50 % of range used up by on board tech!? does that mean that if I switch off the radio in my Model S I'll get ~600 km instead of ~300 km range?

- wyldfire 7y agoWell there's some tradeoff there but no, not that ratio. In general, yes, all of those features that are not the drivetrain still impact your range. Probably something like (mostly wild guesses here): Heater > AC > resistive-heat rear defrost > LCD/LED display(s) > bluetooth/LTE features > FM radio > headlights > wipers

- Wildgoose 7y agoPresumably this relates to everything from air-con to fancy maps displays using the GPS as well as the entertainment systems.
- ianai 7y agoIt’s the AC that eats up power.
- kwhitefoot 7y agoI think the maximum is about 6 kW in my Model S so if it were running flat out I think I would use about 25% more than if the climate control were switched off. My care typically uses between 180 and 220 Wh per kilometer, say 18 to 22 kW at 100 km/h.
- semi-extrinsic 7y agoFor autonomous, you're maybe running 2-4 kilowatts continuous load for the computing? At least no more than that? Then you have 2 kW for the air conditioning, probably 2 kW for cooling of the battery pack when running hard? Depends on whether you include those in onboard tech. Seems like the Model S does around 35 kWh/100 miles, at 50 mph that's 17 kW average power draw at highway speeds. If you're stuck in traffic, however, it's far less.
