When they start selling cars only powered by batteries I'm going to
invest in a tow truck business.

The time has arrived:

And a good place to base the new tow truck business is about half way
between SF and LA, because that's about how far this $100,000 car will
take
you.

Scroll to the bottom of the page.

Or half way between LA and Vegas.

The page leads to some "interesting" information.

If you cruise around you find claims that the energy usage is 110 Wh/km,
and recharge time of about 3.5 hours.

110 Wh/km is about 11.7 kWh for a 100 mile trip.

If the charging process is 100% efficient (not in this universe), to
recharge in 3.5 hours requires 11.7/3.5, or about 3.3 kW.

At 120 V, that's 27.5 A, which is a bit beyond the standard 15 A outlet.

At 220 V, that's about 15 A, so you better have a 220 outlet nearby.

Elsewhere they talk about recharging in 2 hours with some 70 A system.

Anyone out there got a 70 A plus safety factor outlet in their house?


Well, I just put in a dedicated 50 A receptable for charging electric cars.
Now, I just need the electric car.
