- each adapter requires its own hardware circuit and in addition each unit, which is connected to the interfaces of the adapter, includes its own evaluation circuit.
- the electromechanical adapter comprises at least one control unit, wherein the adapter at least a first interface for communication with at least one battery-side monitoring unit, a second interface to
- Connection of at least one sensor and / or actuator comprises, wherein the control unit converts signals between the first and the second interface.
- the electromechanical adapter comprises at least one further component for converting the signals, for example a CAN bus controller and / or a programmable component.

- the controller uses stored substitute values for the signals, for example, the stored maximum threshold is used when a signal exceeds this maximum threshold.
- the controller adjusts a sampling frequency for detecting the signals, for example, the sampling frequency is increased when the compared signals differ within a tolerance range to ensure early detection of a normal state. If the compared signals no longer differ, the sampling frequency is reduced again.
- control unit activates an actuator if the signals deviate from one another during the plausibility check.
- control unit emits an alarm signal so that further monitoring units can take measures for error handling, for example by opening contactors disconnecting a battery from an electric drive of a vehicle.
