Abstract

A method for generating diagnostic test files associated with a battery pack is provided. The method includes providing a diagnostic test data table having a plurality of records. A first record is associated with a first diagnostic test. The first record has a first parameter identifier and a first value. The method further includes generating a diagnostic test parameter configuration file having a data structure associated with the first diagnostic test by accessing the diagnostic test data table. The data structure has a first parameter variable that is set equal to the first value. The method further includes generating a diagnostic test software source code file based on the diagnostic test parameter configuration file utilizing a kernel translator program.

generating a diagnostic test parameter configuration file having a data structure associated with the first diagnostic test utilizing a computer that accesses the diagnostic test data table, the data structure having a first parameter variable that is set equal to the first value, and a second parameter variable that is set equal to the second value;

generating a diagnostic test software source code file based on the diagnostic test parameter configuration file utilizing a kernel translator program, the diagnostic test software source code file having an array with the first value and the second value that is associated with the first diagnostic test; and

generating a diagnostic test software source code response file based on the diagnostic test data table utilizing the computer, the diagnostic test software source code response file having the fault threshold value, and a first response flag configured to be set to a third value based on a result of the first diagnostic test.

2. The method of claim 1, wherein the diagnostic test software source code file and the diagnostic test software source code response file are configured to be compiled and operationally linked to a diagnostic kernel for performing the first diagnostic test.

3. The method of claim 2, wherein the first value corresponds to an increase scalar value, the increase scalar value indicating an amount to increase a diagnostic counter variable in the diagnostic kernel when the first diagnostic test indicates an undesired operational condition of the battery pack, the diagnostic counter variable being associated with the first diagnostic test.

4. The method of claim 3, wherein the second value corresponds to a decrease scalar value, the decrease scalar value indicating an amount to decrease a diagnostic counter variable in the diagnostic kernel when the first diagnostic test indicates a desired operational condition of the battery pack, the diagnostic counter variable being associated with the first diagnostic test.

5. The method of claim 1, wherein the diagnostic test software source code response file further includes a fault threshold hysteresis value to be utilized in the first diagnostic test.

6. The method of claim 1, wherein when the first response flag is set to the third value, the first response flag indicates that a hard fault condition of the battery pack has occurred and induces the computer to enter a predetermined operating mode.

7. The method of claim 1, wherein when the first response flag is set to the third value, the first response flag indicates that a hard fault condition of the battery pack has occurred and induces the computer to further send a first signal over a communication bus.

8. The method of claim 7, wherein the first signal corresponds to a signal utilized to light a warning lamp associated with the battery pack.

9. The method of claim 1, further comprising:

determining a hash code associated with the diagnostic test data table utilizing the computer; and

inserting the hash code into both the diagnostic test software source code file and the diagnostic test software source code response file, utilizing the computer.

10. The method of claim 1, further comprising:

comparing the hash code in the diagnostic test software source code file to the diagnostic test software source code response file utilizing the computer; and

compiling the diagnostic test software source code file and the diagnostic test software source code response file utilizing the computer only if the hash code in the diagnostic test software source code file is identical to the hash code in the diagnostic test software source code response file.

11. The method of claim 1, wherein the diagnostic test software source code response file further includes a scheduling array that includes an index associated with the first diagnostic test for scheduling execution of the first diagnostic test.

12. A system for generating diagnostic test files associated with a battery pack, comprising:

a memory device having a diagnostic test data table with a plurality of records stored therein, a first record of the plurality of records being associated with a first diagnostic test of the battery pack, the first record having a first parameter identifier, a first value associated with the first parameter identifier, a second parameter identifier, a second value associated with the second parameter identifier, a fault threshold identifier, and a fault threshold value associated with the fault threshold identifier;
