While there is no specific data indicating that certain EV models are more susceptible to battery degradation from DC fast charging, the general consensus is that frequent use of DC fast charging can slightly increase the rate of battery degradation across various EV models. Here are some key points:
General Impact on EV Batteries
- Overall Impact: DC fast charging may contribute to a somewhat higher rate of battery degradation compared to slower charging methods, but the effect is typically minimal.
- Studies and Data:
- Research from the Idaho National Laboratory found a slight increase in battery capacity loss with DC fast charging compared to Level 2 charging, but the difference was minimal.
- Another study observed a 16% increase in degradation when using DC fast charging compared to AC fast charging in Nissan Leafs.
Specific Conditions Affecting Degradation
- Climate: Vehicles in hot climates tend to experience more pronounced battery degradation when frequently using DC fast charging.
- Charging Frequency: Frequent use of DC fast charging can exacerbate degradation more than occasional use.
- Vehicle Maintenance Tips: Preserving battery life involves limiting DC fast charging, avoiding extreme temperatures, and maintaining a balanced state of charge.
Given the lack of specificity in current research regarding model-specific susceptibility, it’s advisable for all EV owners to follow general best practices to minimize battery degradation, regardless of their vehicle model.
