The selection of charging piles for the construction of charging stations is mainly determined according to the application scenarios of charging stations, and we can subdivide it into the following application scenarios. The main ones are: 1. Self-use site station; 2. Public space station; 3. Special site station; 4. Public fast charging station; 5. Operate special stations.

1. Self-use site station: ①, not open to the public; ②, passenger models, private cars;

Recommended products: A. Low power slow charging (7kW charging pile); B, low power fast charge as auxiliary (20-40kW all-in-one machine);

2. Public site station: ①, free/fee open; ②, passenger models, private/operation;

Recommended products: A, 7kW AC pile; B, 20/40kW DC single-gun charging pile; C, 60/80kW dual gun DC charging pile; D, 120kW double gun integrated charging pile.

3. Special site station: ①, not open, private/official; ②, passenger models, less charging demand;

Recommended products: A, 7kW AC pile; B, 20/40kW single gun; C, 120kW double gun integrated charging pile.

4. Public fast charging station: ①, free open, private/operation; ②, passenger models, charging demand;

Recommended products: A, group charging pile + DC terminal; B, 120kW double gun integrated charging pile.

5. Operation of special stations: ①, not open to the public; ②, medium/bus models, single charge more (bus station); 3, multiple models, charging demand (logistics garden).Recommended products: A, group charging pile + DC terminal; B, 180kW-240kW dual gun integrated charging pile. C, 120kW double gun integrated charging pile.
