Identified Risks
Frequent full 100% charges (27% of sessions)high impact
Fix: Set vehicle charge limit to 80% in app settings.
Charging Prescriptions
Set daily charge limit to 80%high
Charging to 100% regularly accelerates electrolyte oxidation in LFP chemistry. Limiting to 80% extends cycle life by up to 40%.
Now: 27% of sessions charged to 100%
Target: Daily limit: 80%. Charge to 100% only before long trips.
