The thing that concerns me most about battery swapping, is what happens over time? After 90,000 miles does whatever holds the battery in place still hold it as securely? Is there a possibility of a swapped battery skidding down the road underneath the now coasting car? Afterall, we are very aware of the reputation Chinese manufacturing has.
I ook at China as producing both sh!t and good to excellent quality on par with the western world. When you look at european brands ranging from quality to crap toaster’s to coffee machine’s, TV’s to cars, battery cells etc choosing China as a manufacturing/production base, all can’t be that bad with the better quality stuff. For years TCL made LCD screens for Samsung, Volvo’s EX30 and Smart #1 are built in Zeekr factory on Zeekr’s platform. BMW ix3, Citreon C5x, Cupra Taviscan, Dacia Spring are all made in China and shipped back to europe
Back to the subject, as long as the correct torque is used when replacing the batteries, I see no long term problems.
