GM To Launch Vehicle-To-Home Tech Across All Ultium EVs By 2026

All-electric vehicles offer a wide variety of benefits, one of which is impressive energy storage capabilities. Now, in order to leverage that energy storage for other uses, GM has announced that it will offer vehicle-to-home (V2H) bidirectional charging technology across the Ultium-based EV portfolio. GM states that the new V2H tech will provide customers with greater control over their energy management, as well as greater energy independence.

A GM customer uses an app to manage vehicle charging.

Essentially, GM’s V2H technology enables energy transfer from the battery pack in an electric vehicle to “a properly equipped” home, providing electricity during peak demand to lower costs, as well as lowering the impact of a power outage.

“GM Energy’s growing ecosystem of energy management solutions will help accelerate GM’s vision of an all-electric future by further expanding access to even more benefits that EVs can offer,” said the vice president of GM Energy, Wade Sheffer. “By integrating V2H across our entire Ultium-based portfolio, we are making this groundbreaking technology available to more consumers, with benefits that extend well beyond the vehicle itself, and at broader scale than ever before.”

GM customers looking to leverage V2H technology can do so through GM Energy’s Ultium Home offerings, as well as the GM Energy Cloud software platform, the latter of which enables users to manage the transfer of energy between the home and connected GM Energy assets.

The full V2H tech rollout is expected by the 2026 model year. The first vehicles to offer the tech include the 2024 Chevy Silverado EV RST, the 2024 GMC Sierra EV Denali Edition 1, the 2024 Chevy Blazer EV, the 2024 Chevy Equinox EV, the 2024 Cadillac Lyriq, and the new Cadillac Escalade IQ. To note, the Cadillac Escalade IQ is set to debut tomorrow.

Further information on GM’s new V2H technology and specific rollout timing will be released at a later date.

    Is that the 2024 Lyriq or the 2025? My local dealer shows they have 8 2024 Lyriq’s and no mention of V2H.

      This is most likely just an upcoming software update to enable this and/or it may require you to have the 19.2 kW charger available in the 2024 Lyriq.

        If 19.2kWh charger is required they should state that now so that those of us ordering cars pop for the feature if they are interested in it down the road to activate and use.

    I’d guess a feature like this is something that will be offered as a subscription service. If you want the software to manage this, you will have to pay.

      Would never pay for this. Give me a vehicle I want to drive and enjoy doing so.

        I guess you’ve never been freezing for a week (yes a full week below 32 and no juice). If I’m going to pay 12 grand for a battery in a car, I want to be able to use it in a power failure for survival.

          I won’t pay 12 grand for a battery in a car.

            You did pay over 5 grand for the 12V battery in your present car.

              Huh? My last battery cost $129.

          Where I’m at, having a two or three-day outage on a yearly basis is typical. So every time that happens, all around the neighborhood folks drag out their portable stand-by generators and start them up. It beats not having water (since we are all on wells around here) but the nights are loud and annoying. So if GM is going to sell virtually everything with the capability to be a power bank that allegedly could power homes like mine and my neighbor’s for a week or more, I’m willing to check out that alternative. What gets me is the total nonsense that some folk just have to fabricate to try rather accept any of that. Yes, they flat-out make things up and slap themselves on their backs for being Pinnochio. I have no intent to go electric for a long-range vehicle. There isn’t a proper structure yet to support it. But as an around-town vehicle, as the prices continue to fall for EVs, they are already a viable alternative to a fossil-fueled vehicle. This feature is well worth considering when my current around town vehicle will be replaced.

        Whatever it requires in the way of equipment, get out your wallet, it is going to be $$$$$ if it is similar to the Ford system for the Lightening. I’ve read reports that it is between $5500 to $9000 depending upon the necessary wiring.

    A reminder that this is not just a simple update and you’re good to go. You need to install specialized hardware in the home to make this work (MSRP of this hardware not yet available). As mentioned by a previous GMA article, GM offers three variants:

    *Ultium Home V2H
    – GM PowerShift Charger
    — Enables bidirectional charging when paired with Ultium Home V2H Enablement Kit
    — Up to 19.2 kW AC charge speed
    – Ultium Home V2H Enablement Kit
    — Includes inverter, home hub and dark start battery
    — 9.6 kW of discharge

    *Ultium Home Energy System
    – GM PowerShift Charger
    – Ultium Home V2H Enablement Kit
    – GM PowerBank
    — This stationary storage unit can connect to V2H Enablement Kit to extend backup capability and store solar or grid energy
    — Available in 5 kW or 7 kW variants

    *Ultium Home Energy Storage
    – GM PowerBank
    – Inverter and home hub

    Wow, a likely very expensive option that very few people will actually use. First, power is not cheaper at night in my state and likely won’t be anywhere else once there are millions of EV’s charging at night. Second, we rarely have power outages and I already have a generator.

    GM just give me a 25amp 240v plug port on the vehicle to use and control its output. I’ll do the rest!

      The point is if you are already spending 10-20K on a battery in the car, then get more use out of it and not spend another 10+ K on a battery that is fixed to your home. I might be more inclined to have a battery specific to the home if it was not LiPo, and it was priced more like 10 bucks/kwh instead of 100+. Space is not an issue for a home battery, so go with cheaper formulations.

    Thinking utilities will have a significant safety concern about using the EV battery without disconnecting from the utility. They’re paying people to turn in portable generators because of fears that linemen will be zapped from improperly hooked up portables. Properly isolating each source will add $$$$ to the install.

    Yes, but years behind the Tesla approach : available on road charging, solar at home, battery backup at home, bi-directional home energy for emergencies. And they can furnish all the parts, well engineered, and dependable.

      I’m not sure about the on road charging. Tesla is the most American made car brand, don’t believe me look it up.

    Hummmm, I think GM worrying about this kind of thing is really premature:

    Item: Silverados, Colorados, and now LYRIQs are experiencing dead 12 volt batteries due to poorly written software upgrades. Since I refuse all updates (which is allowed to be refused on my 2023 LYRIQ) I don’t suffer from it.

    There IS a problem with the LYRIQ in that if you try to run an inverter from the official power take off points the 12 volt battery will go DEAD even with the car fully on. I don’t want GM to know about it since they’ll no doubt have a hastily written correction which will break more unrelated things… My perfectly acceptable work around is to turn on the rear window defogger and air conditioning which gets the car USED to charging the battery. Then my inverter can take power uneventfully.

    The problem that GM is unaware of is obviously due to the ‘engine control module/Load detector module’ installed in all the above vehicles. THE LDM is a silly, superfluous device since monitoring the battery voltage and outside temperature is enough to tell it whether or not the car’s 12 volt lead acid AGM battery needs charging.

    Meanwhile, for the first full year of the hummer ev had only 48 ampere rechargers available (in a vehicle which really needs it as it is a power piggy, plug the high $$$ price means there would be great desire for the unavailable 80 amp recharger.

    But there were no 80 amp chargers available since EVERY 2023 LYRIQ has an 80 ampere module STANDARD… Now, people are told ordering the 2024 LYRIQ that they must drop the 80 ampere option since all of them are going as options in the HUMMER EV, which should have been the arrangement in the first place, since only 1 or 2% of LYRIQ buyers would need any more than the standard 48 ampere unit. For the vast majority of customers for the LYRIQ, myself included even a smaller 32 amp unit would be perfectly adequate.

    Since they can’t get simple stuff working for existing customers on a remotely timely basis, you would think they would forget superfluous crap until they got the basic stuff working right.

      When it came out that the 19.2KW (80A) units were going into the DE Lyriqs, it was rumored that GM was doing that because they had ordered those in quantity for the Hummer and since the Hummer wasn’t selling that well, and they couldn’t get the 11.5 KW (48A) chargers for the Lyriq due to supply chain issues, they diverted the units they had to the Lyriq.

      It made sense at the time, but since they ended up releasing only a handful of Lyriqs in 2022 it didn’t matter too much.

    Electric utilities are reducing the financial benefits of solar. Under their latest Net Energy Metering agreements solar energy produced by the homeowner brings less and less benefit in offsetting the cost of power drawn off the grid. Adding a battery to your solar helps solve this problem, but batteries are expensive. I have a Powerwall system and yes it requires additional electrical equipment like additional service panels and the Tesla gateway but the Powerwall was by far the most expensive component. The GM Ultium V2G concept uses the battery that’s already in your car which is not only cheaper but a lot more useful as it has much more capacity than commercial solar storage batteries that are in the 10-16 kWh range.
