I just gotta point out one detail that I suspect is a minor error:

You're implying that you aren't factoring in the energy cost of the
refining and transportation of gasoline.
Three times 18% is 54%. You're saying that the complete power cycle
of an electric car is three times as efficient as the internal power
cycle of a standard IC engine car, or 54% efficient. However, you
also say that the internal power cycle of an electric car is only 45%
efficient. This implies that the efficiency of the electric power
plant, transmission system, and battery charging system (or
equivalent) is rather in excess of 100%.
