    “and claims a charging rate of up to 11 kW and with an efficiency of about 90% for easy overnight charging.”

    That’s a some 9kW lost on a 80kW battery. I get the convenience, but I think the best use for those would be when standardized and installed in public parking spots, for a brief charge bump, not to charge fully at home, e.g overnight, which is what Porsche aims for.

      Using the right units is important.

            High-schools probably also spend about 52 mins explaining integrals...
