What Causes the Grounding Fault Display During New Energy Vehicle Charging?

[VanOscar]

New energy vehicles displaying a grounding fault during charging may be due to the installed grounding bar failing to meet the charging pile equipment requirements. Solutions for grounding faults: If at a public charging station, call the official customer service hotline and wait for repairs, prioritizing other available charging equipment; For residential property owners, it's advisable to contact the property's electrician for troubleshooting; For owners in older residential buildings, first check if the nuts at the grounding device connection are tightened and whether there is any rust. If nuts are loose or rusted, retighten them and remove rust from affected areas to ensure grounding safety. Charging precautions: For new vehicles, completely deplete the battery before the first charge, then charge it fully—preferably for up to 12 hours to enhance battery performance. During regular charging, avoid excessively long charging times; around 7 hours is generally sufficient to prevent battery damage. Prolonged charging may cause the battery to swell. If this occurs, discontinue use immediately to avoid potential hazards like explosions.
