Battery Status Processor BSP

One of the most important information for a safe and effective operating of an energy system with batteries is their state of charge. The BSP offers, for Xtender, VarioTrack and VarioString systems, a highly precise measuring and an extremely efficient algorithm that calculates the state of charge in the most accurate way.

The remote control RCC-02/03 provides the display, the data logging, the graphical display of the state of charge history and the settings. Values of the BSP can be used in the programming of the Xtender, VarioTrack and VarioString system. Besides, 17 different values can be displayed like for instance:

  • State of charge
  • Voltage
  • Current
  • Time to go
  • Throughput energy
  • Battery temperature

The BSP is offering a voltage measuring for 12, 24 and 48 V batteries and a current measuring by resistive shunt.

Two models of BSP are available:

BSP 500 (with a shunt of 500 A)
BSP 1200 (with a shunt of 1200 A)

Dimension H x L x l: 110.5 x 75 x 26 mm.
Cable length for the battery connection: 2 m
Supplied with a 5 m communication cable and a shunt of 500A (for the BSP 500) or of 1200A (for the BSP 1200)

Communication module Xcom-232i

The communication module Xcom-232i, equipped with a serial port RS-232, enables to be informed of the state of a system consisting of one or several Xtenders, VarioTracks or VarioStrings.

It is then possible to read all data that can be displayed on the remote control basic screen and also to modify the configuration parameters. An Xtender, VarioTrack or VarioString system can therefore be connected to various SCADA control and supervision devices (PC, programmable logic controller, and microcontroller).

From a more technical point of view, the electrical interface RS-232 allows for instance the data transmission with GSM modems, RS-232 bridges to TCP/IP or also with long distance converters RS-422. Besides, in order to secure a total electrical separation between the Xtender, VarioTrack or VarioString system and the control and supervision device, the port is protected by means of a galvanic isolation.

The module Xcom-232i is also having a function of data recording and analysing (Data logger function).

If you have no serial port RS-232, there is a version with CAN bus.

Dimension H x L x l: 110.5 x 75 x 26 mm.
Supplied with a 2 m communication cable.

Communication sets by internet with Xcom-LAN / Xcom-GSM

Xtender, VarioTrack and VarioString systems can now be constantly controlled from any remote terminal, computer, tablet or smartphone. The communication sets Xcom-GSM and Xcom-LAN allow connecting to sites with GSM mobile coverage or with internet-connection over a local network.

Studer Innotec provides this «plug-and-play» solution using a secure server and a simple and user-friendly interface.

The interface allows for remote interaction with the installation exactly as if on-site with the remote control RCC-02/-03, including: access to all parameters, real-time display of measured data of all devices included in the system and access to the last 30 days of log files.

Furthermore this solution makes it possible to consult the system’s event log at any time. It also allow users to configure alarm messages to be sent to one or more persons by e-mail or SMS. Any loss of internet connection can be indicated.

Xcom-LAN or Xcom-GSM?
Studer Innotec offers two different communication sets for providing access to the installation via internet. The available means of communication at the location of the installation will determine which set to choose.

If the installation has access to internet through a local area network (LAN), choose the Xcom-LAN set. If there is no available connection to the internet but access to a GPRS or 3G mobile network*, choose the Xcom-GSM set.

* the compatibility should always be verified with the mobile phone network operator

Communication set Xcom-LAN
The set includes one Xcom-232i, one Ethernet port and all necessary accessories

Communication set Xcom-GSM
The set includes one Xcom-232i, one cellular modem and all necessary accessories. The SIM card is not provided.

Multi-protocol communication module Xcom-CAN

This tool enables the communication between BMS, Lithium Battery Management Systems, and products of the Xtender / VarioTrack / VarioString family. The list of batteries (manufacturers) compatible is available on request at Studer-Innotec. The Xcom-CAN makes it also possible for any device with a CAN bus (PC, PLC and microcontroller) to interact with all products of the Xtender / Vario family via a proprietary protocol. Like having the system controlled by a supervisor (SCADA) while giving the third system an access to all data (configuration parameters and datalog).

Communication Cable for multi-unit Systems

This communication cable enables Xtenders, VarioTrack and the VarioString to be connected together in order to build multi-unit systems.

Several Xtenders, VarioTracks and VarioStrings can therefore be used in the same installation to make either a 3ph system, to increase the power of one phase, or both.

Up to 9 Xtenders,15 VarioTracks and 15 VarioStrings can then be combined, offering a power max. of 72 kVA and 75kWp for the VarioTracks and 105kWp for the VarioStrings.

BTS-01 Battery Temperature Sensor

This sensor enables to accurately adapt the charge thresholds to the battery temperature.

Application

Solar BTS with inverter/charger Compact

Solar power for BTS with inverter/charger Compact series. A hybrid solution offers to strongly reduce the diesel consumption and to significantly raise the generator efficiency (lowering the operational costs, increasing the lifetime).
The solar energy in excess will be used through the inverter-charger for other loads (AC). Moreover a supervision of the battery is integrated, disconnecting the inverter output if the battery voltage is too low, thus ensuring a longer battery life.

Quality AC voltage for all electrical appliances with inverter/charger Xtender

The inverter supplies, exclusively from a battery, any kind of appliance using AC voltage, without exception. It does converts the battery’s DC voltage into AC voltage at a higher quality than what is available from the public grid.

Backup applications-UPS with solar backup and solar priority with inverter/charger Compact

When it is forbidden or there is no incentive to inject energy into the public grid, the Compact, with optional built-in solar charge controller will minimize the grid consumption in favour of the locally produced energy. They will also guarantee an energy supply in case of grid-failure. This solution is easy to set-up using Studer products. A simple “plug-and-play” solution.

Village electrification

Supplying energy to professional applications like hotels, health centres, hospitals, schools, etc. requires reliable, modular and powerful stand-alone systems. Building a public micro-grid implies the same requirements. The product family Xtender / VarioTrack / VarioString, with its flexibility, offers the right building blocks to construct a suitable micro-grid. Combining the products of this family enables the design of systems from a few kVA to 72kVA, while covering a large range of applications. The various communication means available (GSM, Web, SMS) offer full control of the micro-grids.

The well-known flexibility of the Xtender, heart of the micro-grid, allows to design tailor-made systems. With integrated frequency control, the Xtender controls a grid-inverter when present in the micro-grid, allowing for either AC or DC coupling of solar PV.

Priority to renewable energy without grid-injection
