As the figure above, the customer charges and discharges the four-battery charging and discharging device with the BQ40Z50EVM.
ISSUE:
1. The current does not change. For example, after calibration with discharge 1.8 A, the current measurement remains same, and the charge shows -1800 mA.
2. The soc of the cell has been incorrectly measured.
3. Battery voltage consistency is poor when charging with the board.
4. TDA remains high, FD remains high.
Could you please help check these?
Thanks!
Best Regards,
