I doubt it.
The physical infrastructure required to do this at any scale makes it prohibitively expensive. I've rarely spent more than 15 minutes at a fast charger. Modern BEVs have a pretty impressive charging curve, and with the extensive charging network that is available, at least in Norway, you can optimize this further. I think there's a good analogy to IP over Avian Carriers. You can technically get super high bandwidth, but the latency kills you. Latency in this case being the physical battery swap stations.
Having swappable batteries on the other hand, that might have some benefit. I don't really need a 82kWh battery pack in my car for my every day needs. It just adds a lot of weight. I also think this is what Nio is aiming for. I doubt they see battery swapping as a solution to fast charging, more to let customers have some flexibility in terms of battery capacity, and to make people still nervous about battery longevity calm down a little.

Nio's deploying another 1,000 swap stations this year: https://cnevpost.com/2023/02/21/nio-plans-to-add-1000-swap-stations-in-2023/ https://cnevpost.com/2023/02/21/nio-plans-to-add-1000-swap-s...
- vegardx 4y agoThat's still just a drop in the ocean. Tesla alone has more than a thousand 150-250kW+ charging stalls in Norway alone, in over 100 locations. If you combine all other providers we're looking at more than 5000 stalls, providing 150-350kW. Nio is also deploying fast chargers alongside their battery swap stations, which leads me to believe that they also see the limitations with swap stations.
- clouddrover 4y ago> Nio is also deploying fast chargers alongside their battery swap stations Why would you think it's exclusively one or the other? It's never been exclusively swapping or charging. It's always been both swapping and charging. Nio's cars do both. Remember your claim was "the physical infrastructure required to do this at any scale makes it prohibitively expensive". That's plainly false. > Tesla alone has more than a thousand 150-250kW+ charging stalls in Norway alone Yes? And? So? What? Nios can charge at those Tesla charging stalls.
- vegardx 4y agoMy initial comment was to someone who believes that battery swapping will win out in the end, which I'm fairly certain it won't, just given how good fast charging technology is now. Reportedly Nio is burning cash at an unprecedented rate. I would assume the complexity of making the battery removable is digging into their margins quite heavily, as well as building out this infrastructure that very few actually needs. I see it mostly as a gimmick to get people who are hellbent on thinking that battery technology will either massively increase all of a sudden or those that think batteries degrade much faster and more than they actually do.
