1, the slow charge is the constant current mode of charging, and automatically converted to trickle charging after full; The fast charge generally uses pulse high current charging, and the polarization reaction in this process will cause the battery temperature to rise rapidly, which will have some impact on the battery life. But in fact, with the progress of the process, the impact of the fast charge process on the battery life has also been reduced.
2, the fast charging current is large, so the charging time will be much shorter; The charging current of slow charge is small, so the charging time is long.
1. Different technologies are used. The technology used in fast charging is generally high voltage or high current technology such as charge pump, double cell, and slow charging generally does not use these technologies.
2. The effect is different, taking the charging situation every 5 minutes as an example, fast charging can rush 15% of the power every 5 minutes, while slow charging can only rush 2% of the power every 5 minutes.
