I am comparing simulated vs experimental values of Current pulse discharge test of LiFePo4 2.5Ah battery. The maximum error value I get is 21mV and mean is 10mV. Is it acceptable ? What is the acceptable RMSE for a battery model ?
Hi, At 1C-rate, I am doing OCV test on A123 li-ion cyclindrical cells to measure capacity & internal resistance. At the end of discharge cycle how long is the pause time after which I can...
