Intelligent Battery Sensor

Intelligent Battery Sensor (IBS)


  • Accurate measurement of voltage, current, and temperature battery parameters
  • Determination of the state of charge (SOC), state of health (SOH), and state of function (SOF) battery condition parameters
  • For use in starter, gel and AGM batteries to monitor in-vehicle starter or consumer batteries.
  • Direct integration into the vehicle electric system via standardized LIN protocol
  • Key element of energy management

 Customer Benefits

  • Information indicator on energy balance allows you to plan your energy supply
  • Information on the battery condition reduces the likelihood of a vehicle breakdown
  • Dead batteries are the main cause of breakdowns. The battery sensor helps prevent this
