Recent tests on a high-mileage 2019 Tesla Model S reveal that while EV battery longevity seems promising, charging takes significantly longer as the battery ages. A full charge from flat to 100% took 2 hours and 41 minutes. The last stage of charging (80-100%) contributed to over half that time, mainly due to battery management recalibration. Charging from 10-80% took a more reasonable 47 minutes, suggesting that charging practices significantly affect the overall experience with aging batteries.
Going from fully flat to fully charged took a whopping 2 hours and 41 minutes. That sounds awful. But don't give up on high-mileage EVs just yet, as the nuanced version is a lot less dire than the top-line number.
Well over half of that time was just spent getting the Model S from 80-100%. If you know about batteries, that shouldn't surprise you.
The Tesla Model S charged from 10-80% in about 47 minutes, which really isn't too terrible.
That process gets harder as batteries degrade, and harder still if the battery is not properly calibrated and balanced.
