As a special power supply equipment for new energy electric vehicles, charging piles are connected to the GGD low-voltage distribution system of the station. They mainly provide safe charging services for all types of pure electric and hybrid vehicles, taking into account power protection, metering and charging, and intelligent management and control. 1. Electric energy supply: AC slow charging is suitable for long-term static power replenishment in private parking spaces and parks; DC fast charging is used to quickly replenish energy in public stations and logistics fleets, improving vehicle life in a short period of time and meeting emergency charging needs for commuting, operations, and travel. 2. Safety protection: Linkage with the vehicle battery management system in real time, it has multiple protections such as overvoltage, undervoltage, overload, short circuit, leakage, high temperature at the gun head, and automatic power outage when pulled out of the gun to protect the safety of power batteries, lines and personal life. 3. Metering and charging: Built-in high-precision metering module to accurately collect charging power, support swiping, scanning, and APP payment, adapt to commercial station charging operations, and record charging energy consumption data for convenient statistical accounting. 4. Intelligent operation and maintenance: Equipped with a 4G/network port communication module, it uploads voltage, current, equipment failure, and charging records to the management background, realizing remote monitoring, fault warning, scheduled start and stop, and reducing station operation and maintenance costs. 5. Supporting use in multiple scenarios: It can be installed separately in private parking spaces, or multiple centralized supporting box transformers and GGD distribution cabinets can form a large charging station, covering communities, shopping malls, high-speed service areas, logistics parks, bus stations and other scenarios.
