Home » Cinergia B2C series bidirectional battery charger
The Cinergia B2C series bidirectional battery chargers are part of a DC product line. The B2C units can be used for both charging and discharging of a battery. Therefore, this model works both as a DC power supply and DC load. When discharged, the energy is not converted into heat (as most loads do) but is returned to the Electric Grid.
This product line of bi-directional battery chargers is suitable for so-called 2Q and 4Q applications: for use in both bipolar current and bipolar voltage applications. Charging a battery is controlled via an IUoU algorithm. A discharge can occur at a constant current, a constant power or via a fixed resistance value. Loading and unloading profiles are easy to program via an Excel file.
The B2C is available from 9 kW to 160 kW and contains three individual inlet channels. Each channel can be used independently, allowing programming of different voltage, current and power values. Parallel switching of the three channels offers the user one in- and output with power in its entirety. Depending on the model, a current of 15A to 185A per channel is available within the voltage range from 20 to 750 Vdc (optional 800V). In parallel mode, this equates to 45A to 555A. When using the B2C battery chargers it is recommended to use the optional isolation transformer to achieve galvanic isolation.
The Cinergia B2C series bidirectional battery chargers models have extensive measurement functions and can be operated manually as well as via the standard LAN Ethernet with Modbus/TCP protocol. Optionally, RS485, RS232 or CANbus communication is also possible. The specifically developed Graphical user interface is standard available.
Cinergia B2C series battery chargers consist of the following models:

"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."

“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.”
