Long charging times are not a technical problem with EVs.

You didn't say the above? Long charging times are not a function of battery replacement, they are a function of the technical problems with charging batteries...

If you really care, I suggest you go to my post history on this thread and follow the back and forth conversation.

But to summarize yet again...

Long charging times are not a technical problem with EVs, they are a technical problem of EVs with built in batteries. If we want to solve that problem, it is solvable with current technology by swapping out battery packs although the EVs would have to be designed for that (some already exist) and some infrastructure would have to be built to accommodate it. However, it would not require any new battery technology or frankly any technology that doesn’t exist today. Ergo, it’s not a technical problem. If we collectively were serious about addressing that particular problem, then it would likely require standardization, some sort of lease financing or service subscription to cover the pack cost and a network of swapping stations, most likely along major interstates. Would that be easy? I didn’t say it would. Keep in mind battery pack swapping would only be necessary for long distances. Most people currently using EVs would chug along happily with their current pack, charging nightly and commuting to their office and the grocery store, until maybe it was time to visit Grandma out of state. It is doable today with enough money, cooperation and will. Or we could wait for another generation of batteries that might solve this problem someday.

Absent that, then yes, if you only consider EVs with built in battery packs as the only EVs possible to build, and with then assuming current battery technology, then long charging times are inevitably a hard-stop problem for people who need to travel long distances. It’s not a problem for people who live in cities and just commute and have time to charge at night, ergo the current EV marketplace composed almost exclusively of vehicles with built in batteries and which can’t be used for long range trips.

As long as we have gasoline and diesel powered vehicles, it’s unlikely we’ll ever have battery pack swapping on a large scale. The economics won’t make sense. EVs will have their metropolitan niche and everyone else will happily use ICEs. Instead of renting expensive battery packs, people with EVs will just rent even more expensive entire gasoline powered vehicles for those trips outside their EV’s range.
