I read multiple documents and forum posts about the correct way of going through a learning cycle, but each of them is slightly different from each other.
The materials I read so far:
- The famous Achieving The Successful Learning Cycle (SLUA903)
- How to perform a successful learning cycle with gauges | TI.com Video
- Learning Cycle Overview - TI E2E
- Multiple forum posts
The ways mentioned in those materials falls into 2 major types:
- (1) Discharge to end and relax 5 hours (2) Enable IT (3) Charge to full (4) ...
- (1) Enable IT (2) Reset (3) Discharge to end and relax until VOK & RDIS are cleared (4) Charge to full (5) ...
I'm currently using type 2. I only have a limited number of success using it.
Now my problem is sometimes the VOK never sets.
- VOK is cleared before I send IT Enable & Reset. After sending them and starting the initial discharge, it's still cleared. Since I need to "relax until VOK & RDIS are cleared", VOK must be set sometime earlier. When will it be set?
- In the above situation, only RDIS is set after IT Enable & Reset. RDIS will be cleared as excepted in the end of the first discharge relax. But VOK won't be set for a single time in the process, even when the charging is started.
So please also clarify these points:
- Say if I have a brand new gauge, which type of procedure mentioned above is more correct? If none of them are 100% correct, please tell me the 100% correct one.
- For gauges without a REST bit, how to know if the gauge thinks the battery is fully relaxed?
- When will VOK be set or cleared?
I want 100% correct answers of these questions, not copy pasta from older forum posts with ambiguous answers.
Thank you!
