Intelligent 12 V battery sensor (IBS)
Intelligent 12 V battery sensor (IBS)

Intelligent Battery Sensor (IBS)

  • Accurate measurement of battery voltage, current and temperature parameters
  • Determination of the battery state of charge (SOC), state of health (SOH) and state of function (SOF) condition parameters
  • Simple electrical and mechanical integration

 Customer Benefits

The intelligent battery sensor (IBS) informs you about the current energy status, allowing you to plan your energy supply.

In order to carefully conserve the energy of the vehicle battery, it is necessary to know the state of charge, ageing and any changes to the battery, as weak batteries are the main cause of vehicle breakdown in more than 50% of cases according to a study by the ADAC, the German automobile association.
