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, across every pack topology the catalogue knows.

Where the number comes from
Hanterill reads state of health from the battery controller. Where supported, it also reads learned cell capacity and compares it with the reference for your battery to show capacity loss.
What Hanterill reads
- State of health and state of charge
- Pack voltage and pack current
- Every cell-group potential on the active pack topology (108 on CMA: 27 modules, 4 groups each)
- Minimum, maximum and delta across cell groups
- Pack and module temperatures, rendered as a thermal grid
- Learned cell capacity compared with the battery's reference, where available
- Cross-signal checks: reported pack voltage against the cell sum, reported power against calculated
Pack topologies
Battery layouts differ between models. Hanterill chooses the matching layout so it does not mistake an expected gap for a missing cell group. CMA has the most complete real-car verification; other layouts still need testing on more vehicles.
