Eli5: why does it seem that EVs’ efficiencies are much more sensitive that ICEV?

347 views

Besides the obvious cold temperature that affect the batteries, it seems that everything else (incline, tires, air resistance, road conditions, etc) affect EVs disproportionately? Never heard of an ICEV loosing 50% range on a full tank because of bad conditions?

Things like heating are a simple one.

ICE vehicles use the heat of the engine and just pump air into the car from near the hot engine.

Electric vehicles actually have to heat your car like a space heater would heat a room. So it’s electric that wouldn’t normally be used while a gas powered car is using the wasted energy it made just by running.

Both EV and ICE cars waste about the same amount of energy on common things like air resistance and tire rolling friction.

However, internal combustion engine also loses majority of its input energy as heat waste. That’s why ICE cars have huge radiators up front. All that burned fuel generates a lot of heat, but that heat is not helping move the car.

EV motors don’t generate that much heat, and most of the energy goes into moving the car.

If you chart the energy losses as a pie chart, in an ICE the engine the waste heat takes most of the pie, so other factors seem insignificant in comparison.

In an the EV the heat waste part of the pie chart is small, so other factors are relatively more significant.
