In both BPX JSON example files, there is a numerical error in the expression of the "Entropic change coefficient [V.K-1]" for the graphite (negative electrode) material.
The numerical value is in mV/K, not V/K. This leads to unphysical behaviour when the BPX JSON is used at temperatures other than the reference temperature (25[degC]).
The expression includes a lengthy redundant term which is multiplied by 0.
