How To Use Mobile Charger Correctly
Mar 31, 2018| Mobile phone chargers can roughly be divided into travel chargers, seat chargers, and maintenance chargers. The first two are usually touched by the user. The most widely sold products on the market are tour chargers. There are many ways to explore the chargers. There are common types of miniature travel chargers that are cheap and inexpensive. Usually, desktop card type chargers and high-end desktop chargers with LCD display are available. Device.
All mobile phone chargers are actually composed of a stable power supply (mainly a regulated power supply, supply of stable operating voltage, and satisfying current) plus necessary constant current, voltage limiting, and time-limited control circuits. The output parameters marked on the original charger (line charger) are, for example, 4.4V/1A output and 5.9V/400mA output. This refers to the relevant parameters of the internal regulated power supply. Understand this principle, you will know that a (good quality) mobile phone charger is simply changed to a high-quality regulated power supply!
Li-ion battery chargers for mobile phones use a constant-current, voltage-limited charging system. The charging current is usually about C2—that is, a two-hour charge rate. For example, a 500mAh battery uses 250mA to charge for about two hours. After 4.2V constant voltage charging.
The lion battery is not suitable for the fast charging method used by the NIMH battery for high-end fast chargers -DV/DT detection, because the lion battery has severe restrictions on the charging current. Lithium ion (Li+) is very vivid, high-current charging is very simple risk.
When charging your mobile phone for the first time, try to charge as long as possible - 3 hours is better. Avoid overcharging. Excessive battery charging to more than 100. Because of the danger of lithium battery overcharging, if you use the "overcharge charger", you also bought the device "a lithium battery with a rough quality protection circuit board", which is waiting for a fire when charging! Do not expose the battery Under high temperatures or severe cold, like a dog day, you should not put your mobile phone in your car, withstand the exposure of the hot sun, or get it in an air-conditioned room and place it in an air-conditioned place.
When charging, it is normal that the battery is a little hot, but it cannot be made "high fever". To prevent this from happening, it is good to charge at room temperature (around 26 degrees) and not to cover anything on the machine. Stay away from any Golden Letter items. Mobile phone batteries should avoid contact with gold and silver jewelry, watches, metal accessories, pins, etc. just in case. When the socket of a mobile phone battery encounters a conductor, a short circuit occurs, causing the temperature of the battery to rise. The high temperature causes the chemical substances in the battery to volatilize, resulting in a very dangerous gas. In severe cases, an explosion may occur. Do not recharge the battery when it is not used up. This will not only damage the battery but also shorten its useful life. You should develop a good habit of charging when you run out of electricity.
