The Nissan leaf for example is available with a 75kWh battery. I assume the available capacity is less due to wear leveling and avoiding full 100% charge levels. Every mile driven consumes about 290Wh in a Leaf, in normal conditions without heating and obeying speed limits.
The universal EV charging cord is 12 Amps 110 Volts, so 1320 Watts. To charge 50kWh of capacity (172 Leaf miles) it would take 39.9 hours at 95% efficiency. People often say that charging this was is 3 to 4 miles per hour. Charging 12 hours each night gives you 48 miles. Enough to get to work and back for most people.
A NEMA 5-20 plug should be available for an EV. It has a prong that is perpendicular to the other. They are rare, and usually found on large 20 Amp 110 Volt air compressors or commercial equipment. This lets you switch in NEMA 5-20 outlet that you often see in commercial buildings in your garage, as long as you already have a 20 Amp circuit, which you should. They are rated for 16 Amps of continuous draw, while the standard 5-15 is rated for 12 Amps continuous. 108 Volts at 16 Amps is 1733 Watts. Now you can charge 50kW in in 29.4 hours. This method takes $4 in materials, and 20 minutes to install. The NEMA 5-20 charger cord would cost extra.
Every EV that I know of will charge on 240 Volts using the universal wall charger. You just need cut the plug off and put on a 6-15 plug on the EV charger cord, then make an adapter with a 6-15 receptacle to 5-15 plug which you will use if you need to charge from a 120 Volt outlet. You can rewire a garage circuit for 240 and replace the outlets with NEMA 6-20. 225 Volts at 12 Amps is 2700 Watts. With this you can charge 50kW in 19.5 hours. If you use the 16 Amp version you can get about 33% more. This modifying an existing circuit method would take 3 hours, about $40 in materials, and is easy to do. Your breaker panel will need an empty spot for a breaker.
More advanced methods involve using 30 Amp electric dryer and 50 Amp range outlets.
