The communication protocols supported by the 11KW charging station motherboard mainly include the following:

CAN communication protocol: CAN stands for Controller Area Network, developed by German electrical company BOSCH and standardized through ISO11898 and ISO11519. It is a standard protocol for European automotive networks. In charging stations, the CAN protocol is used for communication between the charging station motherboard and the vehicle's battery management system (BMS). It has the characteristics of high performance and reliability, and can efficiently process a large number of messages with minimal CPU load. Through the CAN bus, the charging station can obtain real-time battery status information sent by the vehicle BMS, such as battery level, voltage, temperature, etc., and adjust the charging strategy based on this information.

OCPP communication protocol: OCPP stands for Open Charge Point Protocol, which is an open communication protocol for charging stations. Currently, common versions include OCPP 1.6 (JSON)/2.0, etc. This protocol is mainly used for communication between charging stations and backend management systems, supporting remote monitoring, management, and control functions of charging stations. Through the OCPP protocol, operators can achieve centralized management of charging stations, including remote start/stop charging, setting charging parameters, monitoring charging station status, collecting charging data, etc. At the same time, it is also convenient for users to interact with charging stations through mobile apps and other means, query charging information, schedule charging, etc

Modbus communication protocol: Modbus is a widely used communication protocol in the industrial field and also has certain applications in charging stations. It adopts a master-slave communication mode, supports physical interfaces such as RS485, and has the advantages of simplicity, reliability, and ease of implementation. The charging station motherboard can exchange data with other devices or systems through Modbus protocol, such as collecting electricity data with the meter and transmitting status information with the monitoring system, to achieve comprehensive monitoring and management of the operating status of the charging station

TCP/IP communication protocol: With the development of intelligent and networked charging stations, TCP/IP protocol has also been widely used in the communication of charging station motherboards. Through Ethernet or wireless networks, charging stations can be connected to cloud servers, remote monitoring centers, etc. using TCP/IP protocol to achieve more powerful remote control and data management functions. Users can access the status information of charging piles and control the charging process anytime and anywhere through the Internet. Operators can also conduct centralized management and data analysis on a large number of charging piles to improve the operation efficiency and service quality

Bluetooth communication protocol: Bluetooth technology can achieve short distance data transmission. In 11KW charging stations, it is mainly used for close interaction between users and charging stations, such as connecting to the charging station through Bluetooth on a mobile phone for quick parameter settings, status queries, and other operations. It does not rely on network connection, is convenient and fast, and improves the user experience

WiFi communication protocol: WiFi protocol allows the charging pile to access the local wireless network, and then connect with the Internet. Users can remotely control the charging pile through mobile phone APP. Operators can also remotely monitor and manage the charging pile, and can easily upgrade software and other operations. At the same time, charging piles in public places can provide users with free network services through WiFi, increasing user stickiness
