The IBS system is used primarily for the start stop function which eliminates the burning of fuel while at complete stop, also reducing CO2 emissions. How does the IBS system help improve fuel efficiency? The IBS system is attached to the negative battery terminal and contains micro processors which measure and monitor voltage, current, charge and discharge as well as temperature of the battery. The newer models are equipped with IBS or Intelligent Battery Sensors. All of the advancement is ultimately pushed forward in the name of improving gas mileage.
