Abstract
A method for monitoring a first battery in a device, in particular in a motor vehicle, a first magnetometer measuring a magnetic flux density in the battery and/or adjacent to the battery, a second magnetometer measuring a magnetic flux density remotely from the first battery in the device, and in a period, in which no power supply or power withdrawal is provided to or from the first battery, a measurement of the first and the second magnetometer being carried out, and an evaluation unit, for the case in which the magnetic flux density measured by the first magnetometer exceeds a background magnetic flux density measured with the aid of the second magnetometer beyond a predetermined amount, determining and outputting an error status of the first battery.
