alt Hacker NewsWe should always take marketing number with a huge grain of salt, so the 10 to 98% in 7 minutes remain to be seen. Also, there is the question of if it lowers the battery lifespan faster than charging at lower power. It is does, there might still be a point in battery swap, especially for public transport systems (for bus). A public transit operator might want to have more battery than vehicle, so that they can rotate the battery regularly and charge them at lower power, to diminish and distribute the wear on battery. But that's obviously a big if and a more niche usage.

This kind of fast-as-possible charging rather than overnight or "while parked at the mall for hours" slow charging should be the exception rather than the rule, i.e. it is useful when road-tripping long-distance, but is not not the daily case. Battery lifespan should not be based on assuming that it's the only thing that you ever do.
the life span stat with the current battery tech is mostly useless for a normal car. 300 mile range most people will need to top up 2 times a week 100 times a year 1000 times in 10 years. The battery degradation is not that bad in the first place.
