Z-serial device Ra-table update range

Resistance updates happen at grid-point every 10% of discharge, and below 20% SOC about every 3.3% of discharge.

At each grid point, limit for update is no more than 3 times change either up or down.

It is also not allowed to become negative.

If either limit is exceeded, R_DIS flag in Operation Status will be set and resistance updates

are disabled until next relaxation will allow an OCV reading.

This limits start after optimization cycle is finished and Update Status = 6 is shown.

Resistance flags will change from FF55 to 0055.

Before optimization cycle is complete, there is no limits. That is why it is important

to perform optimization cycle starting with default values, so that no limits will interfere

with learning.

There is no limit for absolute value, except signed integer range 2^15.

Dear Yevgen:

Thanks your providing information!

Ra-table reduces limit is 3 times or 0.3 times? up is 3 times.

Therefor, IT enable is very important while cell must in the relaxation mode.

Coudl  you please tell me conditions of the R_DIS flag raise?

Example:

1. Ra-table update over 3 times.  

The Second questions:

• If IT enable while cell in active mode,how many parameter happen error?
• And whether can recover normally? 

Best Regards!
