Is it okay to unplug the charging cable before the new energy vehicle is fully charged?
2 Answers
Occasionally doing this a few times will not have much impact on the vehicle, it just means the battery misses a few balancing cycles. However, doing this frequently over time may damage the car battery. Charging methods for new energy vehicles: To date, there are only two charging methods for new energy vehicles: fast charging and slow charging. Fast charging and slow charging are relative concepts. Generally, fast charging refers to high-power DC charging, and most new energy vehicles that support fast charging can reach 80% capacity in about half an hour. Slow charging is simply AC charging, and the charging process usually takes 6 to 8 hours. Charging precautions: Extremely low battery levels can easily cause the power battery to become undercharged, and long-term undercharging can severely damage the power battery. When using an electric vehicle, it is best to practice shallow charging and discharging, and to charge frequently.
As a veteran driver of new energy vehicles, I often unplug the charger before the battery is fully charged. It's completely fine because modern electric vehicle batteries are designed intelligently. Lithium batteries perform best with shallow charging and discharging, and engineers recommend charging to around 80% for daily use to extend battery life by several years. If you unplug halfway, the car won’t have any issues—the battery management system automatically balances the cells. In fact, fully charging it every time can accelerate aging. After three years of use, with an average of two days a week not fully charged, my battery health still shows excellent condition. Another benefit is saving time. For example, if I’m in a hurry to get to work in the morning and the app shows 60% charge, I just drive off without being late. As long as you avoid frequently discharging to 0% or leaving it at full charge for extended periods, daily use won’t cause problems. Remember to use the original charger and perform regular battery calibrations—this ensures peace of mind and saves money.
