Energy Storage Battery 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. The more precise definition of the 7KW specification is 220V/32A/7kw, which is also the most
