The Cinergia Regenerative Battery Emulator is part of a line of two-way regenerative DC inverters.

Features

The B2C+ Series Regenerative Battery Emulators are four quadrant DC power supplies that are designed to behave like real battery packs. The B2C+ with battery emulation functionality is equipped with a mathematical model to emulate the voltage behaviour of a real battery. The output voltage changes as a function of the SOC and the current. By configuring the supplied parameters, the voltage profile can be adapted to the different technologies: LiIon, NiMH, NiCd, Pb, Flux and so on.

Three regenerative four-quadrant DC power supplies / loads are available per cabinet, which can be used independently or in parallel. The output voltage ranges from 20 V to 750 V (optional  800 V). Voltages up to 1500 V can be achieved by connecting two units in series. The power is between 7.5 kW and 160 kW (200 kVA) in a single battery emulator unit. By means of parallel connection, larger capacities such as 1.2 MVA can be emulated via one master with multiple slave units.

This regenerative battery emulator works as a DC power supply as well as a DC electronic load. Thanks to the bi-directional hardware, energy is fed back into the grid during discharging instead of being completely converted into heat, as is the case with most loads. This offers significant energy savings when testing the charging and discharging cycles of the charger or inverter. The input and output current on the mains side is sinusoidal with a PF higher than 0.98 and a THDi < 3%.

Battery testing and battery emulation require specialized control algorithms and configuration parameters.

For these applications, CINERGIA has incorporated advanced control algorithms, which are incorporated into the DSP in real time, such as: constant current/constant voltage profiles (IUoU) for the battery charge/discharge cycle as a battery model. For the PLUS product family, each of these functions is controlled via a dedicated screen in the user interface. The battery test panel is included in the standard B2C+ and is available as an option for the AC/DC versions of GE+ and EL+.

The new Plus family uses a controller board with a 300 kHz oversampling on the measured current and voltage. This increases the resolution and, together with the low-noise measurements, ensures even better dynamic behaviour (< 1 ms) and extensive functionality: The new board offers independent setpoints per channel, independently configurable virtual resistance per channel (sink/source), programmable flanks, 40% ripple reduction due to phase shift in parallel operation and advanced features for battery test applications (charge/discharge/cycle) also according to IUoU. The intuitive and effective Test Editor panel for automated testing does make programming of the unit easy.

With the user-selectable limits and alarms for current, voltage, overcurrent, overvoltage and overload your application and your equipment is protected.

The new controller board also enables the automation of test cycles by configuring the number of cycles and transition conditions: min/max voltage, min/max current, Ah, time. Parameters and profiles can easily be read in and out via a .csv file.

Also new are the analog inputs where you can use the B2C+ units as an amplifier for PHIL (Power Hardware in the Loop) applications.

Applications

The regenerative battery emulator is ideal for two quadrant and four quadrant applications: testing battery chargers, testing inverters for electromobility and renewable energy; testing power storage systems and vehicle to grid testing.

WHAT OUR CUSTOMERS SAY

ABB

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

University of Luxembourg

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
