Should You Power On First or Plug In First When Charging a New Energy Vehicle?
2 Answers
When charging a new energy vehicle, you should power on first and then plug in the charging gun. Here are some relevant extended information: 1. Charging: The number of charge-discharge cycles has no direct relationship with the lifespan of the power battery. The battery itself has no memory function. Timely charging and discharging can maintain good charge-discharge capability of the power battery. Charging immediately after winter use ensures the power battery remains at a relatively high temperature, avoiding the charging heating phase and effectively shortening charging time. 2. Storage: If the vehicle needs to be parked for a long time, first disconnect the negative terminal of the low-voltage battery. It is recommended to park the vehicle when the power battery's charge level is between 50%-80%, as power batteries have self-discharge characteristics. According to tests, there is an average power consumption of 4%-5% per month during parking. Additionally, perform a charge-discharge cycle every 1-2 months to avoid performance degradation caused by long-term parking.
As a veteran driver who has been using new energy vehicles for a long time, I must say the charging sequence is not something to be taken lightly. Generally, it's safest to plug in the gun first and then power on. Think about it—if the gun isn't properly connected when the current is instantly activated, there might be sparks or even damage to the charging port. I remember one time when I was in a hurry and powered on first, only to hear a 'pop' sound during charging, and the plug even got slightly burnt. Since then, I've developed a habit: first, align the gun firmly with the vehicle's port until I hear a click to confirm, and only then start the power. This small habit has saved me a lot of trouble, avoiding unnecessary repairs. Also, different car models might vary slightly, so it's best to refer to the manual, but most recommend this sequence. When parking, don't rush to unplug the gun either—always power off first before handling it safely.
