format: aaAAbbBBccCCddDDeeEEffFFggGGhhHHiiIIjjJJkkKKllLL
where:
AAaa: True Rem Q. True remaining capacity in mAh from IT
simulation before any filtering or smoothing function. This value can
be negative or higher than FCC.
BBbb: True Rem E. True remaining energy in cWh from IT simulation
before any filtering or smoothing function. This value can be
negative or higher than FCC.
CCcc: Initial Q. Initial capacity calculated from IT simulation
DDdd: Initial E. Initial energy calculated from IT simulation
EEee: TrueFullChgQ. True full charge capacity
FFff: TrueFullChgE. True full charge energy
GGgg: T_sim. Temperature during the last simulation run (in 0.1K)
HHhh: T_ambient. Current estimated ambient temperature used by
the IT algorithm for thermal modeling
IIii: RaScale 0. Ra table scaling factor of Cell1
JJjj: RaScale 1. Ra table scaling factor of Cell2
KKkk: CompRes1. Last computed resistance for Cell1

IIii: DOD0_1. Depth of discharge for Cell1
JJjj: DOD0_2. Depth of discharge for Cell2
KKkk: DOD0 Passed Q. Passed charge since DOD0
LLll: DOD0 Passed Energy. Passed energy since the last DOD0
update
MMmm: DOD0 Time. Time passed since the last DOD0 update
