Several factors can reduce the lifespan of an electric vehicle (EV) battery, including:
Factors Affecting EV Battery Lifespan
1. Temperature
- High Temperatures: Accelerate chemical reactions within the battery, leading to faster degradation and reduced efficiency over time.
- Low Temperatures: Can temporarily reduce battery range and efficiency, though the long-term impact is less severe than high temperatures.
2. Operating State of Charge
- Overcharging or Deep Discharging: Regularly charging to full capacity or letting the battery drain to zero can strain the battery, reducing its lifespan. Keeping the charge between 20% and 80% is recommended.
3. Charging Habits
- AC vs. DC Charging: Frequent use of DC fast charging can lead to faster battery degradation compared to slower AC charging.
- Charging Frequency and Rate: Faster charging can increase the temperature of the battery, potentially leading to more strain and degradation.
4. Usage (Energy Cycles)
Each charge-discharge cycle slightly impacts the battery’s capacity, with more cycles leading to gradual degradation.
5. Battery Chemistry
Different lithium-ion chemistries, such as NMC or LFP, vary in durability and longevity.
6. Battery System and Thermal Management
Effective thermal management systems, such as liquid cooling, can significantly reduce degradation compared to passive air cooling systems.
7. Storage Environment
Higher storage temperatures can accelerate calendar aging, impacting battery health if not properly managed.
8. Age
Age is a natural factor in battery degradation, with capacity reducing over time due to internal chemical changes.
