The composition and function of AC charging pile

It adopts wall-mounted installation method (floor-mounted installation is realized after the bracket is configured), and is mainly used in public buildings, residential area parking lots or charging stations. This product uses conductive charging to provide AC charging interfaces for electric vehicles. The product is installed outdoors. Waterproof and dustproof design, protection grade IP54, this product integrates charging interface, control unit, communication, billing and other components, adopts modular design, has the characteristics of convenient installation and debugging, simple operation and maintenance, etc.

The single-gun AC charging pile is designed based on GB/T 20234.1-2015 and GB/T 20234.2-2015.

Single-phase (1W+N+PE) AC power is connected to the charging system through three UK10N connectors. After being protected by a C-level lightning protector, the leakage protector is connected in series with the AC main circuit. After being protected by the leakage protector, the metering power is input. Watt-hour meter (optional for some configurations), after the AC output from the meter, it is input into the AC contactor, and the output side of the contactor is directly sent to the charging plug. The maximum output power of the AC charging pile is 7kW

Under normal circumstances, it works according to its predetermined parameters or user commands. The monitoring system can detect and control the working status of the entire charging pile, and user commands can be issued through the local setting interface, local PC software, and remote background. The electrical schematic diagram of the HPXIN 7kW single-plug AC charging pile is shown in the figure below.

site preparation

Reserve the cables and communication cables in advance, then drill holes and pre-embed expansion bolts according to the drawings, and then move the charging pile to a fixed position and fix the equipment.

Site Notes:

1) The single-gun AC charging pile should be installed on the center line of the installation location (or the center of the two parking spaces);

2) The venue needs to add protective facilities such as reflective strips or anti-collision fences;

3) Reserve nearby fire-fighting equipment (fire extinguishers or fire-fighting sand pools).
