The smaller battery offered on an E-Mustang is 68kWh, the larger battery offered on the F150 is 130kWh. A typical level 2 charger for a home installation draws 40A at 240V, and so delivers 9.6kW to your car. Level 2 chargers are available to twice that size if your home has a service that can support one.
In any case, assuming a typical charge cycle of 80%, your 40A level 2 is going to take 9 hrs to put an 80% charge into a 100 kWh car battery.
A single lithium ion battery operates at about 4V. The car's drive train runs at ~400V and that will be likely be going up, so you have have multiple blocks of more than 100 cells in series in the vehicle.
