ABB Terra AC

This DDF enables the integration of an ABB Terra AC wallbox into the OS E-Mobility System via Modbus TCP.

The connection enables monitoring and control of the wallbox and can be used in particular for dynamic load management, energy monitoring, and PV surplus charging.

The available data can be used, for example, to monitor the current charging power and the energy consumption of a charging session and to make this information available for E-Mobility and building automation.

Requirements

The following requirements must be met to use this DDF:

• a compatible ABB Terra AC wallbox
• a functioning Modbus TCP connection between the wallbox and the OS E-Mobility System
• the network address of the wallbox
• the wallbox settings required for Modbus TCP communication

The ABB Terra AC must be configured accordingly for communication via Modbus TCP and must be reachable on the network.

Usage

After successful setup, the wallbox can be integrated into the OS E-Mobility System and used for various applications.

• Charging monitoring: The current charging power and other available status information can be monitored.
• Energy monitoring: The energy consumption of the current charging session can be recorded and evaluated.
• Dynamic load management: The wallbox can be integrated into a higher-level load management system to distribute the available electrical power efficiently.
• PV surplus charging: Surplus energy from a photovoltaic system can be used to charge the vehicle.

The specific control and automation are defined via the OS E-Mobility System or the higher-level building automation system.

Important Notes

RFID management is handled directly via the wallbox's TerraConfig App and is not managed through the OS E-Mobility System.

The ABB Terra AC is operated as a fixed 1-phase or 3-phase installation. Dynamic switching between 1-phase and 3-phase operation is not supported by this DDF.

Depending on the version, the wallbox is designed for a charging power of up to 11 kW (3-phase, 16 A) or 22 kW (3-phase, 32 A).

The actual available charging power depends on the installation, the wallbox configuration, and the existing electrical conditions.
