The difference between AC ev charger and DC ev charger, Which charger is better for EV?

1. AC ev charger

   1.1 Description

       Charging the power battery through the on-board charger, is low-powered and slow.

       AC charging pile connects the charging socket to the on-board charger to charge the power battery,  that only plays the role of controlling power supply, without charging module.

   1.2 Advantage

   Small size, easy to install, low price, slow charging has a certain protective effect on the car battery.

   1.3 Weakness

   Slow charging

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

   buses and logistics vehicles, and public charging piles for passenger cars.

3.AC & DC charging method

 AC & DC ev 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.
