Is There Any Problem with Unplugging a New Energy Vehicle During Charging?
3 Answers
Unplugging the charging gun during the charging process will not cause any problems, but it will stop the charging. You will need to swipe the card again and reinsert the charging gun to resume charging. Charging methods for new energy vehicles: 1. Slow charging: Suitable for onboard chargers and home wall-mounted charging piles, with relatively low current and power. The charging time usually takes 6-8 hours. 2. Fast charging: Includes charging stations and mobile charging vehicles. It mainly uses high current from non-onboard chargers to directly charge the battery, allowing the battery to reach about 80% charge in a short time. Generally, it takes about 1 hour to fully charge. 3. Wireless charging: This method automatically connects to the power grid for charging and discharging through wireless charging panels embedded in roads and parking spaces without using wires or cables. This charging method is convenient and safe but has not yet been mass-produced or widely used.
As someone with some knowledge of automotive technology, I believe unplugging during charging is not the optimal choice. The charging system of new energy vehicles relies on sophisticated software to control the charging curve. Forcibly disconnecting during charging may trigger error codes or affect the battery management system, especially during fast charging where voltage fluctuations are significant, potentially causing imbalances in battery cells. Over time, this can lead to battery capacity degradation and reduced range. I've personally witnessed instances of plug overheating or sparking, although safety systems mitigate the risks. It's still advisable to prioritize completing the charging cycle. If interruption is necessary, try to wait until the charging display stabilizes before proceeding. Additionally, checking the vehicle manual for hot-swap support settings provides extra assurance—prevention is always better than cure.
As just an average electric vehicle user, I've noticed that unplugging the charger mid-session during daily use doesn't seem to cause immediate harm, but doing it frequently leads to issues. A few times when I was in a hurry and unplugged abruptly, the car's system displayed warning lights, and a check-up revealed chaotic battery charging records. Later, I learned to use the app to remotely monitor the charge level, ensuring it reaches the target before ending the session. Frequent interruptions indeed accelerate battery degradation and affect range performance. Now, I plan charging times more wisely, like completing a full charge during off-peak electricity rate periods to minimize last-minute operations. The battery 'breathes' during charging, and interrupting it adds stress. Friends shared that slow charging is even less tolerant of interruptions, so I stay patient to ensure each charging session goes smoothly.
