We are involved in system and detail design down to cabinet level, as well as installation planning and set to work.
The Battery Monitoring System (BMS) is a wireless system intended for measurements of voltage, acid level and acid temperature for all battery cells. The busbar voltage drop between two cells is also measured. The measurements are performed by Cell Probes fitted on each battery cell.
The Cell Probes are sending data (wirelessly) via a Probe Interface to the Interface Unit. There is one or two Probe Interface and one Interface Unit per battery compartment. The Interface Unit (IU) collects information from the Cell Probes (via the Probe Interface). Depending on customer requirements the IU can also include insulation monitoring and collection of external signals, e.g. for total battery voltage and current.
The IUs communicate with the operator system to be used. This operator system could be a Ships Control and Monitoring System (SCMS) or a dedicated Battery Monitoring Computer (BMC). It is also possible to connect a PC directly to the IU unit for service and maintenance of the system.
There are 4 main benefits of using our wireless BMS for Submarine battery. It has low maintenance, reduce cabling, reduced MTTR and simplified service/repair work.
