Ac charging mode belongs to fast charging, the charging process of AC pile mainly depends on the vehicle charger, the volume and power of the vehicle charger is limited, therefore, in most cases, it can only be slow charging.
Combined with the use of private passenger cars, this mode is in line with the needs of its low-frequency mode, and it is also good for the battery. General charging cars are alternating current.
Because AC can not directly charge the battery, there is no fast charge and slow charge. The charger can only charge the battery with DC power, and the fast charge and slow charge depend on the internal circuit of the charger.
