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.

Slow charging due to low current requires troubleshooting basic issues first: Reconnect if the charging gun is not properly inserted or loose; replace the cable immediately if damaged or bent. Then check the power supply—ordinary sockets have limited power, so opt for high-quality charging equipment or dedicated charging stations. Vehicle settings are also crucial; try adjusting the charging options in the app to fast-charging mode. To prevent similar issues, I maintain regular cleaning of the charging port and update the vehicle software.

For small charging current, I would start with the charging equipment. For example, aging cables causing increased resistance and reduced current should be checked and replaced with high-quality new cables. Power adapter issues are also common—when socket voltage is low or overloaded, separate high-power devices to avoid interference. From the vehicle perspective, battery temperature affects charging speed; preheat in cold weather or switch to a suitable environment. Adjust charging limits via the APP, such as maximum current settings, to ensure accuracy. The key is to use data monitoring tools to test current value changes, helping identify the cause. If abnormal, schedule a repair appointment.

Facing minor current issues, I first ensure the charging gun is securely plugged in without looseness, and the cable appears normal without wear. Power supply problems such as insufficient socket voltage or using poor-quality extension cords can easily cause weak current, so I switch to a stable power source. On the vehicle side, I consider temperature effects on battery charging efficiency, parking in a warm place or preheating in cold weather. For long-term maintenance, I develop the habit of cleaning the charging port, regularly checking the cable for aging and replacing it if necessary. Finally, I adjust the vehicle's charging settings, such as turning off the energy-saving mode to increase speed. If the issue persists, I seek help from a service center to prevent deeper circuit faults.
