Problem Description:
1. When the 0.5C 1.0C discharge accuracy is verified, there is a jump, and there is no jump at 0.2C, based on the normal temperature test.
0.5C discharge accuracy deviation 0%~﹢18% RSOC jump amplitude 15%.
1.0C discharge accuracy deviation 0%~﹢44% RSOC jump amplitude 39%.
Remarks: Polymer batteries, 3S4P combination, full charge voltage is 4.35V, step-down 4.2V is used.
2. Are the following three parameter settings reasonable?
Fixed EDV 0 -->3200mV
Voltage 100% DOD-->3401mV
OCV11 DOC 0%-->3409mV
3. Would lowering the EDV2 voltage and increasing the EDV2 delay fix the problem?
4. Is there any other way to optimize this jump?
