Part Number: BQ27441EVM-G1A

Tool/software:

Battery Management Studio (BQS) is giving the warning message. 'This device is already in the 'Learned' state. If you choose to continue, the device's state will change to 'Unlearned'. This will require the learning cycle to be completed again. Are you sure you want to continue ?

1. What to do in this situation, if I press 'No', then the learning cycle will be completed automatically and parameters will be updated ?

Attached is the screenshot, every time i am pressing start, it is showing the screen above, then it lands to different block, so it is performing learning cycle on its, any option to resume the learning cycle and see the status if the USB-cable is removed?

I am using EVM2400, can it do automatic learning cycle ?
I am doing the manual learning mode, it needs to remove load, add load after every certain step. How can i do that using the 'view the update status register' ?

Hi,

There is no automatic learning cycle.

There is no step where you remove the load.

Please follow this documentation. Achieving The Successful Learning Cycle (tij.co.jp)

Hi,

If this message appears when you first begin a learning cycle then there is no learned information to lose. So, you can disregard this message but please complete the full learning cycle in 1 attempt.

Evan
