Texas Instruments BQ28Z610-R2 User Manual

Status Condition Action
Activate 0x0073 to MACSubcmd()
Outputs 24 bytes of IT data values on MACData() in the following
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
LLll: CompRes2. Last computed resistance for Cell2
12.2.40 MACSubcmd() 0x0074 ITStatus2
This command instructs the device to return Impedance Track related gauging information on MACData().
Status Condition Action
Activate 0x0074 to MACSubcmd()
Outputs 24 bytes of IT data values
on MACData() in the following format:
AABBCCDDEEFFggGGhhHHiiIIjjJJkkKKllLLmmMMnnNNooOO
where:
AA: Pack Grid. Active pack grid point (only valid in discharge)
BB: LStatus—Learned status of resistance table
Bit 3 | Bit 2 | Bit 1| Bit 0
QMax | ITEN | CF1 | CF0
CF1, CF0: QMax Status
0,0 = Battery OK
0,1 = QMax is first updated in learning cycle.
1,0 = QMax and resistance table updated in learning cycle
ITEN: IT enable
0 = IT disabled
1 = IT enabled
QMax: QMax field updates
0 = QMax is not updated in the field.
1= QMax is updated in the field.
CC: Cell Grid 1. Active grid point of Cell1
DD: Cell Grid 2. Active grid point of Cell2
EE: N/A. RSVD
FF: N/A. RSVD
HHhhGGgg: State Time. Time passed since last state change
(Discharge, Charge, Rest)
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
NNnn: DODEOC_1. Cell 1 DOD@EOC
OOoo: DODEOC_2. Cell 2 DOD@EOC
12.2.41 MACSubcmd() 0x0075 ITStatus3
This command instructs the device to return Impedance Track related gauging information on MACData().
