1, flash charge is to improve the charging current, fast charge is to improve the charging voltage, but the essence of both are to improve the charging power, the two charging methods are not different in speed. Flash charge is low voltage fast charge, fast charge is high voltage fast charge.

2, fast charge and flash charge are the technology to speed up the charging speed of the battery, but the technical principle is slightly different. Fast charging is nothing more than increasing the power of charging. In the case of a certain battery capacity, increasing the power can reduce the charging time, the greater the power, the shorter the charging time. The flash charging temperature is low, and the fast charging temperature is high.

3, the charging speed is not the same, flash charging is faster. The most important difference is that the safety factor of flash charging is higher than that of fast charging
