Why Does the Electric Car Stop Charging After a Few Minutes?
3 Answers
The reasons why an electric car stops charging after a few minutes include poor plug contact and aging or damaged batteries. Below are the detailed explanations: 1. Poor Plug Contact: If the connection between the plug and socket is not tight enough, it can lead to poor contact, resulting in the phenomenon of charging for a short while and then stopping. Solution: Unplug and reinsert the plug firmly. 2. Aging or Damaged Battery: With usage, batteries will inevitably age and deteriorate. The capacity of the battery gradually decreases over time, especially if improper use causes severe internal "sulfation." Such batteries exhibit the behavior of "quickly filling up when charging and quickly depleting when in use." During charging, the voltage rises rapidly, so it appears fully charged quickly, but during use, the voltage drops rapidly, leading to quick depletion. Essentially, such batteries cannot be repaired, and their performance deteriorates as a whole when aged. Solution: Replace the entire battery pack.
I encountered a similar issue last time when charging my electric vehicle—it automatically stopped just minutes after plugging in. Later, I identified several common causes: the charging gun port wasn't securely locked, leading to poor contact, or the charging station itself was faulty; if the battery temperature is too high during charging, such as immediately charging after the car has been exposed to intense summer heat, the system will automatically pause charging to protect the battery; the vehicle's charging settings might have a specific time or charge limit configured, stopping once reached; worn or aged charging cables can also interrupt power supply. I recommend re-plugging the charging gun, trying a different charging station, and letting the vehicle cool in the shade for half an hour before charging again. If the issue persists, it's necessary to check if the vehicle's BMS system is falsely reporting a fault.
When encountering charging interruptions, I usually analyze from three perspectives: First is hardware connection issues, where wear on the charging gun latch or dust in the interface can cause looseness. Second is vehicle status, such as the battery management system detecting abnormal single-cell voltage, or cooling fan failure triggering high-temperature alerts. Lastly are charging environmental factors, where unstable grid voltage or power fluctuations during peak usage can activate power-off protection. I've noticed some owners experience this issue more frequently with aftermarket chargers. Simple troubleshooting methods include cleaning charging port dust, checking vehicle charging records via mobile app, and restarting the charging station. Most minor issues can be resolved independently, unless frequent power interruptions occur, which would require after-sales battery module inspection.
