it can charge from 15 percent to 80 percent of battery capacity in 44 minutes.

So, let's use the worse case scenario: 15% in 44 minutes. To fully charge the vehicle would take: 4.9 hours.

Ford claims a driving range of 230 miles per charge; upgrading to the larger pack boosts driving range to 300 miles.

230 miles is a 3 hour trip on the interstate (300 is 4 hours). What the time would be in stop and go traffic is anybody's guess.

I'm going to assume the 4.9 hour charge time is for the 230 mile driving range. For the 300 mile range battery it would be: 6.4 hours.

You're reading it wrong. This means that it can take a discharged battery FROM 15% OF CHARGE TO 80% OF CHARGE in 44 minutes...............

You're missing a major caveat here, if Ford's numbers are like the ones Tesla advertises. Those quick charge times are ONLY on a high-voltage Supercharger station. If you have the home installed 220V charger, it's something like double that time, 8-12 hours. If you're plugging it into your regular 120V outlet, it's a day or two to get it to full charge!
