This command instructs the device to return Impedance Track™ related gauging information on ManufacturerBlockAccess() or ManufacturerData().
| Status | Condition |
|---|---|
| Activate | 0x0074 to ManufacturerBlockAccess() or ManufacturerAccess() |
Action: Output 32 bytes of IT data values on ManufacturerBlockAccess() or ManufacturerData() in the following format: AABBCCDDEEFFggGGhhHHiiIIjjJJkkKKllLLmmMMnnNNooOOppPPqqQQrrRRssSS where:
| Value | Description | Unit |
|---|---|---|
| AA | Pack Grid. Active pack impedance grid point (minimum of Cell Grid 0 to Cell Grid 3). This data is only valid during DISCHARGE mode when [R_DIS] = 0. If [R_DIS] = 1 or not discharging, this value is not updated. | — |
| BB | 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 update in field 0 = QMax has not been updated in the field. 1= QMax updated in the field. | — |
| CC | Cell Grid 0. Active grid point of Cell 1. This data is only valid during DISCHARGE mode when [R_DIS] = 0. If [R_DIS] = 1 or not discharging, this value is not updated. | — |
| DD | Cell Grid 1. Active grid point of Cell 2. This data is only valid during DISCHARGE mode when [R_DIS] = 0. If [R_DIS] = 1 or not discharging, this value is not updated. | — |
| EE | Cell Grid 2. Active grid point of Cell 3. This data is only valid during DISCHARGE mode when [R_DIS] = 0. If [R_DIS] = 1 or not discharging, this value is not updated. | — |
| FF | Cell Grid 3. Active grid point of Cell 4. This data is only valid during DISCHARGE mode when [R_DIS] = 0. If [R_DIS] = 1 or not discharging, this value is not updated. | — |
