Other Parts Discussed in Thread: BQSTUDIO,
Hi, I have few more questions regarding previous discussions on power management forum about learning cycle process on bq4050 by bqstudio:
1)slua848 describes the method for successful learning cycle , how ever it is not relevant for bq4050 . slua848 tells that the learning cycle will update Ra table and Qmax- both are not included at the bq4050 data memory. so, which registers does the learning cycle process update?
2)slua848 say that the user should modify the "update status" field- again , it's not included at bq4050 data memory- so , during the learning cycle - does the user should press anything ?
3) how long do you suggest to relax between charge and discharge (at learning cycle) ? for good OCV measurement ( or it's not relevant here either?)
4) Will the bq4050 continue to update the registers of your answer for question num. 1 for each charge-discharge cycle?
5)after we've inserted the GPC parameters into data memory (bqstudio) the capacity shown at auto refresh panel is 100% when we connect the charger, HOWEVER , the expected capacity is only ~10%.
what can be the reason for this error?
I attach the gpc results here:
SOC, % OCV, mV
0 2605
10 3192
20 3237
30 3265
40 3277
50 3281
60 3285
70 3302
80 3323
90 3327
100 3419
EMF 3215
EDVC0 115
EDVC1 0
EDVR1 1
EDVR0 6450
EDVT0 4119
EDVTC 9
I could not find the register for the next 3 parameters:
VOC75 11806
VOC50 11425
VOC25 11256
Are they relevant?
6) Are these the only registers from the gpc tool we should write to data memory ?
