Intelligent Battery Sensor

Intelligent Battery Sensor

The shunt-type IBS continuously analyzes the status of conventional 12-Volt lead acid batteries and provides information on such key parameters as the state-of-charge, state-of-function (power ability) and state-of-health (aging) of the battery. Dedicated algorithms developed by Continental can be offered as well as a pure high precision measurement interface.  The sensor is thus essential to reliable operation of automotive start-stop systems. The IBS informs a higher level control unit such as the engine control unit or the body control unit whether there is sufficient energy left in the battery, thus ensuring that the engine can be automatically shut off and cranked again. It also supports that electrical devices such as the radio or the ventilation fan continue to operate during the stop phase.  In hybrid vehicles the IBS sensors' accuracy and specific algorithms are necessary for inertial resistance (Rint) measurements.  The IBS is mounted directly onto the battery and fits exactly into the niche around the negative terminal. This means that it can be deployed with any standard battery.  In addition to being able to monitor the battery, the IBS also helps to detect defective electronic components in the car, thanks to its monitoring of the key-off current. The sensor enhances the automobile’s diagnostic ability and can thus warn of possible breakdowns that may not even be caused by the battery.  Moreover, the IBS helps to extend battery life by 10 to 20 percent via an improved charging strategy.
