He is explicitly claiming that the angled windshield will increase power consumption and shorten range. I think it's pretty clear that the opposite is true even in the worst case.
- simondotau 4y agoA larger but well insulated cab could have a lower A/C energy cost than a smaller but less well insulated cab. More air volume doesn't dramatically change the energy footprint when a stable temperature is being held for a long period of time. With sufficient insulation, the main consequence will be greater hysteresis, i.e. bringing the cab to temperature might consume more energy.
- modeless 4y agoWhat you say is true but I interpreted his complaint as being about the increased sunlight heating up the cab, rather than changes to insulation or air volume.
- faitswulff 4y agoIt will increase power consumption if you are using the AC to melt accumulated ice or snow.
- modeless 4y agoMelting 2" of accumulated snow from a 2m^2 area would take ~2 kWh which is roughly 1 mile of range or 0.2% of the battery, if my very approximate calculations are correct. Or, exactly 0 miles of range if you are plugged into a charger at the start of your journey. But I think the original thread is right that you'll need to manually clean ice and snow off the windshield which, unlike the AC thing, definitely seems like a legitimate complaint against sloped windshields (though I have no personal experience on this point).
