... the five kilovolt battery pack ...
I did not realize that Toyota had a 5000 volt electric motor in their
vehicle! (I did not know that was possible.)
Or do electronics convert the 5000 volt electricity to some form of
pulses, down convert the voltage, and then enable a lower voltage
motor to run?
Also, how many joules does the battery pack contain when full?
What is its energy density compared to gasoline?
What prices of gasoline are equivalent to prices of electricity?
(I am told the `exact conversion' ratio is 36.36 kWh of electricity
per gallon of gasline but am not entirely sure. That presumes you can
get 130 megajoules per gallon of gasoline. Another source says that
gasoline contains 121 megajoules per gallon, which provides an `exact
conversion' ratio of 33.6 kWh of electricity per gallon of gasline.
(I just looked for my references and did not find any -- only
references of `the average price for Gazprom gas in 2004'.
(In any case, from the point of view of a driver, an `exact
conversion' ratio presumes the efficiencies of the two drive trains
are the same and they may not be. I am considering costs from the
point of view of the final buyer, not the efficiencies of converting
coal or what ever into electricity and of converting petroleum or
whatever into gasoline.
(Incidently at 121 megajoules per gallon, 30 miles/gallon of gasoline
is 400 meters/megajoule.
(When you know how many meters a car will move on 3.6 megajoules or 1
kwh of electricty and how many meters that same car will move on one
gallon of gasoline, it is easy to convert.)
Thus,
USD 0.10/kWh = ? per US gallon of gasoline
EUR 0.10/kWh (which is now around USD 0.14/kWh) = ? per liter
