Intelligent Battery Sensors (IBS) 24 V

Electrics and ElectronicsEnergy management

Energy management at the highest level: The intelligent battery sensors (IBS) from HELLA do just that. They measure battery variables such as current, voltage, and temperature. The measured values provide information on the state of charge (SOC), aging (SOH), as well as the expected starting capability (SOF) of the battery. The intelligent battery sensors therefore permanently monitor key parameters and provide early warning of a weak or defective battery.

 

The HELLA IBS are designed to fit perfectly around the negative terminal of the battery. The mounting control is done via the pole terminal. As a measuring resistor for indirect current measurement, the shunt component of the battery sensors is attached to the vehicle’s load path, while the existing ground cable can simply be attached to the earthing bolt. The IBS electronics are located in a cast housing with a plug connector. Communication with the higher-level control unit related to the battery’s energy status is done via the LIN protocol.

Product Advantages

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