The structure of the charging pile

The mechanism of the charging pile is composed of external hardware and internal hardware. Among them, external hardware includes charging guns, charging cabinets, wiring cabinets, connectors, cables, etc. Internal hardware includes inverters, transformers, rectifiers, low-voltage switches, relays, radiators, frequency converters, filters, etc. The charging module is the largest cost of the entire charging pile, and the charging module includes the above-mentioned inverter, transformer rectifier, etc.

The future development trend of charging piles

1. Bigger Faster Trend

Charging stations, especially public charging stations, require more power and faster charging time for Didi drivers. From the above component industry chain diagram, we can see that the key factor for increased power is the improvement of IGBT. If silicon carbide material is used, it can carry greater current and voltage. 

2. Connectivity Trends

The "interconnection" of charging piles is a key way to improve the convenience of charging pile users and improve the social charging network, including the interconnection of charging interfaces, the interconnection of charging transaction settlement, and the interconnection of charging service information.

The interconnection of charging piles covers three levels:

(1) The interconnection of the charging interface, that is, the matching of the charging interface of the vehicle pile;

(2) Interconnection of charging transaction settlement;

(3) Interconnection of charging service information.

Charging Pile Relay Introduce:

The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
