WPC-BSI 500 Battery Status Interface

One of the most important indicators for a safe and effective operating of an energy system with batteries is their state of charge. The BSI offers, for Whisper Power Centre, a highly precise measuring and an extremely efficient algorithm that calculates the state of charge in the most accurate way.

The WPC-PSCP and WPC-RCC provides the display, the data logging, the graphical display of the state of charge history and the settings. Values of the BSI can be used in the programming of the WPC Series.
Values can be displayed like for instance:

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