The intelligent battery sensor (IBS) from HELLA measures the battery parameters of voltage, current and temperature accurately and reliably, making it the key element for vehicle energy management. Information on the state of charge, state of health and state of function of the battery can be calculated based on measurements using advanced algorithms. Due to the modular approach, the IBS is suitable for batteries with DIN or JIS polarity, and for use in starter (standard or EFB), gel and AGM (fleece) batteries. Using intelligent interface management (LIN protocol), integration into a higher-level vehicle electrical system is not a problem. The IBS is attached directly to the negative terminal of the battery via the pole terminal. In addition to the terminal, the mechanical portion of the battery sensor consists of shunt and ground bolt components. The shunt is attached to the vehicle’s load path and is used as a measuring resistor to measure the current indirectly. On the ground bolt, the existing ground cable can be conveniently attached, for example, to the optionally available battery pole adapter. The electronics are located in a cast housing with a plug connector which functions as the interface to the energy management system.
The intelligent battery sensor (IBS) from HELLA provides important information about the current energy status of the vehicle, allowing you to plan your energy supply efficiently. Weak batteries are one of the main causes of vehicle breakdown, which may constitute a substantial cost factor in the construction machinery sector due to loss of work time. It is even more important to use energy from the vehicle electrical system battery sparingly. However, this can only be achieved if the state of charge, state of health and changes to the battery are known at all times – a task that the IBS carries out precisely.
By using the intelligent battery sensor and through integration into the vehicle electrical system, the energy management system can react quickly in the event of a critical battery condition and influence both consumption behavior and the function of the alternator. This significantly reduces the risk of a vehicle breakdown caused by a dead battery. In addition, the IBS supports functions such as stop/start and the intelligent alternator control, which are used to reduce CO2 emissions and protect the environment.
The sensor's compact and efficient design allows maximum flexibility for integration into various vehicle environments and minimizes the number of variants.
