The difference between fast charge and AC slow charge
The equipment is different, the AC charging pile needs to be charged by the car charger, and the DC fast charging pile does not need this equipment.
Charging speed is different. There is a big difference in charging speed between the two, and a pure electric vehicle (ordinary battery capacity) needs 8 hours to be fully discharged through the AC charging pile, while it only takes 2 to 3 hours through the DC fast charging pile.
The fast charging capacity is different, the AC charging pile provides power input to the charger of the electric vehicle, because the power of the on-board charger is not large, so it is not fast charging.
Dc charging is characterized by high current, AC charging is characterized by high voltage.
