Abstract

Electromechanical adapter having at least one controller, wherein the adapter comprises at least a first interface for communication with at least one monitoring unit at the battery, a second interface for communication with a monitoring unit that is superordinate to the monitoring unit at the battery, and a third interface for the connection of at least one sensor and/or actuator, wherein the controller converts signals between the first and second interfaces.

First claim

The invention claimed is:

1. An electromechanical adapter comprising:
at least one controller,
at least one first interface for communication with at least one battery-side monitoring unit,
a second interface for communication with a monitoring unit that is connected to a central control unit, and
a third interface for interfacing at least one selected from the group consisting of a sensor and an actuator,
wherein the controller converts signals between the first interface and the second interface based on a sensor signal from the third interface, and
wherein the first interface and second interface have different communication protocols.

2. The electromechanical adapter as claimed in claim 1 , further comprising at least one component for converting the signals.

3. The electromechanical adapter as claimed in claim 2 , wherein the at least one component comprises a CAN-bus controller, a programmable component, or both.

4. The electromechanical adapter as claimed in claim 1 , wherein the first interface is a serial interface.

5. The electromechanical adapter as claimed in claim 1 , wherein the first interface, the second interface and/or the third interface comprise plug-in connections.

6. A method for operating an electromechanical adapter having at least one controller, the method comprising:
converting signals between a first interface and a second interface using at least one selected from a group consisting of the controller and a component of the electromechanical adapter by adapting at least one selected from a group consisting of a signal waveform and a signal level,
wherein the first interface and the second interface have different communication protocols, and
wherein the signals are converted based on a sensor signal from a third interface of the electromechanical adapter.

7. The method as claimed in claim 6 , wherein the controller performs a plausibility check on the signals.

8. The method as claimed in claim 7 , wherein the controller performs the plausibility check by a signal-comparison of signals that are acquired by different measurement methods and/or different sensors, and/or compares signals with defined threshold values for extreme values and/or average values.

9. The method as claimed in claim 8 , wherein the controller blocks signals that lie outside the defined threshold values, uses stored substitute values for the signals, adapts a sampling frequency for the signal acquisition and/or actuates an actuator if the compared signals differ from one another.

10. The method as claimed in claim 6 , wherein the controller uses the signal waveform and/or the signal level to detect errors.

11. The method as claimed in claim 6 , wherein the controller outputs an alarm signal to the third interface on the basis of the plausibility check, errors or both.
