How to Monitor Power Electronics Chargers Effectively

Power Electronics offers a diverse range of electric vehicle (EV) charging solutions, designed for commercial, industrial, and residential applications. The chargers are known for their scalability, high power density, and advanced features like dynamic power distribution, and robust connectivity. Integrating these chargers with remote monitoring software, like Ampcontrol, optimizes performance and maintenance, ensuring reliable and efficient charging operations.

Types of Power Electronics Chargers

Power Electronics provides both AC and DC chargers, offering flexible solutions for various use cases. The AC chargers include the NB Wall and NB City, suitable for urban and residential environments. DC chargers encompass high-power options such as the NB Station, NB Standalone, NBi 180, NBi 360, MCS, and NBw30 solutions, designed for fast and ultra-fast charging, including megawatt-level charging for heavy-duty vehicles.

Key features of Power Electronics chargers include:

• Smart Power Balance for optimized energy use
• Modular and scalable design for future-proofing
• High power density with dynamic power distribution
• Multiple connectivity options (Ethernet, Wi-Fi, Cellular)
• Compliance with international standards (IEC, UL, OCPP)

Geographically, Power Electronics chargers are widely deployed across Europe, the United States, and other global markets. These chargers are especially popular in fleet management, public charging infrastructure, and commercial applications.

How to Connect Power Electronics Chargers to the Internet

Power Electronics chargers support various connectivity options to facilitate integration with monitoring software:

• Ethernet: Most chargers come with Ethernet (10/100) support, allowing stable and high-speed wired connections to local networks.
• Wi-Fi: Many models offer Wi-Fi connectivity as an alternative to Ethernet, providing flexibility in installation without the need for physical cables.
• Cellular (4G/3G/GSM): Cellular connectivity ensures remote monitoring even in areas lacking wired internet. Ideal for mobile and remote setups.

Integrating Power Electronics Chargers with Remote Monitoring Software

Configuration of Power Electronics chargers can be done both onsite and remotely. The software supports Open Charge Point Protocol (OCPP) versions 1.6J and 2.0.1, ensuring compatibility with various charging management systems. Additionally, the platform provides error management and remote diagnostics, minimizing downtime.‍

1. Access Charger Configuration Interface

• Use the local interface (e.g., touchscreen or web portal).
• Alternatively, connect through Power Electronics’ proprietary configuration tool or app (if available).
• Login credentials are usually admin-protected; refer to the installer manual for default credentials.

2. Network Setup

• Ensure the charger is connected to the internet (via Ethernet, Wi-Fi, or 4G).
• Assign IP, Gateway, and DNS manually or via DHCP.

3. Configure the OCPP Backend

• Navigate to the OCPP settings section in the configuration menu.
• Enter the OCPP server URL provided by your backend provider (e.g., wss://connect.ampcontrol.io/... for secure WebSocket).
• Set the OCPP version (usually 1.6 or 2.0.1 depending on compatibility).
• Define the Charge Point ID (this must match the ID registered on the backend system).
• If available, enable OCPP over WebSockets (WS/WSS) and ensure correct port (default is 80 for WS, 443 for WSS).

4. Save and Reboot

• Save settings.
• Reboot the charger if required to initiate connection to the backend.

5. Backend Verification

• Check the backend system to confirm that the charger has connected and is sending heartbeat/status updates.

Data Insights from Power Electronics Chargers

Power Electronics chargers provide comprehensive data reporting, including charging status, power output, energy consumption, and fault diagnostics. Key data points include:

• Real-time power usage and efficiency metrics
• Error messages (e.g., overcurrent, communication failures, overheating)
• Historical data for performance analysis

Advanced data accuracy is achieved through optional DC meters, allowing precise monitoring of energy consumption and operational health.

Challenges in Remote Monitoring of Power Electronics Chargers

One potential challenge in remote monitoring is ensuring connectivity stability, especially in areas with poor cellular coverage. Regular updates and configuration management are necessary to maintain consistent data synchronization between chargers and the monitoring platform. Another challenge may arise when managing mixed fleets with both AC and DC chargers, requiring tailored integration strategies.
