How many volts does an AC charging pile need?
AC charging piles are generally divided into 3.5kw, 7KW, 11kw, and 22KW specifications according to power. The more precise definition of the 7KW specification is 220V/32A/7kw, which is also the most common specification at present. Charging piles above 7kw require a 380V meter.
What is an AC charging pile?
Therefore, the AC charging pile can be understood as a set of connection and control equipment with a protection system. It implements a unified electrical protocol (national standard regulations) to communicate with the on-board charger to achieve functions such as opening and closing the scheduled charging.
What is the power of a charging pile?
Power and compatibility The power of a charging pile refers to the maximum amount of electrical energy that can be output per hour, in kW or "kilowatts". AC charging piles are generally divided into 3.5kw, 7KW, 11kw, and 22KW specifications according to power.
How does a car charging pile work?
From the external structure, the charging pile is clearly divided into components such as the pile body, cable, and charging gun head. At first glance, it seems that the charging pile performs the charging work, but for the AC charging pile, the real charging process is completed by the on-board charger (OBC) built into the car.
