The capacity planning of charging piles is restricted by many factors.

Energy storage charging pile can charge the negative pole from 100kW to 5 and 10MW projects. This means we can serve smaller systems, such as local fueling stations, up to larger ones associated with fleet charging for delivery services and bus depots.
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.
The structured shape of the charging pile is fixed, so the method to improve the stability is mainly to adjust the position of gravity centre of the box, or to increase the size of the bottom support surface of the box, on the premise of not changing the overall structure size. Mobile charging piles are fixed by wheel support.
Information display screen Some charging piles are equipped with information display screens, which can display information such as voltage, current, real-time power, temperature, charging time, etc. Some can also display the working status of each phase of the three-phase 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.
The simple instalment of mobile charging piles benefits for its convenient layout, while dynamic arrangements of those charging piles through mobile mode make up for the insufficient number of fixed charging piles, which meets the growing charging demand under the increasing popularity of electric vehicles.
Charging piles above 7kw require a 380V meter. As mentioned above, the choice should be based on the power of the vehicle's own charger, while considering expansion needs such as changing vehicles. The mainstream new energy vehicle brands now all support 7KW charging piles.
