The percentage, and the numbers behind it.
Hanterill reads high-voltage battery data reported by the vehicle: state of health and charge, pack voltage, cell-group distribution, imbalance and temperature.
State of health
- Source
- Vehicle BMS
- Updated
- Live
- Condition
- Good
Representative interface with sample values. Not a live vehicle reading.
Where the number comes from
State of health is reported by the battery management system, not calculated by Hanterill. Hanterill reads it, and the values behind it, directly from the vehicle.
What Hanterill reads
- State of health and state of charge
- Pack voltage and pack current
- All 108 cell-group potentials on CMA (27 modules, 4 groups each)
- Minimum, maximum and delta across cell groups
- Pack and module temperatures
- Estimated usable capacity against nominal
Switch the panel to Engineering for the control module, transport, service and identifiers. Battery diagnostics docs have the full read sequence.
