Those chargers already exist. Tesla vehicles are limited by their 400v electrical system. Porsche already charges faster for longer via an 800v electrical system. You also have to remember even 10-80 throttles SIGNIFICANTLY over that window as the battery fills. The higher speeds will run for longer on a larger battery assuming it is designed with sufficient cooling - one of the features of solid state batteries is supposed to be the ability to charge at higher rates for longer duration.
