I understand the cost to the end user is much less, but in what ways is their technology more advanced?

  How would that even be supplied? Megawatt circuits are the domain of industrial factories, not "gas" stations.

    The article states that it would need 650KW to charge at 6C rates. Huawei has already announced 600 kW DC fast chargers: https://asia.nikkei.com/Spotlight/Electric-cars-in-China/China-s-Huawei-launches-alliance-for-ultrafast-EV-charging https://asia.nikkei.com/Spotlight/Electric-cars-in-China/Chi...

      The bottleneck is the grid not terminal hardware. If a home or small business asks for a multiple MW circuit they're going to be laughed at for preposterousness. Laying harmless gigabit fiber to a new area requires permits, construction, labor, think of what becomes necessary when it's enough electrons to kill a dinosaur.

The UI is _miles_ ahead. And they are preparing to release a 1000 km (620 mile) range vehicle.

> in what ways is their technology more advanced? BYD's technology, not so much--they're better at manufacturing cars in degrees compared to Tesla, not an order of magnitude. The magic is at CATL and friends. There is a Cambrian explosion of battery technology in China that doesn't get reported super well in the mainstream press.

  What's going on with battery technology?

    Mostly cost reductions, there isn’t much room in the physics for higher energy density. Eg it will always be less than chemical energy density.

Adding to the other peer reasons, staggering range of design styles and price points; executive class, cheap fun young cars, utility vehicles, etc.
