Battery and Current Sensors

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, power ability and aging of the battery.

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. The sensor is thus essential to the reliable operation of automotive start-stop systems. 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. 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.

Benefits & Features

  • Supports CO2 reduction measures, such as intelligent alternator control or stop/start function
