Let us imagine… (my bucket list)
I have a PV Solar electric system with DC power inverter, which is capable to divert power to storage batteries, but have not yet invested in the merging technology.
Imagine being able to store some or excess electric power generated by a PV Solar system into the Aptera’s huge battery pack, which could be tapped into in an emergency if electric power goes out?!
Present battery storage systems for PV Solar systems, depending storage capacity, could be well over ten thousand dollars… Having the huge Aptera battery packs “invested in and sitting in the garage” that could store this power and could be tapped “if needed” would be huge….
I.e., Another feather in the wingless flight vehicle’s (Aptera) hat!
Complementing Aptera’s attributes/offerings
Cost effective solution/option for existing and future PV Solar system owner who want to store power for emergency use. Cleaner emergency power option over a gas powered emergency generator.
I would like to be able to connect the car to my Airstream Interstate Camper Van. I have a 400 Amp Hour lithium iron phosphate battery in the van. I would tow the car on a trailer behind the van and have solar panels on both.
There are two questions:
Will Aptera enable bidirectional charger use, making the car a battery bank for home/emergency use?
Will Aptera participate in Vehicle to Grid (V2G) access development? That's further off than being able to connect your PV system to your Aptera EV, or using your Aptera batteries to power your home or your power tools.
Hello Aptera, will bidirectional charging be a feature in the first production models?
Only a few utilities and universities are currently running experiments to test how V2G would work. Other countries are way ahead of the US in this. So V2G may be many years away. Electric city busses and fleet vehicles will probably be part of such a program long before private cars.
Private use for homes (V2H) is still doable using the same equipment used to tie solar batteries to home systems.
Keeping the power draw low and the battery percent charge in its midrange would minimize wear on the battery. Battery degradation should not even be measurable if done correctly, and generously compensated if it does occur.
Not too early to discuss how V2G should work from the vehicle owner's point of view, however.
You would sign a mutually agreeable contract with your utility to provide some limited power during peak use periods in exchange for a good rate and reduced electricity rates during other times.
YOU would limit how much your vehicle provides and when, and the utility would guarantee that you had enough time to recharge fully by morning. A guarantee against battery degradation should be part of the contract.
I'm trying to see what the EV owner gets out of Vehicle to Grid for the extra charge cycles on his battery. How is the owner compensated? I can see Vehicle to Home to help cope with grid outages, but allowing the utility to burrow the energy I charged the car with has to result in more than a warm fuzzy feeling of helping the grid and environment out.

If they figure out a 1 million mile battery* @ 20% degradation and license it out, renewable energy uptake will skyrocket. Right now tesla power walls are for rich idealists.
A few years ago Tesla did the math and didn't find it economic. Cycling the battery has a deterioration cost. Investing in electrical hardware that will allow reverse power flow for emergency situations is not economic (infrequent use case) for mass consumer adoption.
Eventually car battery cycle cost will be sufficiently low that they will be part of microgrid infrastructure. This will be driven by economics.
Marketing the aptera as having this function could be beneficial to the brand even if it doesn't make sense for most users.
The newest charging port standard, CHAdeMO 3.0, includes grid charging capability. One would assume the Aptera will use the latest standard, yes?
Yes V2G V2H Vehicle to GRID and Home is starting up in many places. EVen Nissan sells a V2H LEAF option but only in Japan so far. The University Of Delaware has been doing a demo for 10 years now on the ACPropulsion MIMI-E Mini Cooper Electric that started BMW into Electrics. Most others like Tesla don't want to open the car as storage and Power use. They sell you a Power Wall for the home with the same battery cells used in their model 3, the 2170 cell. I made a website on it wwww.V2G-101.webs.com
What you are referring to is essentially V2G (ISO 15118), at least in part. There is also an advanced V2G effort focusing on renewables gearing up; https://www.greencarcongress.com/2019/11/20191111-bcm.html
