G5.BT Battery Test Solution

The G5.BT series is bidirectional regenerative and it was developed specifically for testing energy storage devices and is suitable for use in laboratories and on test benches. The modular and finely graded G5.BT series is characterized by highly dynamic response times and a wide current-voltage range with an auto-ranging factor 3. The G5.BT series has outstanding accuracy, an additional high-resolution current measurement

range, and a fast current rise time in the 100 μs range. Ripple modulation, an integrated safety relay for PL c according to EN ISO 13849 and a powerful CAN multi-protocol interface (1 kHz, 16 bit) as well as functions to avoid reverse-polarity problems, current surges, and unwanted deep discharges make the G5.BT series the ideal, versatile battery module and battery pack tester.

Battery Module / Pack-Testing Features

The G5.BT series has an exceptional electrical performance that offers several advantages for battery testing applications:

  • Voltage accuracy of <0.01…0.02% FS
  • Current accuracy in the range 0.03…0.09% FS depending on model
  • Additional high-resolution current measurement range from -10 to 10% FS with an accuracy <0.005% FS
  • Current rise time in the 50…200 μs range
  • Parameterizable to avoid overshoot
  • Current ripple modulation up to 10 kHz

In addition, the G5.BT provides important features for user safety, power supply, and battery protection. It avoids:

  • Reverse-polarity problems
  • Arcing and high inrush current when connecting the battery to the DC terminals even at unmatched voltage levels
  • Deep battery discharge at voltage off state (DC port impedance >10 MΩ)
Parameterization example of a 36 kW, 1000 V, 108 A device: Set-value step current -97…97 A@333VDC in <50 μs with overshoot (top), in <200 μs w/o overshoot (bottom). This dynamic behavior is characteristic for all G5 devices.

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 preprogrammed 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.BT series also offers the possibility to store, edit, and recall any device configuration on board the power supply.

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.

Bidirectional DC power supply G5 modular system – REGATRON scalable programmable power supplies
Modular concept for easy power and voltage increase by parallel, series, and mixed operation. The parallel configuration allows even the operation of devices with different output power, e.g., 18, 36, and 54 kW modules, in one system.

Characteristics and Features in the Basic Scope of the G5.BT Series

CV constant voltage
CC constant current
CP constant power
CR constant resistance
Ri internal resistance simulation in CV
Gi internal conductance simulation in CC

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.

.NET programming, e.g., by LabView, Python, Matlab

Interface via the optional HMI or RCU

The CAN multi-protocol (CANmp) interface has a 1 kHz data rate, a 16-bit resolution, and is adaptable to any proprietary CAN bus. In addition, it supports dbc file handling.

Integrated safety relay (ISR) for increased emergency stop reliability supporting performance level PL c / PL e according to EN ISO 13849.

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.

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
