The mobile phone charges speed, with charge head, line and chip of power source government are relevant. Charge the head decided to fill electric power, power is greater, charge rate is rapidder; Fill electrical wiring line fine, resistance is great, charge slow, calorific amount is large. Chip of power source government is used at monitoring to charge process.
Charge first " sing leading role "The head charging commonly on market is 5V/2A, 5V/1A charge first, namely 10W and 5W charge first, a lot of fill quickly can achieve 18W(9V/2A) , 40W(10V/4A) , filling electric power is to charge first a very main index, decided what the head can output to charge most high-power.
Rise charge speed has two kinds of kind, it is to heighten tension, 2 it is promotion electric current. Increase voltage to be able to bring calorific issue, quicken batteries ageing. Opposite for raise electric current to rely on chart quite, VOOC is filled quickly used pattern of low voltage tall electric current, the QC that connects high is filled quickly used at the same time increase voltage and electric current.
Fill electrical wiring " sing minor role "It is very important also to fill electrical wiring, the line grows resistance more bigger, so charge speed can be jumped over slow. According to the joule's law of physics of junior high school, q=I^2RT, the resistor of the quantity of heat that lead produces and electric current, lead becomes direct ratio. If fill electrical wiring finer, longer, can produce much quantity of heat so, the likelihood poses safe hidden danger.
Commonly used data line can have 4 core commonly, green white two core are used at transmitting data, two core use Hei Gong at power supply. Fill line need and news report of chip of power source government quickly, because this has 7 core at least, among them two core are in charge of charging the communication of head and chip of source control of mobile phone report, talk things over fill electric power to wait.
Charge online monitorIf be opposite,charge head, fill electrical wiring to not be at ease, can buying " USB electric current monitors appearance " , on some treasure 20 yuan or so. Can to charging the process charges mediumly voltage, electric current, power undertakes monitoring, also can use at monitoring batteries health to spend, charge treasure whether empty mark.
Anyhow, charging speed and charge head, fill chip of source control of report of electrical wiring, mobile phone to concern, 3 person supplement each other, be short of one cannot. Accordingly, charge to select former plant as far as possible at ordinary times charge head, fill electrical wiring.
