⚠️ Cell voltage imbalance detected — voltage spread exceeds 50mV threshold. Recommend BMS diagnostic.
Recommendations
1
Battery health is poor. Schedule a dealer diagnostic assessment.
2
Check if vehicle is within warranty — most OEMs cover <70% SOH within 8 years/160,000 km.
3
High degradation rate (6.6%/year). Check for frequent DC fast-charging or extreme temperature exposure.
4
Cell voltage imbalance detected. One or more cell groups may be underperforming. Dealer diagnostic recommended.
5
NMC battery: daily charging to 80–90% extends long-term health. Reserve 100% for long trips.
6
Projected to reach 80% SOH in ~0.0 years. Plan for battery assessment soon.
