If you're looking at fast charging (1 hour or less) on a regular basis, you're doing it wrong. The vast majority of charging should happen while the car is already parked, using level 2 AC charging. This means when you park at home, with, etc, you take just a few seconds to connect a charger, then walk away. When you come back ~8 hours later, you take a few seconds to unplug before leaving. This approach, believe it or not, means I spend less time dealing with fuel than if I had a gas car.

Plus, AC charging is much cheaper, and more reliable. These chargers are very simple devices, that just do a bit of monitoring and negotiation. They deliver raw 240v to the car, which has its own AC-DC converter.

DC fast charging is much more expensive - $14 for a full DC charge is very unlikely. That's because DCFC stations are very big, complex installations. As such, they also have parts fail on a regular basis. DCFC is often more expensive than gas, but again should only be used on rare occasions.

As for batteries failing, it's about as often as a gas engine fails. IOW, it's extremely rare until the car is EOL anyway. Battery degradation is typically 85-90% health remaining at 100k miles.
