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?

yeah, it’s mostly because EV’s are so efficient when they’re efficient. but a lot of things can make them inefficient. whereas ICEV’s aren’t all that efficient to begin with, so there’s not a whole lot of things to make them even more inefficient. a lot of the ratings of EV’s might be under “too good to be practical conditions”. ie a 10% drop on efficiency for something running at 80% efficiency is way larger than a 10% drop on something running on 40% efficiency.

Think of an EV as a greyhound and an ICEV as a sturdy Labrador. Both are dogs (vehicles), but they have different strengths and weaknesses due to their unique builds and characteristics.
Greyhounds (EVs) are built for speed and efficiency but can be more sensitive to factors like temperature, terrain, and overall conditions. Their lean bodies and thin fur (battery and energy systems) make them more susceptible to cold temperatures, which can slow them down or tire them out more quickly. Similarly, EVs can lose more range under certain conditions because their batteries and systems are more sensitive to factors like incline, air resistance, and road conditions.
Labradors (ICEVs), on the other hand, are more robust and adaptable to various conditions. Their stocky bodies and thick fur (engine and fuel systems) provide more resilience against factors like temperature and terrain. While ICEVs can still be affected by conditions like incline, air resistance, and road conditions, their engines and fuel systems are generally less sensitive to these factors, meaning they don’t lose as much range as EVs might under similar conditions.
So, EVs are like greyhounds, more sensitive to conditions that can affect their efficiency, while ICEVs are like Labradors, more robust and less sensitive to changes in their environment.

Battery temperature or the need for cabin heating do have a noticeable impact on a BEV’s range. The ICE’s inefficiency just makes heat available at no additional cost, which makes it able to run at more or less the same temperature condition year-round once it’s warmed up.
The other factors you explicitly mention don’t generally affect EV’s more than combustion engines. Incline, tires, air resistance and road conditions do affect the energy needed to push a vehicle forward, regardless of the propulsion system used. If a given situation needs twice the power from the engine, at a given efficiency the engine will need twice the input (electric or fuel). With an EV the efficiency doesn’t vary too much depending on the torque output and rpm, while in a combustion engine the variations are much larger.
So, for a climb in an EV, the additional battery consumption compared to a flat road will roughly reflect the increased power needed to push the car uphill. In an ICE you could see a relatively speaking lower increase in consumption than on the EV, in case the test speed and the given incline put the engine in a more efficient operating point. But the opposite could also happen, where let’s say the ICE has a 30% increase in consumption, the EV only 20%. Depends on the combustion engine, the tested speed and the incline.
What could make heavy workloads more noticeable on EV’s is that ICE’s tend to be more efficient at around peak torque, while EV’s are already efficient while cruising at 30 mph, so you’ll notice the full additional workload on the consumption.

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.
