Quick Overview

Battery monitoring system is used to permanently monitor fixed installed batteries. The BMS monitors the attached battery while it records constantly the battery’s parameters to the plugged USB-stick. When needed, the stick can be removed any time to evaluate the current and past battery state.

All cell voltages as well as the current, the ripple current and the ripple voltage of the whole battery are available on the USB-stick if wanted. Furthermore also the battery room temperature and its hydrogen concentration are also written to the USB-stick.

On the high resolution display all measured parameters can directly be displayed without the use of a PC or a tablet. Additionally the instrument can be directly connected via USB to a PC or the Megger Torkel instrument.

Since the instrument is equipped with a standard MODBUS RTU interface, the data can easily be made available on your local PLC or PC without a large software overhead. Like this, the battery is remotely monitored and you have the data available at all times.

In case, you need to monitor more than 60 cells, the instrument can directly be cascaded with its second RS485 interface in order to allow more cells.

Furthermore, the instrument has 3 potential free relay contacts. Multiple parameters can be pro- grammed to these relays to have a simple inter- face. Like this the instrument is connected to a PLC without the use of MODBUS.

For discharge and impedance tests, the instru- ment can be directly connected to the Megger Torkel instrument.
