⚠️ Cell voltage imbalance detected — voltage spread exceeds 50mV threshold. Recommend BMS diagnostic.
Recommendations
1
Battery health is fair. Limit DC fast-charging to essential use only.
2
Avoid charging above 80% or depleting below 20% regularly.
3
High degradation rate (7.8%/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.
