There is nothing fundamentally different with that Merc are doing compared to others, there is no secret sauce here. Other cars can already recharge to 80% in 22 minutes and high power chargers are already widely deployed where they are needed.if you are getting similar filling times to ICE stations with high charge power over a larger soc window, thanks to 800v plus merc 'smarts' on micro-management of individual battery cells,
you can think I'm paying the same fuel rate as ICE with no downside, but practically these high power chargers won't be deployed widely for a while.
(I thought charging curve on 400v e-trons was also meant to be good but haven't understood if there is a compromise, like cell life, somewhere, or just good cooling ???)
e: think they said their catl cells inherently will have 6/8C charge rate capability
Is there enough of them to enable 30 million cars to become EV's today? No of course not but there is more than enough for the current number of EV's on the roads, part of the reason pricing is high is because of the relatively low utilization. If anything what we lack is low power chargers at key locations like hotels, the more of those there are, the less people need to use high power chargers.
