"Admittance" is a composite measurement of all the battery's internal
resistances, including an apparent internal capacitance.
Each Power Agent BMS sensor generates a digitally synthesized
sinusoidal AC test signal (Itest) which is passes through the battery
terminals in order to measure the battery's admittance. A site controller
unit communicates with each o f the sensors to collect these admittance
measurements, along with battery voltage and post temperature.

Sensors: A sensor is attached to the posts of each monitored
battery. The sensors measure the battery's admittance (internal
resistance), voltage, and post temperature.
A Site Controller: The site controller communicates with each of
the sensors and collects the most recent measurement data. It
checks each measurement against locally stored alarm
thresholds and alerts the user's monitoring software is an
abnormality occurs. The site controller is fully Ethernet TCP/IP
compatible.

system that gives the user "freedom of choice" to select the
