Hello,
I'm evaluating the BQ40Z60-EVM with 3 LI-ION batteries with the following characteristics:
Nominal Capacity - 860mA.
Nominal Voltage - 3700mV
Charge Current - Standard 0.2C, Max 1C
Charge cut-off Voltage - 4200mV
Standard Discharge Current - 0.2C
Standard Discharge Current - 2C
Discharge cut-off Voltage - 2750mV
Impedance - 300mOhms
After setting some parameters in BMS, I'm facing some issues:
- Battery charge status is not showing the correct values in percentage.
- Max Error is reporting 100%
- During charging, BMS report Charge Overload, but only one of the batteries reach 4200mV, and the other two has 3800mv and 3900mV respectively. Which looks like that the battery balance is not working.
Attached the gg.csv file.
