Fast Charging Means Adopting DC Fast Charger?

Fast charging is just a word that indicates the speed of charging. Different chargers and battery definitions have differences. As long as the charging method is shorter than the general charging time, it can be called fast charging. Under normal conditions, fast charging and conventional charging are divided according to the ratio of charging current to battery capacity. Charging current greater than 0.1C is called fast charging, and less than 0.1C is called general charging. So it's not that fast charging is DC charging.
