Mustang Mach-E Home Charging

A friend's wife is buying a Mustang Mach-E and is talking about adding the home charger on a 60 amp circuit. When I look at their numbers for charging time, they seem to exceed the capacity of the battery. I suppose that is taking into account the inefficiency of the charging process? The web page says 15 hours at 32 amps on 240V so 7.7 kW and 115 kWh into a 91 or 97 kWh battery (not sure why they have two numbers for the same car). Is the difference in kWh between the battery capacity and the charging energy due to charging losses?

Using the direct wired EVSE the numbers are 240V at 48 amps for 11.5 kW and 10.9 hours for 126 kWh. Even less efficient!

Aouch, EV6 with Meridian audio system then, Guiness World record Level 3 charging performance too.

Charging losses are usually around 10%. My guess is that Ford is purposefully overstating how long it will take to charge, so that they don't get any complaints from customers. It's likely to finish before the stated times.

If an EV's charging to 100% there's a point at the top where it slows down drastically while it's balancing the cells so that added time may be factored in there.

Any idea why they publish two sets of times? I can't find the other set at the moment, but the kWh amount was closer to 100 and I think it referred to EPA testing.
