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.
