“If you can’t charge at home, forget it.”
I’m sure you’ll still be able to charge at home, but it would take a hell of a lot longer than 9 minutes - more like many hours.
You figure that for it to go 600 miles it has to store about 150KWh. with a 240, 50amp home charger it would take about 12 hours for a complete charge. and cost you around $60 in California at the current electric rate (less in most other states). Which really isn’t bad, and unless you’re going on a long trip, you don’t need a full charge - a couple hundred miles a day would more than suffice, which would take only a couple of hours of charging time at home.
As far as I’m concerned the most important spec for a battery is charging time. Range is secondary. I’d be perfectly happy with a 5-10 minute charging time and a 300miles range. On long trip I usually stop every 150 miles anyways for bathroom breaks and just to rest a bit.
Your post makes sense and a lot of good loints. I still believe the only electric car I would consider is a gas/electric hybrid with indefinite range and a cheaper to replace battery. Putting at least 3/4 of electric vehicles as gas electric hybrids and put better and better batteries in them AND enough fuel capacity to Exceed most or all current gas only vehicles and you would end range anxiety and sell many more than currently.
