Components of communication billing module
The communication billing module of a DC charging pile is composed of the following components:
Main component
This is the brain of the DC charging pile, responsible for handling functions such as business metering and billing, platform connection and human-computer interaction. It is usually based on ARM+Linux architecture embedded computer, built-in 4G communication module, Bluetooth module, GPS& Beidou module, etc., support QT4.8.6 interface display, and use sqlite3.0 database for data processing.
The card reader is used for user identity verification and payment settlement, and supports contactless card swiping to facilitate users to settle charging charges .
Provides various wireless communication methods, including cellular mobile data (TD-LTE/FDD-LTE supporting 3G and 4G full network compatibility), WiFi (2.4GHz Wifi 802.11/b/g/n), and Bluetooth 4.0.
Power Supply Module
Provides a stable power supply for the entire communication billing module.
Measures the electrical energy consumption during the charging process, providing a basis for billing.
Non-Vehicle Charging Machine
Has AC/DC conversion functions and is the core device for achieving charging.
Includes device communication interfaces such as 433MHz, RS232, RS485, CAN bus, and wired network interface LAN RJ45 for data exchange with external devices and networks of the charging pile.
NFC Payment and Touch Keys
Provides convenient payment methods and user input operations.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
