Charging Best Practices

The battery is the most expensive component of an electric vehicle, and maintaining its health is crucial. A healthy battery ensures optimal performance, range, and vehicle longevity. On the other hand, an unhealthy battery can reduce driving range, slow acceleration, and negatively impact the resale value of your EV.

Best Practices for Charging Your EV Battery

1. Avoid Deep Discharging Lithium-ion batteries used in most EVs perform best when the battery level stays between 20% and 80%. Avoid draining the battery completely or overcharging it to extend its lifespan.

2. Charge Regularly Unlike gasoline-powered cars, EVs thrive on regular charging. Don’t wait until the battery is almost empty before charging. Regular charging helps prevent deep discharges and can be conveniently done overnight at home when electricity rates are lower.

3. Use a Level 2 Charger Level 2 charging is faster and more efficient than Level 1, helping to maintain the battery’s temperature in its optimal range. Installing a Level 2 charger at home is a worthwhile investment for daily charging needs.

4. Avoid Rapid Charging Fast charging (also known as rapid charging or supercharging) can stress the battery and accelerate degradation. Use this method sparingly and only when necessary, such as during long trips.

5. Avoid Extreme Temperatures Prolonged exposure to extreme temperatures—either above 86°F or below 32°F—can degrade battery health. Whenever possible, park your vehicle in a garage or shaded area to protect the battery from extreme heat or cold.

6. Don’t Overcharge Overcharging can harm the battery, so stop charging once it reaches 100%. Many EVs have built-in systems to prevent overcharging, but it’s still a good habit to monitor charging sessions.

7. Use Regenerative Braking Regenerative braking captures energy during deceleration and feeds it back into the battery. This feature not only improves efficiency but also reduces strain on the battery.

8. Use Preconditioning Many EVs have a preconditioning feature that heats or cools the battery before driving. Preconditioning optimizes battery performance and reduces stress caused by extreme temperatures.

9. Regulate Your Driving Habits Smooth driving habits—such as avoiding sudden acceleration and hard braking—help protect the battery. Using features like adaptive cruise control can also help minimize battery strain.

10. Monitor Battery Health Most EVs come equipped with a battery management system (BMS) that provides important data on state of charge and battery health. Regularly check this information and address any issues promptly to maintain battery performance.
