Yes, most EVs will continue to charge at a slower rate above 80 per cent. I've not driven an electric car which won't drop below 10 per cent. EVs are at their best when you can charge overnight at home and then rarely travel further than their range in a day, meaning you don't have to be concerned about charging in public. That said, I've covered hundreds of miles in electric cars in a day and charging is getting easier than it used to be. I usually want to stop for a refreshment break before the car needs charging.
