How many times can you use the same gasoline? Once.
How many times can you drive the same ICE car? Probably
as many times as you can drive an EV.
How many times you have to charge an EV? Maybe
roughly about as many times as you have to fill up
an ICE car.
What is the efficiency of charging and running an EV by
comparison to an ICE car?
That really depends on the energy source. A Tesla
in China is likely charged by coal-generated electric
power. Here in Canada it could be electricity produced
from a natural gas-powered generator, nuclear power
plant or water hydro power.
Construction, maintenance and fueling an EV is
rather energy intensive. Manufacturing and production of
materials and metals required to build an EV is likely to be
more damaging to the environment than what is entailed
in building an ICE car. One thing is certain though, an EV
running on lithium battery is not as affordable to the less
affluent than an ICE car irrespective of its energy efficiency.
