1. A method for monitoring a plurality of battery modules of a battery with at least two data processing devices, comprising:
- measuring variables from each battery module of the plurality of battery modules with a plurality of sensors, each sensor of the plurality of sensors being connected to the at least two data processing devices via a communication link;
evaluating the measured variables with the each of the at least two data processing devices, the evaluating being performed by each of the at least two data processing devices redundantly and simultaneously;
monitoring signals interchanged via the communication link for errors using the at least two data processing devices, the monitoring being performed by each of the at least two data processing devices redundantly and simultaneously; and
monitoring one of the at least two data processing devices with another of the at least two data processing devices.

Abstract
The present disclosure relates to a method and an arrangement for monitoring at least one battery, to a battery having such an arrangement, and to a motor vehicle having a corresponding battery that is used for safely monitoring the battery condition with a reduced amount of hardware. The at least one battery is monitored by analyzing measured variables of the at least one battery using at least one data processing device. The signals exchanged between the at least one battery and the at least one data processing device via a communication connection are monitored at least once.
