Other Parts Discussed in Thread: BQ76920,
I recently did test to measure Cell voltage, Temperature and Charge(or Discharge) Current using bq76920 EVM.
Referring to the User's manuer of EVM and demo video , I did this procedure.
I connected Power supply to 'Batt' terminals and check whether the parameter value(Cell Voltage1~5, Battery Voltage, Temp Sensor) is correct. everything is ok.
And I set Configurations like this.
And I connected Electronic Load to Pack terminals(CC mode)
But I cannot read Coulomb Counter. Coulomb Counter value is always zero at the Evaluation Software. (I did I2C connection correctly.)
(I connected Power supply and Electronic Load like this)
I don't know what should I do.
Please give me advice.
Thanks.
