Smart Battery Sensor (SBS)

Electricfil The Smart Battery Sensor (SBS) continuously measures the battery current, voltage and temperature using noncontact technologies including a Hall-effect current sensor.

This non-intrusive current sensing solution offers many advantages over shunt type current measurements, mainly related to the fact that no component is inserted in the battery circuit.

The SBS uses patented algorithms developed by Electricfil and tested by a major battery manufacturer to calculate the state-of-health (SOH), state-of-charge (SOC) and stateof-function (SOF) information required by the vehicle's energy management system from the voltage, current and temperature measurements.
