What is the basic composition of the communication charging station motherboard?

The basic composition of the AC charging pile's mainboard mainly includes the following parts:

1. Main control module

The main control module is the core of the AC charging pile's mainboard, equivalent to the "brain" of the charging pile. It is responsible for controlling the charging pile's workflow, monitoring various parameters during the charging process, processing commands from users, and correspondingly controlling the operation of the AC charging pile. It typically includes a central processing unit (CPU), memory, clock, and other necessary integrated circuits.

2. Power module

The power module is responsible for converting the input AC power into DC power suitable for various modules. It employs switching power supply technology, encompassing filtering, rectification, DC-DC conversion, and other processes. It may be designed with multiple outputs to meet the varying requirements of different modules regarding power supply voltage and power. It provides a stable power supply for other components of the charging station.

3. Charging control module

The charging control module is connected to other electronic components on the AC charging station's main board to control the entire charging process. It is responsible for identifying the vehicle model, confirming the charging requirements, determining the appropriate charging method and charging power, and monitoring various parameters during the charging process, such as charging current and voltage.

4. Communication module

The communication module facilitates communication between the main control board and external devices, such as the vehicle battery management system (BMS), back-end management system, user terminals, etc. Common communication interfaces include CAN bus, RS485, Ethernet, 4G/5G, Bluetooth, etc. This module is primarily responsible for transmitting data from the AC charging station to the back-end server or mobile devices, enabling remote monitoring and management.

5. Security protection module

The safety protection module is responsible for ensuring the safety and reliability of the charging process. It can detect data such as battery charge level, voltage, and temperature during the charging process, and ensures the safety of the vehicle and user through system control. It includes functions such as leakage protection, overcurrent protection, and overvoltage protection.

6. Sensor module

The sensor module can collect various data from the environment where the AC charging station's mainboard is located, such as temperature, humidity, and combustible gas concentration. This data can be used to optimize the efficiency of the AC charging station, ensuring the safety, reliability, and efficiency of the entire charging process.

7. Interface module

The task of the interface module is to connect the charging pile with the charging equipment. It provides different interfaces according to different charging equipment, such as USB interface, Bluetooth interface, etc., making charging more convenient and efficient.

8. Relay module

The relay module is responsible for controlling the working state of the charging pile. Its working mode can be adjusted according to user requirements, thus achieving automatic and manual control of the charging pile.

9. Metering unit

The metering unit is used to measure the amount of electricity consumed during the charging process, ensuring the accuracy of billing. It is typically implemented using a high-precision metering chip.

10. Display and operation module

The display and operation module includes a display screen and operation buttons, which are used to display information such as the status of the charging pile, charging progress, and charging fees, and allow users to perform operations such as starting charging and setting charging parameters.

These components work together to ensure that the AC charging station can provide safe and efficient charging services for electric vehicles.

The AC charging pile mainboard from XinCheng Technology, innovatively composed of these modules, provides powerful performance and stability for the charging pile, setting a new paradigm in the charging field.
