What to Do When the Charging Current of New Energy Vehicles is Low?

Check if the generator V-belt is slipping. Inspect the charging circuit, the contact between the brushes and the slip rings, the armature winding, and measure whether the diodes are functioning normally.
If my new energy vehicle charges with a low current, I would first check if the charging gun is securely plugged in and whether the cable shows signs of wear or bending, as a loose connection can affect the current. Then, I would inspect the socket—household sockets may have insufficient voltage or power capacity, so it’s best to try a dedicated charging station. If the current remains low, I’d check if the cable is aged or corroded from rain exposure, in which case replacing the cable promptly would solve the issue. Additionally, weather plays a significant role; in cold conditions, the battery temperature is low, leading to slower charging. I would preheat the vehicle or charge it in a heated garage. Lastly, I’d adjust the vehicle settings, such as switching the charging mode to fast charging in the car’s app or checking for software updates to avoid bugs limiting the current. If the issue persists, I’d promptly schedule a professional inspection at a 4S dealership to avoid prolonged damage to the battery lifespan, which is crucial for driving safety and battery health.
When encountering a situation with low charging current, I prioritize safety first and avoid hastily increasing the current to prevent equipment damage. I'll first test whether the socket voltage or charging station power meets the standard, as a regular household outlet may provide insufficient current. It's recommended to switch to a 220V professional socket or a reliable public charging station. Simultaneously, I'll inspect the charging cable's condition—if it's damaged or using an incorrect mode like Mode 2 (slow charging), I'll replace it immediately. Next, I'll check the vehicle side: poor battery condition can also reduce current, so I'll check the battery health via the app or run a diagnostic test. Temperature factors can't be ignored either—preheat the car before charging in cold weather and avoid charging in direct sunlight during high temperatures. If the issue persists, I'll back up relevant data like charging logs and seek help from a professional technician to ensure there are no hidden system faults.
