AI Customer Service$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means
AI Customer ServiceA low-profile, high-current, and low-loss inductor is another major hindrance for high-current battery charging. The flash charger is a system-level solution. The output voltage of the adaptor is adjustable based on the battery voltage and charging current, so the traditional 5-V or 9-V adapter could not be used. The 5-V or
Flash charging is to speed up the charging speed of the mobile phone through the form of low voltage and high current. Therefore, these two chargers should not be used randomly, or it will damage the battery to some extent.
Flash battery charging is a total solution that can be seen in Figure 3. It has two low R DS(on) field-effect transistors (FET) in the power circuit to reduce the conduction loss. The purpose of using two back-to-back FETs instead of one FET is to avoid the backflow from the battery to the adapter side.
Another major difference is that the flash charger does not need an inductor. A low-profile, high-current, and low-loss inductor is another major hindrance for high-current battery charging. The flash charger is a system-level solution.
1.Flash charging is to increase the charging current, and fast charging is to increase the charging voltage, but the essence of both is to increase the charging power, and the speed of the two charging methods is not much different. Flash charging is low voltage fast charging, and fast charging is under high voltage.
When the value of R and the battery voltage are known, the charge current can be controlled by adjusting the voltage drop from VBUS to VBAT. Compared to the linear charger, the major loss component is removed from the charger.
