Tesla Model S - Camper Mode

Teslas have very big battery packs, even the early models, so many owners already figured out that they can run the AC or heater non stop for a very long time. The only problem was that the software didn't allow it, so they had to find creative ways to trick the car to keep climate control on for an entire night's sleep, like opening the door a few millimeters, so the car stays active, using third party software to hook into the API ...etc.

A few months ago Tesla finally released a new software update, which allows you to keep the climate control on, as long as the battery has at least 20% charge left. For a fully charged 75kW battery this means 48+ hours of AC or 24+ hours of resistive heating. Yepp, you read it correctly, all Teslas to date use a resistive heater for heating the cabin and batteries. The AC compressor is only used for cooling, unfortunately. It would be a smart move to use it for heating too, as it has a much higher efficiency (98% resistive vs. 300% compressor).

I don't know what kind of bed they used in the video above, but there are at least a couple of companies, which make foldable/inflatable mattresses for Teslas' every seat configuration.
