2. DC ev charger
2.1 Description
Directly charge the power battery with high power and fast charging. The DC charging post converts AC power to DC power and charges the EV battery directly through the charging jack.
There are multiple charging modules.
The input voltage of DC charging post is 380V, the power is usually above 60kw, and it only takes 20-150 minutes for a full charge.
2.2 Advantage
High power, fast charging, more intelligent
2.3 Weakness
High price

1.7 Application
DC charging piles are suitable for scenarios with high charging time requirements, such as charging stations for operating vehicles such as cabs,
buses and logistics vehicles, and public charging piles for passenger cars.
3.AC & DC charging method
The AC charging post is to take the AC power from the grid, through the car’s slow charging interface, through the car’s internal charger to convert the AC power into DC power, and then input into the battery. Therefore, AC charging will not damage the car’s battery, but has the effect of battery maintenance. The DC charging pile, on the other hand, converts AC power from the grid into DC power, which is delivered to the car’s fast charging port and directly into the battery for charging.

5. Which charger is better for EV？
In fact, the main difference between ac and dc charger is the speed of charging, and cost, dc cost is very high, the general family, parking spaces will not be used, DC is generally applied to the location with fast charging needs, so who is better, is not valid, fast charging = use DC.
