48v lithium battery powerwall.Will fast charging damage the mobile phone battery?

　　I often see an advertisement on TV that says "charge for five minutes and talk for two hours." In fact, this is misleading because there are many additional factors that determine the power consumption rate of a mobile phone. Charging for five minutes does not guarantee two hours of normal talk. , this situation can only be realized in theory, so even if it is fast charging technology, consumers must treat it rationally, and now smartphones generally only take a few hours to charge. In reality, fast charging is not very necessary.

　　I believe that when everyone buys a mobile phone, in addition to considering whether the appearance is beautiful and whether the functions are complete, the most common thing to worry about is the battery power and charging of the mobile phone. The flash charging mobile phones now on the market sound like they charge much faster than ordinary mobile phones, so they have attracted many friends to buy them. But what is the difference between this charging method and the charging method we usually use?

　　First of all, what we need to know is that there are three types of mobile phone charging, namely the new flash charging, ordinary charging, and fast charging. From the names alone, we can know that the difference between these types of charging lies in the charging speed. But in fact, the first and third types are both fast charging, so strictly speaking they cannot be divided into three types.

　　So when it comes to flash charging, which everyone is more concerned about, this technology actually lowers the voltage and increases the speed of current during the charging process, so that charging will be faster. What everyone is most familiar with is that OPPO mobile phones use this charging mode.

　　Although this method charges quickly, it also has certain disadvantages, because it consumes more energy than the normal charging mode, so it requires very high configuration and the cost will be higher. And if you want to charge in this way, you must use the charger as a set. Unlike other mobile phones, you can mix the charging cable and the charging head. So if the phone is out of power and you don’t bring a charger, it will be difficult to borrow it. It will be more troublesome.

　　Fast charging is a charging mode with very high voltage. Unlike flash charging, it does not require that much current. Its advantage is that its compatibility is very good, and charging is relatively fast, because the charging cable and charging head are not as strict as the other one. For example, if they are all regular Android phones, then everyone's chargers can be mixed and used, so it will be more convenient. In this way, the cost will be much less. And even if fast charging cannot be achieved on the mobile phone, it can still charge continuously, but the ordinary speed is not that fast.

　　In fact, the principle of fast charging is not difficult. I believe everyone is already familiar with it in high school physics class. If you want to make the battery charge quickly, you must increase its power. Only when the power is increased, the speed will become faster. If you want to increase the power, you can increase the voltage or current, so there are two modes of fast charging.
