Battery Health Summary

  • •Battery health is excellent. Continue normal charging habits.
  • •NMC battery: daily charging to 80–90% extends long-term health. Reserve 100% for long trips.
✅

Optimisation Tips — Your Battery is in Great Shape

  • 1.Your battery health is excellent — great charging habits are working.
  • 2.Continue charging to 80% for daily use and only to 100% for long trips.
  • 3.Avoid leaving the car in extreme heat (above 35°C) for prolonged periods.
  • 4.Maintain consistent moderate-speed driving — aggressive acceleration increases heat generation.
  • 5.Keep software updated — OEM firmware often includes improvements to BMS charging algorithms.

Charging Guidance for NMC Chemistry

⚡Daily Charging (NMC)

  • ✓Set your charger limit to 80% for everyday driving — this significantly extends battery life.
  • ✓Only charge to 100% when you need maximum range for a long trip.
  • ✓Avoid letting the battery drop below 10% regularly — deep discharge accelerates degradation.
  • ✓Charge at home overnight using Level 2 AC charging where possible — slow charging generates less heat.
  • ✓Avoid DC fast charging for every session. Use it when convenience is critical, not as the default.

⚡Long-Term Storage (NMC)

  • ✓Store at 50% SOC if leaving the vehicle unused for more than 2 weeks.
  • ✓Avoid leaving at 100% charge for more than 24 hours — it stresses the cells.
  • ✓Keep the vehicle plugged in if your charger supports scheduled charging, to allow thermal management.
