How long does electric vehicle battery last?

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).
