The difference between flash charging and fast charging: 1, the charging speed is not the same, flash charging is faster. 2, the voltage is not the same when charging, flash charging is low voltage fast charging, fast charging is high voltage fast charging. 3, the heating degree of the mobile phone is not the same when charging, the flash charging temperature is low, and the fast charging temperature is high. 4, the security of the mobile phone is not the same when charging, flash charging is safer.
Flash charge is a company that has developed its own fast charging technology. In fact, flash charge is a type of fast charge, but mobile phone manufacturers in order to highlight the advantages of their own research and development of fast charge technology, they use a unique name.
Three elements of fast charge:
To realize the fast charging function on the mobile phone, three elements need to be met, and all three are indispensable. Charger, battery, charge IC. The charger needs to meet sufficient output current and output voltage, because the charger line has a large parasitic resistance, if you want to achieve a large charging current, the on-load output voltage of the charger needs to be higher.
The main differences are as follows:
1, the charging speed is not the same, flash charging is faster.
2, the voltage is not the same when charging, flash charging is low voltage fast charging, fast charging is high voltage fast charging.
3, the heating degree of the mobile phone is not the same when charging, the flash charging temperature is low, and the fast charging temperature is high.
4, the security of the mobile phone is not the same when charging, flash charging is safer.
In the past, people generally recognized: \"flash charge is a kind of fast charge.\"
Recently, China Mobile terminal laboratory for flash charge and fast charge two technologies for science: can be so in the head, fast charge = high voltage, flash charge = low voltage, obviously, although they can achieve fast charging, but the voltage and current are different, the impact on the mobile phone battery, circuit board is not the same
The concept of flash charge was first proposed by OPPO, five minutes of charge, 2 hours of talk. At first, it is called VOOC flash charge, which is different from ordinary fast charge, and this is a low voltage and high current fast charge.
The mainstream charging protocols such as :PD QC PPS MTK_PE fast charging rules are generally high-voltage and low-current schemes
