It also matters who has heat pumps and who doesn’t. Keeping the meat bags warm is a lot of energy.

- jeffrallen 4y agoThe heat pump is for the batteries. If there's some heating/cooling left over, it's for the meatbags.
- brianwawok 4y agoI don’t think many people are driving around in winter with a 30 degree cabin temp. IME meat bags get priority at all times except while supercharging, when the temp can go pretty wild while it focuses on the battery.
- jeffrallen 4y agoI drive a Renault Zoe which has a heat pump and air-cooled batteries, and I can tell you that the Renault engineers were very protective of the battery. I've never had a problem with the cabin temperature, but it's clear that the HVAC system is sized and optimised for the batteries. For example, when charging cold batteries, the blower revs up much higher than it would ever go for the cabin.
- galangalalgol 4y agoLooking back into the source article some of the more better performers do actually have heat pumps. It seems one of the mistakes is that some of them do not start heating the batter in advance, while others spendnpower to keep it warm while plugged in.
