Battery Life/Degradation was created by NM_90

Hi,

I was curious to know if the data/calculation method used in SAM for Battery Life are the same than the ones used in the BLAST tool from NREL?

If not, do you know what are the differences between each tool? And would you know how to get access to the BLAST-S version of the tool?

Thank you,

Nicolas.

Hi Nicolas,

SAM's battery life model for Li-ion NMC/Gr batteries is based on the same model as the one used in BLAST. That model is described in Smith, K.; Saxon, A.; Keyser, M.; Lundstrom, B.; Cao, Z.; Roc, A. (2017). Life Prediction Model for Grid-connected Li-ion Battery Energy
Storage System. Presented at 2017 American Control Conference. ( PDF 1.4 KB ).

You can find references to that publication and others describing SAM's battery model here: sam.nrel.gov/battery-storage/battery-publications.html

Best regards,
Paul.
