Its also a terrible way of reducing charging time for anything that doesn't have an enormous battery like an electric Lorry/Semi. Even then its like 30 minutes for 70% charge for the Tesla Semi, which is roughly the same as a mandated break anyway for the driver.

What is more useful is making sure all EV batteries are easily swappable by third parties as this will massively extend the lifespan of EVs if you do not need to go back to the main dealer for a much marked up battery replacement when the cars battery stops holding a useful amount of charge past the 10 year mark.
