Hi there,
I've been unsuccessfully trying to calibrate a battery for a few days now. I am using the bq27500 in my own design and I2C communication is working fine. For calibrating the battery, I am using EV2300. Regarding that, I have a few questions:
1) On my first device, the Impedance Track Configuration Wizard in bqEasy got stuck on "1B. Load .DFI-File". While is was loading the DFI-file to the bq27500, it made a break and didn't continue. Since then, the bq27500 on my device isn't accessible any more, neither with I2C on my host software, nor by the EV2300 using bqEasy. Is there any way to reset the bq27500 to make it work again?
2) On the second device, everything works fine when using the Impedance Track Configuration Wizard. For calibrating the battery, I discharged it to empty and waited for 5 hours. After that, I clicked the "Initialize Impedance Track Algorithm". The IT Enable turned to 1, which is fine, but the VOK and QEN bits stayed 0. This means Impedance Track won't work, right?
I made some screenshots of my configuration. These were taken after I initialized the Impedance Track Algorithm.
Could you please tell me, if there is anything wrong about it?
Thanks in advance for your help!
Regards,
Julian
