Other Parts Discussed in Thread: BQ34Z100, BQ34Z100-G1, BQEVSW, BQSTUDIO, EV2400,
Greetings,
I am trying to develop a Battery Monitoring System with TI’s BQ34Z100 /BQ34Z100-G1, ESP32 as host micro-controller (communicates through I2C with the IC).
For evaluation I am using the BQ34Z100 EVM, connected to an ESP32 via I2C.
The battery used is a 3.3V Lithium-ion battery with 2 cells connected in parallel. The capacity is 3000mAh and the energy is 11.1Wh.
The BQ34Z100 EVM was purchased from Digikey. The EV2300/2400 module was not purchased.
The BQ34Z100 EVM was found to contain a data flash memory map which did not match the one in the latest datasheet of BQ34Z100 / BQ34Z100-G1.
From TI’s forum, it was found that Digikey ships the same EVMs or ICs which are outdated. Below links confirm the same.

Link3
Link4
Also got hold of the datasheet matching the outdated EVM which we have, from the same forum post.
Please refer to the attached datasheet along with this post. The latest datasheet on TI website will not be useful for resolving the query.

Connection diagram:
******************************************************************
After making the necessary configurations to the EVM w.r.t to the battery we are using, the following was observed.
Standard Data Commands (Table 2 , Page no. 10):
- The Voltage of the battery, Temperature is being read consistently without any issues.
- The parameters such as State of Charge, Remaining capacity, Full Charge capacity give out some data, but it is not accurate. The data may not be due to the fact that we have not performed any complete learning cycle.
But the Average Current from Standard Data Commands and the Current parameter from Control() Subcommands are always 0. (even when 300mA of current is indicated in the Multimeter). Both in SEALED and UNSEALED states.
Query:
What are the cases the current might become zero. How can we resolve this issue?
******************************************************************
Configurations made
I have added all the configurations made to the BQ34Z100 EVM by specifying all the values (in VALUE FROM DEVICE column) in the data flash and output of Data, Extended data commands
No current or voltage calibration has been performed in the BQ34Z100 EVM
NOTE: Tables represented below are taken from the datasheet matching with the EVM which we have.
