bq27531EVM - Does TI provide a way to automatically run charge/discharge cycles?

Other Parts Discussed in Thread: BQ27531-G1, EV2400, BQ24192

Still trying to optimize the cell performance with our bq27531-G1 EVM kit. Is there a way to automatically run charge/discharge cycles from GaugeStudio or other eval SW and log the data?

* Discharge: Disabling charging and OTG on the bq24192, turn on an external load-FET via EV2400.

* Delay timer

* Charge: Enable charging on the bq24192, turn off external load-FET.

* Delay timer

* etc...

I'm still not sure I've set up the cell parameters and learning cycle correctly, and connecting/disconnecting loads is a pain to do throughout the day.

Many thanks

There is no automated way to run chg/dsg cycles. To make things easier, you can completely bypass the charger, however. Just connect a power supply to the SYS (J5) terminal block. This will at least save some steps with enabling and disabling the charger.

Is it possible to force BATFET off from GaugeStudio?

I tried writing to 7C and reading back, the value did not change.
