How long does electric vehicle battery last?

The lifespan of an electric vehicle (EV) battery typically depends on factors like battery chemistry, usage patterns, charging habits, and climate. However, here's a general breakdown:

1. Average Lifespan

  • 8 to 15 years under normal driving conditions.

  • 100,000 to 300,000 miles (160,000 to 480,000 kilometers) depending on battery quality and usage.

2. Warranty Coverage

  • Most EV manufacturers offer battery warranties of 8 years or 100,000–150,000 miles, whichever comes first.

  • For example:

    • Tesla: 8 years, 100,000–150,000 miles depending on the model.

    • BYD and Nissan: Similar 8-year coverage.

3. Factors That Affect Battery Life

  • Temperature: Extreme heat or cold shortens lifespan.

  • Charging habits: Frequent fast charging or keeping battery constantly at 100% or 0% can degrade it faster.

  • Driving style: Aggressive driving accelerates wear.

  • Battery management system (BMS): A good BMS helps maintain longevity.

4. Degradation Rate

  • EV batteries typically lose about 1–2% of capacity per year.

  • After 8–10 years, many still retain 70–80% of their original capacity.

5. Second Life

  • When an EV battery can no longer power a vehicle efficiently, it can often still be reused for energy storage systems (home or grid use).
