    It seems to me that I saw something in the old forum indicating the Aptera would be capable of V2G. Is that still the case?

    The version of the CCS charging standard that’s used in North America isn’t expected to include V2G capability until at least 2025. At present the only V2G system uses the ChaDeMo format.

    There is talk of some vehicles being able to output 110V AC current which would allow them to be used like small emergency generators for relatively light loads – but not for connection to the power grid.

      Are you sure about that? A few years ago CHARIN the agency that defines the CCS standard published a roadmap that said that V2G was scheduled for 2025 but the most recent version of the roadmap does not have dates on it. V2G is predicated on the communication specification which will actually come from ISO/IEC15118-20. My understanding is this is in release status 49.99 where 50 is released so it must be available to manufacturers. This must mean that all mechanical and electrical specification for V2G (or at least V2H) are fixed and it would only be a software issue to make a vehicle V2G capable.

      How many Watts surge and how many watts continuous? I was wondering if it could power a small 700W microwave oven.

    Not sure, but I sort of hope so. I want V2H (vehicle to home) and could care less about V2G. V2H is on the drawing board to be standardized long before V2G (though both are coming quickly). In fact, EV’s like the Ford F150 Lightening are introducing it in the spring of next year. But of course, it requires THEIR charger setup to make it happen correctly. I’m sure there is a lot of preliminary protocols floating around to interchangeability, but I wouldn’t count on that to work once the spec if finalized.

    V2H is much simpler, you control what happens on this side of the meter. V2G is a regulatory nightmare and I don’t really want to use my car to power someone else’s refrigerator and TV.

    So, somewhat available now, definitely next year. Can you use any bidirectional charger with any bidirectional car? Not officially yet.

    Will Aptera allow this? I hope so. Its the same CCS connector, a minor bit of hardware to allow bidirectional power flow and probably a couple of hundred hours of software time to make it work.

      I at least want something I can plug a freezer/aircon unit/ power tool into. There will be times that I won’t be driving enough to use all the power the panels collect, and there should be some way to consume the excess productively.

      I plan on using my aptera as a giant solar battery. Its peak solar input is 700w however thats at noontime on a sunny day. Going to cover a carport with solar panels tie that into the onboard solar charger and max out that 700w all day.

        I made a note during one of the Aptera calls. Steve mentioned that the solar inverter would be about 1,000 watts maybe 1,200 watts to account for the possibility of replacing the solar panels on the later with higher performing ones. I’d hope there would be an easy way to connect external solar panels easily to the car. So you could park in the garage or covered parking & still charge via the sun. I made a video about this and passed it to Aptera. They mentioned they passed it to the solar panel team. Fingers crossed.

    I hope they don’t waste anytime on this feature, they have so much to do and so little capital and staff to do it that a distraction like V2H could kill them. If you want backup for your house there are two better choices, a propane generator (I I have as 20KW Kohler) or solar panels and a power wall. My Kohler can power my house for almost a week with the two tanks that I have and if the outage goes longer I can have the tanks refilled. I got it after having two five day outages in a particularly bad winter several years ago. If you live in an area which gets a lot of sun then solar is a good solution, it will pay for itself eventually and it makes you independent of grid failures. I wouldn’t want to power my house from my car, I want to be able to go somewhere during a power outage and a drained battery makes that impossible. Also disconnecting the car to go somewhere will remove power from your furnace. It’s the lack of heat that makes power outages so uncomfortable.

      I do support laser focus on getting the car delivered. At the same time, I do like flexibility, but flexibility in things always leads to longer development times. At the same time, I’ve ordered the F150 Lightening to go with my Aptera mostly because of this feature (and at times, I need to do truck things)

      I do have a 20KW Generac whole house auto-start backup generator due to frequent power outages. Unfortunately, living among the trees eliminates the ability to use solar at all, not an option and since we live in a national forest, we are not allowed to cut down the trees.

      I’d like to see the feature available but it definitely does not need to be there day 1. Most people would probably never use it.

        I for one will be using the V2H features of the Aptera. It’s one of the main reasons I’m purchasing the car. V2G needs a power company ready to adopt that standard, and Idaho Power has shown no interest in V2G, although Idaho Power is a leader in renewable energy from non-residential sources. In the old website discussion list, someone claimed an engineer at Aptera told him/her V2H is in the cards, with a CCS connector, but I cannot confirm that. Every time I have a chance to submit that question for seminars, I ask, but no firm answers from a reliable source yet.

      Kind of late to the party on this one. I do agree V2H should not be a top priority. As someone who has solar panels and no battery, (I do get a 1 to 1 credit for every Kwh I put on the grid, so the grid is kind of a battery. Just one that does not work during a power outage and still charges me for delivery) I would like the feature to be available at some point fairly soon (1-2 years) after launch. I work from home and rarely go anywhere. If I could have my Aptera power my computer setup during an outage that we be great. If it could power two 15 amp and one 20 amp breaker that would be spectacular. For at least two reasons, No need to buy a separate house battery, and the battery will not be in my house just incase somethings goes wrong.

      <font face=”inherit”>I will still buy this car w/o that feature, as it is an amazing car. I do not want </font>adding<font face=”inherit”> that feature to the car to hurt the company.</font>

      There is wisdom in Joshua’s post.

      If it is in the plan fine (I don’t think it is) but if not, no effort should be made at this point to include it. There is only a very minor business case for including it..not a general demand for this feature as it would only apply to those that have or intend to have home solar. Trading that off for a potential schedule delay, parts sourcing in a difficult supply chain environment, and with uncertainty regarding the CCS standard is not a judicious decision. Then, of course, a price increase.

      Better to wait for Aptera 2.0 or a maybe a third party solution

      People don’t seem to understand the V2H is the killer application that will push many more buyers into the market. Especially here in Call where people have grid insecurity.

    The only thing close to V2G planned for the first Aptera is an AC inverter and power socket to give you 120 volt 60 Hz power from the Aptera. That’s no V2G; More of a V2H or V2X capability.

    As of a few months ago they were still researching inverter vendors and deciding on the specs. Don’t expect more than 1500 watts capability from their builtin inverter; the same as a standard household outlet. So you could power some tools or a fridge or a small microwave, or even charge another EV at Level 1.

      Harry, if the 1500W, 60H/120V inverter is still in the design, I think I could live with that, as long as the whole 60KWH (in my case) battery is available to that inverter. That amount of power could run my fireplace fan and refrigerator for days and days during a mid-winter power outage, my biggest concern. But I’d rather be able to use the V2H capabilities of the CCS connector, combined with a combo level 2 charging/V2H system such as the Dcbel so I could operate my central heat pump and air exchanger. Pulling the battery down no lower than 20% would still give me 4-5 days of power and keep the whole house warm. As long as I could manage without hot water and an electric stove or microwave, that’s dandy.

      A back up generator, or a solar array and battery bank that would accomplish the same task would approach $10K at a minimum.

        After 2 long lasting (many days) power outages here in NJ years ago, I finally shopped around for an emergency generator. You can buy a gas powered one for under $1000 that’s good for 7.5KW. I figured it cost over $1/KWH to run. Bought and installed my own transfer switch for a few hundred dollars to power my home’s critical circuits and I was good to go. Got it inspected to keep the town happy, too.

        I can now run my water pump, fridge, pellet stove, microwave, heat the outside bathroom to keep the pipes from freezing, so I’m good to go. Of course the power has never gone out once since then for over an hour or 2. ????

        All that is way less expensive than solar panels on your roof, but only good for rare emergencies. It is also much less expensive than a home battery storage system.

        If your utility allows it and pays you for any excess electricity your solar panels generate and you send to the grid through a grid-tie inverter, then ALL the electricity they generate will be used. That’s the most cost effective way to use your rooftop solar panels. Then charge all your EVs and run your home from the solar + grid power in your walls.

          Hey Harry, there’s only one lonely person shown on the NJ map. And that person also remembers that power outage, if it’s the one from the ice-storm you are referring to. And, of course there was Sandy. Won’t you join that person on the map as well? https://aptera.us/community/discussion/aptera-owners-map/ I’m sure there must be a few others from NJ as well.

            Hey Fanfare, NJ is bigger than you think. Look NW of you, North of Flemington near Clinton. That’s my practically next door neighbor, Steve and I, also in NJ. (Easton is on the eastern border of PA.) So that’s 3 of us NJ Aptera folk who have gone public.

      From the point of view of a utility customer V2H give 99% of the benefit of V2G so even a basic AC output is valuable. The virtue of a CCS connection is that it could integrate with smart EVSE that could use the vehicle battery as a peak shaving device to avoid expensive electricity on time of use rates. I am thinking that the CCS equipment may be programmable and when the new standard is promulgated it can have this functionality added. If the Aptera can charge via CCS then it has all the hardware to use the future CCS features.

        I second that. We have a Powerwall to round out the solar use most of the time. For me, to have the Aptera’s battery available for secondary backup and getting an even higher percentage of our household use covered by the solar stored in the Aptera’s battery would be a feature that would shape my decision on whether this vehicle will suit our needs. 1500 Watts would be better than nothing, but through the CCS connection I don’t see why, within reasonable state-of-charge constraints, the export maximum could not raised to the 4-10 kilowatt range.

    I would welcome a V2H feature in the Aptera. Anyone have any updates on whether this is planned for short term or relegated to version 2.0?

      If they can implement the dc return power per the ccs standard then v2g, v2h, or V2L should be possible with an external inverter. Adding excessive weight or equipment in the aptera for the 20-30% of owners that will use it isn’t useful.

        I think this is more relevant for the versions with big batteries. Given they are prioritizing 400, then 250 versions, perhaps this is a feature to consider for the 600 and 1000 since they come later.
