Monitoring ABB chargers efficiently is critical for ensuring their reliability, maintaining uptime, and optimizing energy usage. This comprehensive guide explores ABB chargers, their connectivity options, remote monitoring capabilities, and the challenges of integrating third-party software.
Types of ABB Chargers
ABB chargers are designed to suit a wide range of applications, including:
DC Fast Chargers
ABB DC fast chargers are ideal for rapid charging of electric vehicles (EVs) in high-demand environments. Models like the Terra series deliver power levels of up to 350 kW, making them popular in bus and truck depots worldwide, including in the U.S., Europe, Africa, and Latin America.
AC Chargers
ABB AC chargers are perfect for residential or workplace charging, offering power levels up to 22 kW (220V) or 7 kW (120V). They are also used in overnight depots for last-mile delivery vehicles.
Known for their premium pricing and high reliability, ABB chargers are a solid choice for charging depot owners. However, challenges may arise when attempting to integrate them with third-party monitoring software for remote monitoring. These challenges are detailed later in the article.
How to Connect ABB Chargers to the Internet
Internet connectivity is a prerequisite for remote monitoring of ABB chargers. Here are the most common methods:
Ethernet Connection
Most ABB 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 and robust connectivity solution. A centralized router with wired internet access and backup SIM cards can further enhance reliability.
Wi-Fi Connectivity
Some ABB chargers offer Wi-Fi connectivity, which can be configured directly on the charger or using ABB’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.
Integrated Cellular Modems
For remote locations without reliable wired or Wi-Fi access, ABB chargers can utilize built-in cellular modems. While these provide independent connectivity, they require multiple SIM cards and may have limited signal strength.
Data Security for ABB Chargers
When connecting ABB 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 ABB Chargers with Remote Monitoring Software
After establishing internet connectivity on-site, the next step is to connect your ABB charger to your monitoring platform using the OCPP protocol. As one of the earliest adopters of OCPP, ABB chargers are compatible with a wide range of third-party software. However, it is recommended to avoid relying on ABB's native monitoring software, as it is outdated and lacks the advanced functionalities required for large charging depots or operations that demand high uptime.
Connecting ABB DC Chargers to Monitoring Software
- Verify the ABB charger supports the required OCPP version (e.g., OCPP 1.6 or OCPP 2.0.1).
- Obtain the backend URL and credentials for your monitoring platform.
- Update the OCPP settings through ABB support or directly via the charger’s interface.
- Reboot the charger and confirm the connection to the monitoring software.
Connecting ABB AC Chargers to Monitoring Software
- Pair the charger with the ABB TerraConfig Mobile App (name may vary by region).
- Enable “External Access” in the OCPP server settings.
- Enter the WebSocket URL provided by your software.
- Reboot the charger and verify the connection.

Data Insights from ABB Chargers
ABB chargers provide extensive data for remote monitoring and optimization. Key metrics include:
- Charging Session Data: Start/stop times, energy dispensed (kWh), session duration, and user details.
- Charger Status: Current status (idle, charging, fault), error codes, and firmware version.
- Energy Metrics: Real-time power usage, voltage/current levels, and energy trends.
- Environmental Data: Ambient temperature and humidity (if supported).
This data is crucial for leveraging smart charging functionalities, managing grid connections, and optimizing energy costs. When utilizing smart charging functionalities to manage power and energy, ABB chargers will report power output in response to your commands. This capability is essential for scenarios such as oversubscribing grid connections or adapting to variable energy pricing, ensuring efficient energy management and cost optimization.
Challenges in Remote Monitoring of ABB Chargers
While ABB chargers are robust, users may encounter obstacles when integrating third-party remote monitoring software:
Limited Support for Third-Party Software
Using non-ABB software to manage ABB chargers is a common industry practice and often the preferred choice due to the advanced features, enterprise-level functionalities, and higher uptime these platforms provide. However, ABB does not always fully support this approach, and customers may face challenges when connecting chargers or performing firmware updates. Support responses can be slow, with some issues taking weeks to resolve. In certain cases, firmware updates may not be possible because the chargers do not fully comply with the OCPP protocol, adding further complications.
Data Inconsistencies
Similarly, when integrating ABB chargers with third-party OCPP software, accessing the full range of OCPP data can be challenging. Default settings often omit critical metering and session information, requiring intricate adjustments within the ABB configuration. Resolving these issues may involve complex navigation and depend on ABB support, which can take several days to provide assistance.
Smart Charging Limitations
When integrating an energy management system, it is crucial that the charger consistently follows the commands issued by the energy management software. However, in many cases, default settings on ABB chargers disable this functionality. Resolving the issue often requires configuration changes, which can take several days to address due to delays in obtaining support from ABB.
Conclusion
Monitoring ABB chargers effectively with remote monitoring software is essential for optimizing performance and ensuring reliability. By understanding the types of chargers, internet connectivity options, and data insights available, you can set up a robust monitoring system tailored to your needs. While ABB chargers deliver high-quality performance, integrating them with third-party software may present challenges that require persistence and technical expertise. Following this guide can help you overcome these obstacles and maximize the value of your ABB chargers for remote monitoring.
