Abstract

The disclosure relates to a computer-implemented method for generating software for a battery management unit. Said method comprises at least the step of: generating a central battery configuration. In addition, the disclosure relates to a battery that can be operated using the software, and to a motor vehicle which comprises such a battery.

Claims

a sensor drive system; and

at least one battery cell sensor connected to at least one battery cell in the plurality of battery cells; and

a central management unit operatively connected to the plurality of cell monitoring units, the central management unit comprising;

a control unit operatively connected to the sensor drive system in each cell monitoring unit of the plurality of cell monitoring units, the control unit being configured to;

retrieve a first test case for the first cell monitoring unit in the plurality of cell monitoring units from a central test case catalog;

identify a first type of the sensor drive system in the first cell monitoring unit and a second type of the at least one battery cell sensor with reference to predetermined configuration data in the battery management system;

generate a first compiled executable for the first test case corresponding to the first type of the sensor drive system and the second type of the at least one battery cell sensor in the first cell monitoring unit; and

transmit the first executable to the first cell monitoring unit for execution by the sensor drive system in the first cell monitoring unit.

2. The battery management system of claim 1, the control unit in the central management unit being further configured to:

retrieve a second test case for a second cell monitoring unit in the plurality of cell monitoring units from the central test case catalog;
