it usually indicates several common issues: first, abnormal power input, where the input voltage is too high or too low, triggering the protection mechanism; second, communication interruption between the vehicle and the charging pile, possibly due to protocol incompatibility or cable damage; third, internal component failure, such as relay or current sensor malfunction. When troubleshooting, I usually refer to the fault codes in the device manual, matching the flashing pattern to identify the problem: rapid flashing may indicate a short circuit, while slow flashing suggests a grounding issue. Additionally, external factors like severe weather or frequent operation causing system overheating and rebooting should be considered. Operationally, turning off the charging pile's switch and waiting a few minutes before retrying is advisable; if necessary, use a multimeter to measure circuit voltage, but be cautious not to touch the wires directly. In critical situations, seeking professional help ensures safety and prevents further damage.
