Abstract
A battery monitoring device includes a sensor device, which is electrically connectable to an automobile battery and may be placed thereon, and which is arranged to detect an operating variable of the battery. The battery monitoring device further includes a detection circuit, which is connected via a cable connection to the sensor device; and a data processing circuit, which is connected via a potential isolation circuit to the detection circuit. The potential isolation circuit provides isolation of the potential level of the detection circuit from a potential level of the data processing circuit for direct components.
