Description

This creation is about a calibration device; more specifically, it is about an automatic calibration device for voltage and temperature of the battery control board.

Generally, the inspection method for battery packs on the production line is to test the battery control board and the battery cell after the assembly is completed, but the disadvantage of the inspection after assembly is that once the battery pack is found to be defective, it is necessary to go further to deal with the battery. It still takes more time for the control board to have problems with the battery cells.

The above two correction step methods will use the first correction method that first corrects the voltage and then the temperature is better than the second correction method that first corrects the temperature and then corrects the voltage. The reason is that the temperature must be corrected when the temperature is detected. The battery control board 2 can only be measured after powering on for a period of time. Therefore, if the voltage test can be performed immediately after the power is turned on, when the voltage test is over, the battery control board 2 to be calibrated will usually reach the temperature test directly status.

Then, if the detected result falls within the error value, the calibration board 12 can directly issue the lock board command and write the production history into it, and the display device 14 will display the completed diagram to complete all calibration operations. The operator observes, and if the detection result is not within the error value, the operator only needs to press the calibration button 15 and let the calibration board 12 automatically adjust the temperature and voltage parameters of the battery control board 2 and let the detection result fall within the error value Afterwards, the calibration board 12 then issues a lock board command and writes the production history into it, so that the operator only needs to confirm whether the final data is normal, and does not need to follow the cumbersome calibration process to operate one by one.

Finally, when the battery control board 2 completes the calibration work, the operator can remove it and perform the next battery control board 2 calibration work, and the completed battery control board 2 can be handed over to other operators for follow-up Battery pack assembly.

In summary, the voltage and temperature automatic calibration device and the calibration method for the battery control board of the present invention have the advantage that the inspector only needs to check the relevant parameters displayed on the display device 14 to immediately know whether the battery control board 2 needs to be validated or not. And during the calibration process, the operator only needs to press the calibration button 15, the calibration board 12 will automatically adjust the parameters of the battery control board 2 to make the test results meet the standard.
