Identified Risks
High DC fast charge usage (38%)high impact
Fix: Use AC Level 2 for regular charging. Reserve DC fast for travel only.
Frequent full 100% charges (40% of sessions)high impact
Fix: Set vehicle charge limit to 80% in app settings.
Charging Prescriptions
Reduce DC Fast Charging to ≤ 20% of sessionshigh
Each fast charge session increases cell stress by 3–5×. Reducing frequency extends usable battery life by up to 1.8 years.
Now: 38% of sessions use DC Fast / Supercharger
Target: Max 1 fast charge per week. Use AC Level 2 for regular charging.
+1.2 yr battery life · $360 in degradation costs per year
Set daily charge limit to 80%high
Charging to 100% regularly accelerates electrolyte oxidation in NMC chemistry. Limiting to 80% extends cycle life by up to 40%.
Now: 40% of sessions charged to 100%
Target: Daily limit: 80%. Charge to 100% only before long trips.
+1 yr battery life
Predictive Maintenance Schedule
PlannedJune 2027
Battery Health Inspection
Scheduled health inspection based on current SOH of 96.4%. Inspection every year recommended.
$95–$160+4 mo life
Full diagnostic scan including BMS logs, capacity test, and cell impedance check.
PlannedDec 2026
BMS Software Update
Manufacturer BMS updates often improve cell balancing algorithms and charge curve accuracy, extending usable life.
Free+6 mo life
Check for OTA updates via vehicle manufacturer app. If unavailable, request update at next service.
MonitorMar 2027
NMC Electrolyte Check
NMC chemistry is sensitive to high SOC storage and elevated temperature. Electrolyte condition degrades faster above 85% regular charge level.
$80–$140+18 mo life
Set charge limit to 80% for daily use. Only charge to 100% before long trips.
