The main types of AC charging station motherboards are as follows:

1、 Divided by functional integration level

     Highly integrated motherboard

• Features: It highly integrates multiple functions such as charging control, communication module, metering module, and protection circuit on one motherboard. This can reduce the number and volume of circuit boards, improve the stability and reliability of the system.

• Advantages: Easy installation, small space occupation, and relatively low cost. Due to high integration and better collaboration between various functional modules, more efficient charging control and management can be achieved.

• Applicable scenarios: Suitable for installation environments with limited space for charging stations, such as residential parking lots, commercial centers, etc.

    Modular motherboard

• Features: Different functional modules are designed as independent circuit boards and connected through interfaces to form a complete charging station system. For example, the charging control module, communication module, metering module, etc. can be made into independent circuit boards.

• Advantages: High flexibility, able to combine and upgrade modules according to different needs. If a module malfunctions, it can be replaced separately without replacing the entire motherboard, reducing maintenance costs.

• Applicable scenarios: Suitable for charging pile projects with high requirements for functional scalability, as well as occasions that require customization according to different regional standards and user needs.

2、 Divided by communication method

     Wired communication motherboard

• Features: Communicate with the backend management system through wired networks such as Ethernet, RS485, etc. This communication method is stable and reliable, with fast data transmission speed and strong anti-interference ability.

• Advantages: Suitable for occasions that require high communication stability, such as large charging stations, public parking lots, etc. It can achieve functions such as remote monitoring, data collection, and management.

• Disadvantages: Wiring is required, installation costs are high, and it is not easy to move and deploy flexibly.

    Wireless communication motherboard

• Features: It uses wireless communication technology (such as Wi Fi, Bluetooth, GPRS/3G/4G/5G, etc.) to communicate with the backend management system. This communication method does not require wiring, is easy to install, and has high flexibility.

• Advantages: Suitable for mobile charging stations, temporary charging points, and other occasions, it can be quickly deployed and used. Meanwhile, the development of wireless communication technology enables charging stations to achieve more intelligent functions, such as remote control and scheduled charging.

• Disadvantages: Communication stability may be affected by environmental factors such as signal interference, distance limitations, etc. The data transmission speed is relatively slow compared to wired communication.

3、 Divided by applicable voltage levels

     Single phase AC charging station motherboard

• Features: Suitable for single-phase 220V AC power supply, with an output power generally below 7kW. This type of charging station motherboard has a relatively simple structure, low cost, and is suitable for home users and small commercial places.

• Advantages: Easy installation, low requirements for the power grid. It can meet the daily charging needs of general electric vehicles.

• Applicable scenarios: family garages, residential parking spaces, small commercial shops, etc.

    Three phase AC charging station motherboard

• Features: Suitable for three-phase 380V AC power supply, with an output power generally above 21kW. This type of charging station motherboard requires higher voltage and current processing capabilities, and its structure is relatively complex.

• Advantages: Fast charging speed, suitable for the fast charging needs of large electric vehicles and commercial operation vehicles. It can improve the efficiency and economic benefits of charging stations.

• Applicable scenarios: public charging stations, logistics parks, bus parking lots, etc.
