Terminal voltage error and SOC estimation error.

Cases estimating SOC of the old battery		SOC estimation error
Case 1: all parameters are the new battery’s ones	mV
Case 2: only the OCV is the new battery’s one	mV
Case 3: only the OCV is the old battery’s one	mV
Case 4: all parameters are the old battery’s ones	mV
