Is your garage electric car ready?

Seems these cars can be charged with a regular 15 amp outlet, any 240 volt
outlet (50 amps best), or a 90 amp "4 hour charge" connection...

It's a 90A Circuit Breaker. However, the maximum current for the vehicle is
70A, as set by the duty cycle of the Pilot waveform.
At 240v that is 16.8 kw*4 to do a full charge, or 67.2 kw total. At the
national average of $.12 per kw that is about $8 ($.04/mile) for a full
charge to drive those 200 or so miles. This is about 1/3 the cost to drive
an average gas vehicle at 20 MPG and $2.60 per gallon.


And again, this is an example of comparing apples to oranges. These
electric vehicles are relatively small cars. And they should be
compared to similar size fuel efficient cars, not the average gas
vehicle. There are lots of car choices getting 30 city, 45 highway
or better. The Toyota Prius gets 51 city 48 highway giving a fuel
cost of about $12. Here in the northeast with electric at 17c kwh,
and using your above math, the fuel cost on the Prius vs the electric
is a wash here.

But I bet the Prius is a far more drivable vehicle, capable of higher
sustained highway speeds, etc. and doesn't have the obvious drawbacks
for the user that the electric car has.
