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.
