Everyone's talking about charging infrastructure but the funny thing is that, for most people, keeping your EV charged wouldn't be a huge hassle. We're already used to plugging our cell phones in at night while we sleep. You don't actually need to plug your EV into a fast charger.

Let's say you get home from work around 7pm, usually, and you need to leave in the morning at 7am, so that's 12 hours of charging time per day, on average. Some days you might have less. But that's okay, because some days you might have more.

Now let's say you plug your EV into an outlet in your garage and have it draw power at the same rate as a space heater, so 2 KW. 12x2 = 24 KWH. The best EV's today get 4 miles per KWH, but let's go with a more average number of 3. 24 x 3 = 72. So in this scenario you would need to drive more than 72 miles per day to not be able to regain that electricity at night by charging your car.

Obviously this doesn't work for everyone. Not everyone has a garage, and some people drive more than 72 miles per day, but my point is that for a very large percentage of drivers, quite likely more than 50%, simply plugging your EV into an outlet when you get home would be enough to keep it charged and you wouldn't need any special infrastructure.

​

Now, if half the population starts drawing an extra 24 KWH per day that will put a strain on the power grid but that's another topic and a different problem.
