    Never understood why EVs aren’t made with standardized hot swappable cells. Would solve the range problem and the wear problem.

      There was at least one company several years ago that was trying. Go to a place and pay a fee, kind of like how you’d swap out a propane gas bbq grill tank. They’d forklift out the empty batt and forklift in the charged one, was their game plan.

      The tech is all too knew for standardization. Too many chemistries and voltages and places to figure out where to stick batteries.

      If what catl is producing right now is correct and true, we should be all set in the coming future. Supposed sodium batteries at 175wh per kilogram and over 10,000 charge cycles and very fast charging. Great for sub 300 mile range small econo vehicles. Then the solid state lithiums they’re working on are also supposed to have a high amount of charge cycles and energy densities close to 500wh\kg, which will give plenty of range and make the cars lighter, which is really needed to ease up on suspension and efficiency and tread wear.
