Preparedness vs. efficiency is almost always a trade-off. | |

| Jan 11, 2022 at 23:22 | comment | added | Highly Irregular | Though I don't have specific expertise or evidence to add weight to my comment, I have my doubts that a heat pump in an EV could even keep operating for long when parked in deep snow, and even if it could I doubt it could achieve COP 2.5. | |

| Jan 7, 2022 at 3:36 | comment | added | Fred | This all makes me wonder, maybe Toyota might be correct in favoring the development of hydrogen powered cars, instead of battery powered ones. Each form of technology for cars has it set of advantages & disadvantages. Charging a battery to 90 or 95 % capacity during cold weather will be another thing motorists will have to learn & adapt to. It might be preferable if car manufacturing had a system that altered the max charging capacity based on average air temperature in the previous 15 to 30 minutes before arriving at a charging station. | |
