Yes, I agree, I think quick change battery packs were talked about 20+ years ago and discarded as impractical just in the logistics and time it would take to do it, nothing "quick" about it, lol
Not to mention how many battery packs you would have to have on hand at a "filling station", remember each battery pack would take 6-8 hours to recharge, so you swap one out and its no good for 6-8 hours
Talk about "energy shortage" line ups at "stations" between LA and Vegas, lol, they would be LONG
People are already use to say a 10min "fill up" so that's probably what to shoot for in electric vehicles
Plugging in at home or at work for a slow charge is not a deal breaker in my opinion, not having to change the oil, spark plugs and filters more than makes up for the simple act of plugging in an electrical cord, and many in northern climates have to do that all winter in any case, lol
But having the option for a fast charge, in 10min, would be a real benefit to get more people into electric vehicles
I like the idea of the supercapacitors as "part" of the charging system, they can take a fast charge without issues, i.e. no memory, and they can slow charge the battery pack if vehicle is parked after "filling up" or power can be used to extend range
Specific use vehicles have specific needs so saying "well they can't go 300miles back into the bush" is a non-starter in my opinion
My Ranger can't haul a 10,000pound trailer up the Grapevine either, but I still bought it and enjoy driving it
Despite this shortcoming
