ICE cars don't need heat pump, there is plenty of waste heat generated from combustion process to be used to heat cabin etc.

@jellyd4889 not true at all.. cooling is superior in EV. Heating is superior with burning fuel. AC in ICE requires engine running to drive the compressor. ICE engine is only 35% efficient in converting energy in fuel to motion, wasting the rest in heat. That's why when you stand next to an ICE vehicle running AC, you feel more heat than cooling it generates. It's terrible. I often take nap in an EV running AC completely quiet no vibration in hot summer days. I can never fall asleep in an ICE vehicle running AC, it's loud, smelly, and vibrating. Hate it. Ideally, you'd want an EV that comes with propane or other fuel based heating system for cold weather, conserving battery for motion only which is 100% efficient.

@greghudson9717 I'm from Canada. Heating is far more important than cooling. AC is nice to have for a few days of summer, but if you don't have adequate heating in winter it's outright misearable or even life threatening. Currently, having an EV means sometimes you have to choose between range and have enough heat to stay comfortable.

@sergiomomesso1590 It depends how cold outside is. Heat pump loses efficiency below - 5, and consumption of electricity for heating becomes real drain as it gets colder outside, and becomes a serious concern of getting stranded if you don't have enough juice to drive to a charging station. A 1lb bottle of propane will last 5 - 6 hours of heating, no matter how cold outside is, it produces the same amount of heat from burning fire. That's way more robust than heat pump trying to extract heat from the environment when it's too cold outside. You said 22 C setting, but I doubt it will ever achieve it if it's too cold outside. Whereas, heat from buring fire can easily make you feel cozy warm, no matter how cold outside is, there is simply no comparison with lukewarm heat pump. Energy density of any fuel - propane, alcohol, kerosine, are about 20x that of average EV battery. Again, no comparison. And there is no waste in energy when burning fuel for heat, unlike trying to get motion out of it, it's only 30% efficient. Extracting heat from fuel is 100% efficient, no waste.

@sergiomomesso1590 So you are saying that you kept your car interior at 22C when it's -15C outside All night (I assume 8 hours at least), with only 5% of 74kwh, which 3.7 kwh of electricity? Sounds like science fiction to me... Maybe outside temperature was +5C and you keep interior at 22C then I believe you.
