EV charging is a simple and frequent operation in the daily life of modern car owners, but many car owners often make mistakes in this seemingly simple process, especially when it comes to the plug-in sequence. This article will delve into why EV charging requires the importance of plugging in the battery first, then plugging in the power source, and elaborating on the three potential consequences of not following the correct charging sequence.
The key to the strict requirements for the plug-in sequence in the EV charging process lies in the "voltage regulator" function inside the charger. A voltage regulator in a charger is a circuit that converts the input voltage into a stable output voltage using a stabilization circuit, which plays a crucial role in safe charging. The correct charging sequence is to insert the battery first and then the power supply, so that the small current output of the battery can start the voltage regulator and turn on the voltage stabilization function, so as to effectively cope with the impact of 220V large voltage and ensure the safety of electric vehicle charging.
If a car owner neglects the correct charging sequence, there are three potential consequences. The wrong charging sequence can damage the charger. When the voltage regulation function is not turned on, the charger cannot stabilize the converted DC power within a certain voltage range, which is affected by the large current, resulting in damage to the charger parts and the early end of life. This also means that chargers that could have been used for three or five years may not work properly as a result.
The wrong charging sequence can cause damage to the battery. The battery is one of the core components of electric vehicles, and the current without voltage regulation may form an inrush current, which will impact the battery, resulting in the detachment of the battery's active materials, damage to the lead plate, and ultimately greatly shorten the service life of the battery. Considering the relatively high cost of battery replacement, it is the responsibility of the car owner to ensure that the battery is not caused unnecessary damage during charging.
Finally, the wrong charging sequence can lead to safety hazards. The "ignition" during charging is likely to be the result of the regulator not being turned on, and while this is generally manageable, there is also a potential risk of spontaneous combustion. For car owners, this is a serious safety issue that can lead to more serious consequences.
In order to avoid the above potential consequences, it is the responsibility of the car owner to develop the habit of the correct charging sequence. The correct charging sequence is not a complicated operation, but a simple habit of life, and it is also the key to ensuring the safe charging of electric vehicles. The charging instructions usually clearly state that the battery should be plugged in first and then the power supply when charging the electric vehicle. This simple step ensures that the regulator is activated at the start of charging, providing the necessary safety during the charging process.
It's important to know the correct charging sequence, but it's even more important to put this knowledge into practice. Car owners should carefully read the charging instructions, have an in-depth understanding of the precautions in the charging process of electric vehicles, and always keep in mind the correct charging sequence. In daily life, car owners should avoid changing the charging sequence at will to avoid unnecessary damage to the charger and battery.
The correct EV charging sequence is not only key to maintaining the charger and battery life, but also to the overall safety of the charging process. It is the basic responsibility of every EV owner to develop the habit of the correct charging sequence, and through this small gesture, you can ensure that the EV charging process is more safe and reliable. Ultimately, proper charging habits can not only help save on repair and replacement costs, but also improve the overall performance and longevity of the electric vehicle.
