Before the first charge, the electric vehicle's battery should be used up, but not completely drained. When you first buy an electric vehicle, the battery won't be fully charged, but it won't be too low either, unless it's an old or low-quality battery. When using it, you should estimate the approximate range based on the seller's estimate to avoid running out of power or overcharging. When the battery indicator shows only one bar remaining, you should consider stopping riding and preparing to charge it.
How to charge a newly purchased electric vehicle for the first time and precautions.
The first charge should ideally be done during the day. Everyone knows that the battery should be fully charged on the first charge, but being fully charged doesn't mean overcharging. Charging during the day makes it easier to control the charging time, preventing overcharging and over-discharging of the battery on its first charge. This allows the initial chemical reactions within the battery to proceed normally.
Regarding the initial charging time, since the electric scooter battery has never undergone charging and discharging before leaving the factory, it's crucial to ensure its proper functioning. Generally, a charging time of 5-6 hours is sufficient to fully charge the battery. Subsequent uses can be charged for slightly longer periods. As mentioned above, charging during the day is recommended.
After the first charge, although it's not exactly the first charge, the second charge is still considered a new car charge. At this point, you can let the battery charge down to almost empty and then charge it for a long time. This charge can last for 8-9 or even 10 hours to allow the battery's chemical reaction to complete a full cycle. This is what the electric car dealer told me.
When charging an electric scooter for the first time, the charger may heat up very quickly and intensely. Therefore, especially in summer, do not place the charger on objects that are prone to heat and combustion, and it is best not to place it on the seat of the electric scooter to prevent fire. Many electric scooters have spontaneously combusted while charging, so please be careful.
1. Use the original charger.
Nowadays, most mobile phone chargers use universal interfaces, which leads us to be very casual when charging, using any charger we can find. In fact, although the charger interfaces are the same, their parameters are still very different. In particular, using inferior chargers can seriously damage the phone battery.
2. Use the original data cable.
Some people think that data cables are just wires and don't need to be cared about, but that's not the case. The resistance and materials of a standard data cable are rigorously tested and will not have any adverse effects. However, inferior data cables can damage the phone battery.
3. Do not charge your phone with a case on.
While phone cases look nice and protect your phone, you need to remove them when charging. Phones get hot while charging, and using a case while charging can hinder heat dissipation, which is bad for the battery.
4. Do not use a computer to charge your phone.
Some people like to charge their phones using a computer's USB port. However, the current from a computer's USB port is unstable and differs greatly from that of a charger, which can damage the battery.
5. Don't use your phone while it's charging.
Playing on your phone while charging is a very bad habit. Not only will it cause the battery to overheat and damage the phone, but it also increases the risk of danger. It's best to avoid doing it.
For a new phone battery, just avoid using off-brand chargers and charge it at normal room temperature when using it for the first time.
You should also pay a little attention to the first three charge and discharge cycles of a new mobile phone battery.
1. For the first three uses, it is recommended to fully charge and fully discharge the battery to activate it.
After receiving your new phone, it's best to leave the battery inside and fully charge it using the original charger that came with the phone (regardless of whether the original new battery has any remaining power). Once the phone screen displays that the battery is fully charged (100%), continue charging for another 0.5 to 1 hour. Then use the phone normally until the battery is completely depleted and the phone shuts down naturally. This constitutes one cycle. It's recommended to perform this cycle three times when using a new phone.
2. When using your phone normally, it's best to fully discharge and fully charge the battery.
Most modern smartphones display a remaining battery level indicator; additionally, when the battery level drops below 15%, the phone will display a "Connect charger required" message. If it's convenient to charge and you're not in a rush, you can continue using the phone until the remaining battery level reaches 6% to 8% before charging. This allows the chemical substances inside the battery to undergo a more complete discharge reaction.
After fully charging, if you're not in a hurry to use the phone, it's recommended to leave it connected to the charger for another 0.5 to 1 hour. Even though the phone's battery indicator shows 100%, the charger will continue to charge the phone with a small current while the phone remains connected. This is commonly known as "trickle charging." This allows the chemical substances inside the battery to undergo a more thorough charging reaction.
Of course, some people may worry that if they forget to unplug their phone from the charger, will the battery overcharge over a long period of time?
The answer is: There's absolutely no need to worry. Modern mobile phones have built-in current and voltage monitoring circuits that can completely eliminate overcharging; in addition, the phone battery or the circuitry connecting the battery inside the phone has circuits to prevent overcharging and over-discharging.
When a phone is fully charged and the charger is not disconnected, the phone's charging circuit will restart to charge the phone when the battery level drops to a certain point. This is equivalent to the phone battery completing one charge-discharge cycle.
