Why does the charging of new energy vehicles keep disconnecting automatically?
2 Answers
New energy vehicles frequently disconnecting during charging is likely due to issues with the vehicle's electrical equipment, problems with the charging pile, or the vehicle being subjected to interference. The following is an introduction to new energy vehicles: 1. Introduction: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. 2. Categories: New energy vehicles include four major types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy (such as supercapacitors, flywheels, and other high-efficiency energy storage devices) vehicles. 3. Significance: The promotion of new energy vehicles is aimed at addressing environmental protection and oil crisis needs, reducing or abandoning the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines.
As an electric vehicle maintenance enthusiast, there are generally several situations where charging keeps automatically disconnecting. The most common issue is charging equipment compatibility problems, such as a mismatch between the home charging station and the vehicle's onboard system, where voltage fluctuations can trigger the protection mechanism to disconnect. On the vehicle side, it could be that the battery management module detects excessively high temperatures or abnormal current, automatically stopping charging to prevent overheating and battery damage. Wiring faults, such as loose plugs or poor contact due to oxidation, can also cause frequent interruptions. Software bugs are another reason, as some vehicle models may have compatibility errors after an upgrade. Suggested solutions: First, reinsert the charging gun to ensure it's securely fastened, and restart both the vehicle and charging station software. If the problem persists, use the vehicle's diagnostic port to check error codes or visit a professional shop to test battery health. In daily use, avoid prolonged charging in high outdoor temperatures and regularly inspect the charging port for dust and clean it.
