That sounds about right, if it takes all night to charge. The Tesla supercharger can add 200 miles of range in 15 minutes, which I think is more important than overall max range. But the battery pack still has to be substantial enough to absorb that much energy at that speed, and offer reasonable performance after accounting for a few years of age degradation.
