devolo MultiNode LAN 4TE

Depending on the charging infrastructure project, the requirements for the communication network vary. Large installations have a dedicated energy management system. All charging stations are connected via the power rail to the central MultiNode LAN device and the energy management system or a gateway.

In smaller installations, a master/slave configuration of the charging stations is often used. The devolo MultiNode LAN is suitable for both scenarios.

Projects often start with just a few charging stations, according to current demand. This reduces the initial investment. However, future expansion should still be taken into account and prepared for as best as possible. By choosing powerline-based data communication, scaling can be implemented easily and quickly. By installing additional charging stations with integrated devolo MultiNode LAN, or adding more distribution boxes with a MultiNode LAN, the communication network grows accordingly. There is no need to lay new cables or install and connect Ethernet switches in the underground garage or parking area. Currently, more than 100 network nodes can be implemented within a single powerline network.

With the devolo MultiNode Manager, the PLC network can be installed, monitored, and updated. Once all MultiNode LAN devices are installed, the network setup on-site takes just a few minutes. The MultiNode LAN devices automatically connect in an optimized topology. Network configuration is limited to setting parameters for network access. After that, the network is secured and can, if necessary, be expanded with additional network segments. The MultiNode Manager enables remote monitoring of the network topology and the status of network connections. A standardized interface allows integration into an energy management system or cross-installation management systems.

• With the installation of the busbars and charging stations, the foundation for the data infrastructure is automatically established.
• Especially in parking lots with longer distances, PLC provides a real advantage over wireless solutions or laying data cables.
• With G.hn powerline technology, even the most remote charging station can be reached.

• Subsequent network expansions are possible without any construction work.
• Currently, over 100 network nodes are supported in a PLC network.

• Powerline communication is particularly well-suited to the structural conditions in the context of charging infrastructure.
• For wireless solutions, solid walls and fire doors pose an almost insurmountable obstacle.
• Powerline communication easily penetrates solid walls and can be used across multiple floors.

• The powerline network is self-organizing and automatically finds the optimal topology adapted to the physical conditions at all times.
• Moreover, unlike in Wi-Fi networks, there are no disruptions to the signal path caused by vehicles or people.

• The communication devices are built into the charging stations or distribution boxes, and are therefore protected against unauthorized access.
• Additional protection is provided by the standard AES-128 encryption. Attacks such as deauthentication (deauth) are also not possible in PLC networks.
