Battery Health & Fast Charging – FAQ
Does fast charging always damage my EV battery?
Fast charging does cause more stress on the battery compared to slower AC charging, but modern EVs have sophisticated battery management systems to mitigate this. Occasional fast charging won’t significantly harm your battery, but frequent use over time can accelerate degradation.
Is it bad to charge my battery to 100%?
Charging to 100% occasionally for trips is fine, but keeping your battery at high states of charge for extended periods can accelerate degradation. For daily use, charging to 70-80% is recommended to extend battery life.
What is the best state of charge to store my EV?
If you’re storing your EV for an extended period, the ideal state of charge is around 40-60%. This minimizes stress on the battery cells and helps maintain long-term health.
How accurate is this battery health estimate?
This tool provides a general estimate based on common factors that affect battery degradation. Actual battery health can vary based on specific vehicle model, battery chemistry, software updates, and individual usage patterns. Always consult your vehicle’s manufacturer for the most accurate assessment.
