GM final week introduced particulars relating to its vehicle-to-home (V2H) system, set to launch with the Chevrolet Silverado EV RST, that may assist EV homeowners again up their residence with out the assistance of a storage battery like a Tesla Powerwall or a backup generator.
It’s in the end a part of GM’s large vitality play that sees EVs turning into residence energy banks and extra. Vans just like the Silverado EV are actually enormous cellular battery packs, with this truck’s large 205-kwh capability the equal of 15 Powerwalls; even making a small portion of the pack obtainable ought to be sufficient to energy an American residence for days.
In accordance with GM the V2H bundle will initially solely be obtainable for buy in California, Florida, Michigan, New York, and Texas.
“We’re carefully monitoring curiosity in different states and laser targeted on delivering an unparalleled expertise for our prospects, and we can share extra concerning the availability of the merchandise all through the U.S. in future updates,” GM spokesperson Sanaz Marbley stated to Inexperienced Automotive Experiences.
GM Vitality app
The automaker has a much bigger imaginative and prescient for the product. GM as soon as once more famous with the announcement that it plans to develop V2H bidirectional charging know-how throughout all its Ultium-based EVs by mannequin 12 months 2026. It confirmed that the 2024 GMC Sierra EV Denali Version 1, 2024 Chevrolet Blazer EV, 2024 Chevrolet Equinox EV, 2024 Cadillac Lyriq, and the long run Cadillac Escalade IQ can even be a part of that rollout. It is extra just lately clarified that these merchandise will not be walled off to a GM Vitality app, as beforehand envisioned (pictured above) however as an alternative as a part of their respective model apps—for Chevy, GMC, or Cadillac, as an example.
Within the case of the Chevy Blazer EV, GM has already confirmed that fashions delivered from the beginning have all of the {hardware} wanted for compatibility with these GM Vitality elements, however the software program to make use of it gained’t be in place till someday later within the 12 months.

Batteries included, different {hardware} wanted
The GM Vitality Powershift Charger that’s initially necessary to entry the autos’ bidirectional performance will value $1,699. It’s good for charging at 19.2 kw AC, whereas discharge energy from the unit is DC and peaks at 9.6 kw.
The opposite crucial piece, the V2H Enablement Package, prices $5,600 and consists of an inverter, a grid disconnect change, and the 12-volt dark-start battery crucial to maneuver the contactors within the case of an influence outage. That brings the whole element value to $7,299.
For individuals who need all of it on the GM ecosystem, GM Vitality stationary vitality storage and photo voltaic integration will each even be obtainable for buy beginning later this 12 months.
GM cautions that set up prices for the gear are primarily based on plenty of components, together with the place you reside, the age of your private home and electrical panel, the situation of the panel, and your servicing electrical utility.

Chevy V2H: Like Ford, go away hundreds for set up
GM is not at all first-on-market with this performance, because the Ford House Integration System has already been obtainable for practically two years. Working with the Cost Station Professional, which is already included with large-pack variations of the F-150 Lightning, it consists of {hardware} that carry out those self same roles, permitting homeowners to make use of vitality from their truck to again up the house. Tesla can be providing a Powershare function with the Cybertruck—allowing 11.5 kw of residence backup energy by the cost port and claiming no extra gear can be wanted for houses already outfitted with a Powerwall and its Wall Connector. Tesla factors to a typical set up value of $2,000 to $3,500 excluding the price of the gear, which might at minimal be an $1,800 Gateway along with a appropriate wall connector.
Ford’s set up of the house system depends on photo voltaic supplier SunRun. A web page from SunRun that seems to have been up to date for the reason that unique launch, now says the system prices $8,900 to $9,400 to put in together with the Ford Cost Station Professional, which can be a redundant piece. Ford initially advised Inexperienced Automotive Experiences {that a} best-case-scenario set up—not requiring a brand new panel or service improve—would value about $6,000, together with the {hardware}. Ford hasn’t responded about up to date set up prices for the system, and primarily based on different experiences and suggestions from homeowners, it’s prone to value hundreds extra for a lot of households.
EV residence backup and the shift to Tesla NACS
The opposite large query that’s been left unanswered by GM is whether or not this method can be forward-compatible with different EVs, by way of an adapter, after GM switches to the Tesla-based NACS connector. As NACS has been standardized, it does assist V2X applied sciences, so whereas there will likely be workarounds inside the requirements, it’s not but been spelled out by any govt, so far as Inexperienced Automotive Experiences is conscious, as as to if or not this could require a brand new technology of {hardware}.
As of but, the checklist of different EVs that may energy the house is a brief one. The Kia EV9 can present residence backup, with {hardware} from Wallbox, and the Volvo EX90’s bidirectional charging options would be the begin of an vitality enterprise tapping into its EVs’ bidirectional charging options. Each of those choices may shift in {hardware}, if not performance, when NACS arrives.

The opposite situation, in fact, is that the automobile must be plugged in to offer residence backup energy. So in the event you’re going by a brownout and have to exit on an errand, or if a downed tree retains you from reaching your storage, it means no energy. For this state of affairs, it is doubtless some owners will, sooner or later, be combining V2H autos with even smaller battery backup.
If that’s sufficient unease to stay with no matter EV you’re driving at this level, the Tesla Powerwall is at the moment at $9,300, minus a 30% tax credit score plus set up. So whereas the {hardware} goes by yet one more iteration, doubtlessly, merely backing your private home up with a Tesla Powerwall is perhaps cheaper and a safer wager in the meanwhile—in the event you don’t want to maneuver your battery backup round on wheels.
