Does Charging a New Energy Vehicle Without Turning It Off Have Any Impact?

[SanJohnny]

Charging a new energy vehicle without turning it off does have certain impacts on the vehicle. Below are precautions for charging at charging stations: 1. Keep the charging gun head clean and dry: Do not place flammable, explosive, or combustible materials, chemicals, or combustible vapors near the charging station; keep the charging gun head clean and dry. If it is dirty, wipe it with a clean, dry cloth. Never touch the charging gun core with your hands while it is electrified. 2. Do not disassemble arbitrarily: Do not attempt to disassemble, repair, or modify the charging station. If maintenance or modification is needed, please contact the staff. Improper operations may lead to damage, water leakage, or electric leakage.

Last time at the charging station, I saw someone trying to charge while starting the car, but the charging gun wouldn't insert at all. New energy vehicles are smartly designed - if you don't turn off the ignition, the power battery and charging system will conflict. The car thinks you want to drive away while the charging module tries to work, which often leads to charging failure or circuit overheating. I've personally seen error warnings pop up on the infotainment screen. Doing this long-term might damage the battery management system. For safety, always remember to shift to P gear and power off before charging - it's basic protection for your beloved vehicle. Playing music during charging is fine, but never keep the car in driving mode.

As an experienced driver, I once tried charging without turning off the engine. The dashboard was still lit up, and the charging station immediately reported an error and stopped working. The charging logic for new energy vehicles requires them to be in a dormant state; otherwise, the battery management module can become confused. It's like playing games while charging your phone—the temperature soars, and it won't charge properly. The manufacturer's manual clearly states that you must completely power off before plugging in the charging cable, or you might blow a fuse. I've seen onboard chargers short-circuit during repairs due to this, and the repair costs aren't cheap. Always turn off all power systems before charging.

The charging mechanism of new energy vehicles is designed to require the vehicle to be completely turned off. The management modes of the power battery during driving and charging are different. Not turning off the vehicle will trigger the system protection and directly interrupt the charging process. This may lead to charging port malfunctions, and the vehicle's computer is prone to misinterpreting data. It is recommended to develop the habit each time: shift to P gear, press the start button to power off, and then connect to the charging station. Neglecting this step will result in inefficient charging.

Once I was in a hurry and plugged in the charging cable without turning off the engine, which made the car beep an alarm. The salesperson told me that the battery system of new energy vehicles is quite delicate—it can only focus on one task at a time. Making it both standby and charge is like forcing someone to eat while sleeping. Not only does it fail to charge, but the onboard controller may also overheat and trigger protection. Since then, I always wait until the screen goes completely dark after parking before charging. Don’t forget to follow proper procedures, especially in rain or snow—touching the charging port with wet hands is dangerous. Safety always comes first.

When charging a modern new energy vehicle, the vehicle must be in a dormant state. If the engine is not turned off, the 12V auxiliary battery will still be supplying power, which can interfere with the high-voltage charging module. This common knowledge is often overlooked by many people, and in reality, it may cause wiring harness overheating or communication failures. A friend of mine had to visit the dealership for repairs because of this. The correct practice is to completely shut down the vehicle's power before initiating the charging process. Paying attention to the status of the charging port indicator light during regular use can help prevent accidents.
