How to Connect Siemens EV Chargers to the Internet

Siemens EV chargers can be connected to the internet using various methods to enable remote management, diagnostics, and firmware updates. The connectivity options include:

LAN (Ethernet)

Provides a stable, wired connection ideal for larger installations like SICHARGE DC chargers. Most Siemens EV chargers come equipped with built-in Ethernet ports for wired internet connections, making Ethernet the most reliable method for ensuring stable connectivity. To set up, simply connect an Ethernet cable to the charger and configure its network settings through the user interface or web portal. This approach offers the highest uptime and supports the implementation of redundancies. For example, you can link all chargers to a centralized router with a dedicated wired internet connection, supplemented by SIM cards as a backup. Even in locations without wired internet access, a central router with SIM cards provides a dependable

Wi-Fi

An easier-to-install solution, suitable for small to medium setups, particularly for VersiCharge chargers. Some Siemens chargers offer Wi-Fi connectivity, which can be configured directly on the charger or using Siemens’s configuration tools. This option is cost-effective and particularly suitable for AC chargers, especially in scenarios where a wider coverage area is required, and additional wiring is impractical. However, Wi-Fi connections can be less reliable in larger areas due to potential signal interruptions, making it important to assess the network's range and stability before opting for this method.

Cellular Data

Available for specific models, providing flexibility when other options aren’t feasible.

For robust uptime and performance, particularly for larger installations like truck depots, a wired LAN connection is recommended. For smaller setups, Wi-Fi or cellular data can be used, with the flexibility to connect the chargers to a third-party OCPP backend.

Important Consideration: Changing connectivity from one method to another (e.g., switching from Wi-Fi to LAN) after commissioning may require recommissioning the charger to the OCPP backend.

Data Security for Siemens AC and DC chargers

When connecting Siemens chargers to the internet, it’s essential to implement basic data protection measures. Ensure that the chargers are running the latest software to support encryption and authentication features. Although cyberattacks on charging networks are rare, taking these precautions significantly reduces risk. Implementing these security measures is typically low-cost and requires minimal additional investment, making it a practical step for safeguarding your system. Verify which security profiles are supported by the charger to make the best decision.

Integrating Siemens Chargers with Remote Monitoring Software

Siemens chargers, such as the VersiCharge AC and SICHARGE DC, are OCPP-compliant, making them compatible with third-party remote monitoring software like Ampcontrol. This enables businesses to manage their charging infrastructure efficiently, track usage, and handle troubleshooting from a centralized platform.

The commissioning process for integrating Siemens chargers into remote monitoring software involves setting up the devices in Siemens Device Management or via an OCPP backend. When first connecting the chargers to a remote monitoring system, users need to ensure that their network setup is optimized to avoid issues during commissioning.

How to Connect Siemens EV Chargers to Monitoring Software

  1. Verify the Siemens charger supports the required OCPP version (e.g., OCPP 1.6 or OCPP 2.0.1).
  2. Obtain the backend URL and credentials for your monitoring platform such as Ampcontrol
  3. Update the OCPP settings through ABB support or directly via the charger’s interface or email the Siemens support. It is important to use the support of your country. Typically the support responds withing 24 hrs.
  4. Once the support confirmed or you were able to input the URL through the user interface, Reboot the charger and confirm the connection to the monitoring software.

Data Insights from Siemens Chargers

Siemens chargers offer valuable data insights to enhance fleet management. These include:

  • Error Codes: The chargers provide a detailed list of error codes that can help identify and resolve issues remotely. For example, common issues include connector lock failure, EV communication errors, and high temperature faults. These errors can be monitored in real-time via OCPP or remote systems.

  • Performance Data: Key metrics such as meter values, including voltage, current, power consumption, and energy usage, are available for analysis. This data can be used for load balancing and smart charging strategies, optimizing energy consumption across fleets.

Challenges in Remote Monitoring of Siemens EV Chargers

Siemens is generally known for building robust charging hardware and being a longterm partner. Chagrin stations are complex and requires a lot of interoperability with other systems such as software, vehicles, wires, etc.

While remote monitoring provides many benefits, there are several challenges:

  • Connectivity Issues: Weak or unstable network connections can cause issues in real-time data transmission, especially in areas with poor signal strength or heavy interference.
  • Device Configuration Changes: As previously mentioned, changing a charger’s connectivity method can disrupt its OCPP integration, requiring a full recommissioning process.
  • Data Privacy and Cybersecurity: With remote monitoring, it’s crucial to ensure that chargers are secure from cyber threats. Siemens recommends using updated security measures such as firewalls and encrypted communication protocols.

Conclusion

Siemens provides robust solution that can be monitores through the OCPP software across a wide range of environments. With software integrations, users can ensure their charging infrastructure operates efficiently, reduce downtime, and gain valuable insights into energy usage and device performance. By leveraging technologies like OCPP and Siemens Device Management, businesses can remotely manage their chargers, ensuring they stay up to date with the latest software and firmware.
