What does 'Please check charging system' mean for BYD?
2 Answers
On-board charger malfunction. Replacing the charger will resolve the issue. When charging a BYD E6, the high-voltage distribution box under the sub-instrument panel is in operation, during which several 'click' sounds from relay engagement will occur; if equipped with an air-cooled on-board charging device, it will also be operational, and the cooling fan will produce a 'humming' sound during operation - both are normal conditions. The system will automatically stop charging when the power battery is fully charged. Relevant information about BYD is as follows: 1. Introduction: BYD is a Chinese automotive brand established in 1995, primarily manufacturing commercial and family cars as well as batteries. Starting with a team of just over 20 people, it grew to become the world's second-largest rechargeable battery manufacturer by 2003, the same year it established BYD Auto. 2. Logo meaning: The new BYD logo no longer uses the original blue-and-white color scheme. The design has been changed to an oval shape incorporating light and shadow elements. Significant changes have been made to the font arrangement and graphic colors, highlighting BYD Auto's innovation, technology, and corporate culture essence, infusing the BYD brand with new meaning and vitality.
Last time my BYD displayed this warning, a friend helped me check and found that the charging port had water ingress and oxidation, with the metal contacts turning green. I didn't pay attention while charging in the rain, and the port wasn't tightly closed, allowing rainwater to seep in and cause poor contact. Later, we sprayed some electronic cleaner on it, let it dry, and the issue was resolved. However, more common causes include the charging gun's locking mechanism getting stuck or the grounding wire of a home charging station becoming loose. I remember one time at a fast-charging station, after trying three different chargers and getting errors each time, we finally realized the charging station's voltage instability had triggered the protection mechanism. If the warning persists after restarting the vehicle, it's best not to force a charge and instead go directly to a 4S shop to read the fault codes for a safer approach. Always remember to check the port for any foreign objects before charging, and try to choose indoor charging stations during humid weather.
