Key factors affecting battery lifespan:
- Temperature extremes: Very high or low temperatures can accelerate battery degradation or reduce performance.
- Charging habits: Frequent fast charging and charging to 100% (or discharging to 0%) can shorten battery life.
- Driving behavior: Aggressive acceleration, high speeds, and heavy loads increase energy demand and wear on the battery.
- Battery chemistry and management: Modern EVs use battery management systems (BMS) to optimize charging, cooling, and usage, helping to extend lifespan.
Proper care — like avoiding extreme states of charge and using temperature-controlled charging — can significantly improve long-term battery health.
