Mobile phone chargers can be roughly divided into travel chargers, seat chargers, and maintenance chargers. Generally, users mainly come into contact with the first two types. The best-selling item on the market is the travel charger.
There are also various forms of travel chargers, including affordable duck egg mini travel chargers, regular desktop card type chargers, and high-end desktop chargers with LCD displays.
Mobile phone chargers, also known as mobile phone adapters, are actually composed of a stable power supply (mainly a stable power supply, providing stable working voltage and sufficient current) and necessary control circuits such as constant current, voltage limiting, and time limiting. The output parameters marked on the charger (referring to line charging), such as output 5.0V/1A, output 5.0V/1500mA-11200, refer to the relevant parameters of the internal voltage stabilizing power supply. By understanding this principle, you will know that a high-quality mobile phone charger can easily be replaced by a high-quality voltage regulator.
The charger for lithium-ion batteries commonly used in mobile phones adopts a constant current and voltage limiting charging system, with a charging current generally around C2, which is a two-hour charging rate. For example, a 500mAh battery can be charged at 250mA for about two hours to reach 4. Charge at a constant voltage after 2V.
Lion batteries are not suitable for using the - DV/DT detection fast charging method used in NIMH advanced fast chargers, as lion batteries have strict limits on charging current. Lithium ions (Li+) are very active, and high current charging can easily cause danger.
