Is Charging to 80% Better?

Published in EV Charging Strategy 1 min read

Yes, charging an electric vehicle (EV) to 80% instead of 100% is often better for both charging speed and battery lifespan.

Why 80%? The Benefits

Charging to 80% offers two key advantages:

  • Faster Charging: Charging rates significantly decrease as you approach 100%. This means you'll spend considerably less time plugged in if you stop at 80%.

  • Extended Battery Life: Keeping your EV's battery below 100% consistently helps prolong its lifespan. The stress of a fully charged battery can contribute to degradation over time.

Practical Implications

Consider these scenarios:

  • Daily Commute: Charging to 80% provides ample range for most daily commutes, and you'll avoid the slow charging at the end of the process.

  • Long Trips: You can top up to 80% at various charging stops during a long journey, optimizing charging time without sacrificing substantial range.

This strategy balances convenience and battery health, maximizing both your charging efficiency and the longevity of your EV's battery. The reference material supports this by highlighting that charging slows dramatically past 80% and that keeping the battery below 100% improves long-term health.
