G5.BAS Series
G5.BAS Battery Simulation / Emulation Solution
The G5.BAS series is bidirectional regenerative. It was developed specifically for the simulation of energy storage devices and batteries and is suitable for use in laboratories and on test benches. The modular and finely graded G5.BAS series is characterized by highly dynamic response times and a wide current-voltage range with an auto-ranging factor three.
The power supplies are equipped with the powerful application software BatSim and reproduce the electro-chemical and electrical properties of different battery types in charge and discharge mode realistically and in real-time. This is done based on battery models that can be configured easily and conveniently.

Battery Simulation Features
The G5.BAS series realistically and dynamically simulate both the electrochemical and electrical properties of a battery type in charge and discharge mode.
Other features include high data resolution and options for meeting high safety standards for operators. The real-time computing process of the application software BatSim perfectly matches the internal timing of the DC power supply. Therefore, an optimum computing rate is achieved leading to very short response times even in cases of steep changes in charge/discharge currents. Each battery type reacts in a specific manner to charge and discharge currents in terms of state of charge, cell voltage, ohmic and parametric losses, and polarization effects. These dependencies are considered by specific mathematical models used in the REGATRON BatSim software / firmware. The operator can fine-tune the model with several well-defined parameters to adjust the simulation to a user’s requirement.
Features such as adjustable controller settings and the integrated powerful 8-channel digital scope assist the user to quickly and easily achieve optimal system behavior for a special application requirement.
Simplified and safe operation can be provided by pre-programmed overvoltage protection and digital fuses with immediate and I2t triggering. Different protection levels for different DUTs can be either programmed by the user’s automation test system via various interfaces or activated manually by digital input signals or even more conveniently wired to different switch positions.
The G5.BAS series also offers the possibility to store, edit, and recall any device configuration on board the power supply.
Models of the following battery types are available for configuration: Li-ion, lead-acid, NiMH, and NiCd.
Modular and Easily Scalable Systems
The output of an individual power supply is in the range from 0…9 kW to 0…5000+ kW, up to 3000 VDC. The advantageous modularity of REGATRON power supply solutions allows the system to be easily adapted to ever-changing test requirements. It is possible to reconfigure between parallel, series, and mixed operation. Moreover, the system can be expanded with additional power supply units or may be split into smaller units.
Whether for single devices or powerful multi-device systems, REGATRON also offers turn-key cabinet solutions or project-specific system integration according to customer specifications.
Therefore, the purchase of a REGATRON power supply is a solid investment for the future.

G5.Control over Ethernet or USB
G5.Control allows complete and easy control of the power supply unit or entire master slave system and also offers a whole range of service functions. In addition to basic control, configuration and update functions, G5.Control has a powerful integrated 8-channel digital scope . The high-resolution real-time display of numerous internal system signals allows the engineer to optimize the overall system in a targeted manner. Different application specific settings of parameters for single devices or master slave systems can be saved on the devices and either recalled by G5.Control, an API or CAN message or digital I/O signals. Firmware updates can be carried out quickly and easily for individual units as well as for master slave systems with a single command. When handling support cases concerning the application of the power supplies, the built-in diagnostic functions help to quickly identify the problem.
G5.BatSim - PC-Software for Battery Simulation
REGATRON’s user-friendly battery simulation software G5.BatSim is designed for simulation battery modules and packs with charge and discharge capabilities of a few kW up to the 5000+ kW range. In onjunction with the powerful real-time computing process of the G5 device, even steep changes in charge/discharge currents will be handled with the necessary dynamics and stability. Each battery type reacts in a specific manner to charge and discharge currents in terms of cell voltage, state of charge, ohmic and parametric losses, and polarization effects. These dependencies are considered by specific mathematical models used in the REGATRON G5.BatSim software / firmware. The operator can fine tune the model with several well-defined parameters to adjust the simulation to the user’s requirement. Long-term data recording and recall of battery values are available within the G5.BatSim application software.

API .NET over Ethernet or USB
.NET programming, e.g., by LabView, Python, Matlab
WebAPI (REST) over Ethernet or USB
Interface via the optional HMI or RCU
I/O Port
The I/O interface features analog and digital signals used for set and actual values or operating states. Integrated into the user’s control system it is possible to set dynamically changing limits, to use enable signals, or trigger in or outputs. The possibility to activate up to 4 user defined parameter sets using digital inputs means that the system can be adapted to different EUTs. For example, predefined digital fuses and voltage limits can be set.
Grid Connection
The wide band AC input accepts all common AC grid systems and has an active power factor correction.
- AC Grid 380…480 VAC ±10% at 50/60 Hz
- PF 0.99
- Efficiency 94…95%, depending on model
