I would trade battery capacity for faster recharge times. I think the engineers are not attacking the correct problem. If could only go 100 miles between charges but I could recharge in 5 minutes then that would be ok with me. The 6-8 hour recharge is BS I don’t care how far you can go.
That's an excellent point. Daily commuting could be done on a single charge. If longer trips could be accomplished with a rest break every hour or so on the road that might be a good selling point. But the rest break would have to be reasonable and not significantly impact the total trip time. Stopping for 5, even 10 minutes to recharge the car and discharge the bladder is reasonable. Having to kill and hour to charge for another hour's drive is not.
The kinds of duty cycles you're talking about are probably getting close. That kind of capability (and reasonable initial cost and cost per mile) would make me look at an EV.
Don’t forget that batteries lose storage capacity with each recharge.
