first and fore most i feel electric cars are made all wrong
i believe that the cheapest way to said route is to not build a new car
replacing engines and transmissions from existing cars is more ecological
removes a ton of weight
plus provides more choice to the end user
asking people to change is hard
so i would rather not change anything from the end user prospective
informing people of their battery level seems like one more thing to worry about
said the charging o f the battery should be automatic
not something that they have to think about
the battery charger will gain power from these sources
brakes
small generator
2 ac wench motors
those motors will be directly powered by a capacitor
which will be connected to a battery controller
which is hooked up to a battery charger
then one cheap battery up front
and a expensive in the back
giving even weight distribution
this pyramid of power should allow for a car
that rarely if ever uses gas but has it more as a fail safe
not a range extended bullshit
also because you shed about 500 to 1000 pounds of the car
spread the weight evenly
it should handle better
and be faster with more torque
and this the cheapest configuration
you could turbo your generator so you could blast threw most of your power
and still charge it while running it
because you could split power and send power to your capacitors
while your charging the battery
so you save your battery from the flicted charging cycle
