With such large battery sizes and range, consider providing a CCS/SAE port, which will be supporting the Vehicle-to-grid capability in incremental phases. https://insideevs.com/news/342354/charin-ccs-combo-standard-to-offer-v2g-by-2025/

Thanks for sharing your thoughts on this matte. Do you know any national PV Solar installers I could link up with to plan to enhance my home’s PV solar for ultimate bidirectional charging? We are in the Southwest and haven’t found one that is up on this.
I would love the V2G ability. I think 100kwh is a lot of battery to sit in your garage and it could make you some money while also providing plenty of transportation. Just make it easy to adjust so you always have plenty of range.
Currently V2G is a ChaDeMo-only thing: It's not part of the current CCS standard nor does it seem to be a Tesla "thing," either.
Have you heard of the million mile battery? The million mile battery makes no sense for a car because that would be about 45 To 75 years of ownership. But the million mile battery makes perfect sense for 3 to 5 cycles per day in a V2G world. V2G may not be here now, not even for Tesla, but it is most assuredly the future, especially for Tesla.
Will, thanks for pointing out the interesting V2G link.
Mark, you make a good point that a million mile battery is too much and overkill for a private car. It is also too much for a V2G feature. My understanding is that a Tesla EV with a million mile battery would be just the needed lifetime for Tesla's vision of an AI driven taxi fleet.
Taxis are going all the time and some do well over a million miles in their lifetime. A Prius taxi in Toronto was famous for going 1,000,000 miles on its hybrid battery, proving its long life. (But the gas engine did most of the work.)
My understanding is that V2G EV batteries would just be used lightly in the middle of their charging range, where the batteries would not be stressed. Once EVs and V2G chargers are ubiquitous, only a small fraction of each EV's battery energy would be more than enough to stabilize the grid during peak loads.
Chevy Volt and other EV's have after market inverters available to use for camping or backup home power when the grid is down. Not sure if that will be an option or standard on the Aptera.
I don't want Aptera to wait until 2025 for the system standard for V2G is worked out. Now it is just a feasibility study and set of experiments run by a few universities and utility companies.
The million mile metric obscurate the actual performance data of the battery. It doesn't factor in time based ageing of the chemical cell, battery cycling improvements vs battery capacity improvements vs battery cost reduction contributing to the outcome, depth of discharge, percentage capacity remaining at EOL. We should also recognise that the million mile metric is likely a result of mathematical modelling and not some Tesla mule that has driven around the world ~40 times. We will learn more in September. The best outcome would be a battery with very low cost cycling make V2G sensible and electric cars economically the only choice. Exciting times.
