How Quickly Do EV Batteries Lose Range Over Time?

Key Points:
- Battery degradation in electric vehicles (EVs) is similar to mobile devices and laptops: batteries naturally degrade over time.
- EVs depend heavily on their batteries since they lack traditional engines like internal combustion vehicles.
- Extreme temperatures (hot and cold) mimic battery degradation by reducing range and slowing charging speeds.
- Preservation Tips:
- Park EVs away from extreme temperatures or in a garage to protect the battery from temperature extremes.
- Avoid fully charging the battery every time—keeping the charge between 20-80% is optimal for battery longevity.
- Don't let the battery discharge completely; try to plan trips with a buffer to prevent draining to 0%.
- Avoid using fast chargers too frequently as it causes wear and tear on the battery, leading to premature failure.
- Repeated use of launch controls or high-speed driving can damage the battery and degrade its capacity faster.
- Battery Life Expectancy:
- Most EV batteries last around 100,000 miles before showing noticeable signs of degradation.
- Manufacturer warranties typically cover up to 70% capacity, so even if the battery loses 20-30% of its range, it may not be considered a warranty issue.
- Charging Concerns:
- Access to chargers isn’t as critical as the time it takes to charge. Charging can take 1.5-2 hours, which can be as long as driving to the next charging station.
- Fast charging, when used too often, can void warranties from some manufacturers.
- Tips for Buying Used EVs:
- Always test the battery condition beforehand to ensure the battery is not already near the end of its life.
Conclusion:
- Maintaining an EV battery requires mindful charging, driving habits, and climate considerations. Regular monitoring and care will help preserve battery life and ensure optimal performance.
