This is one of the huge overlooked advantages of electric cars, provided that the manufacturer added the feature (it's insane that some don't) you can straight up power your house for DAYS on the car battery.

I don't think you can power a home air conditioner for days on a teslas battery bank. It's the most energy draining system by far.

if we assume the lowest capacity tesla model S and a beefy AC that consumes 5 kWh/h, that's still 15 hours of non-stop balls to the wall AC usage.

Also, provided that you live close enough to a charger that is functonal, you have the ability to drive there, charge your car, and use the energy at home. That's probably less efficient and definitely more of a hassle than just having a backup generator and some dunks of fuel, but hey it's nice to have extra options.

5 kWh/h That's just 5 kW :)

Yeah, neither one of our electric cars will do that.

Yea I think that's just the Lightning. Cool idea but I don't see all the F150 owners switching to electric until they're forced to, at least here in the US.

Which manufacturers do add this feature?

[–] kudusch@discuss.tchncs.de 3 points 1 year ago

There are models from Hyundai, Kia, Nissan, Ford and Mitsubishi that can do bidirectional charging. Here's a video by the aforementioned Technology Connections on the Hyundai Ioniq 5: A 24-hour test run of the Hyundai Ioniq 5's Vehicle-to-Load function - Technology Connextras
