The upcoming Volvo EX90 electrical SUV will supply bidirectional charging functionality and be capable to function an influence financial institution for powering home equipment on a tenting journey, charging different EVs, or maybe even powering the house as a backup, Volvo lately confirmed.
Whereas full particulars on the EX90 aren’t due till November 9, when the EX90 makes an official bow, it’s doubtless Volvo will use a pack corresponding to the 111 kwh of CATL cells confirmed for the Polestar 3 that shall be constructed alongside it in South Carolina—good for a spread of as much as 300 EPA miles. Volvo additionally lately teased just a few particulars on how this vitality performance will work; and Inexperienced Automobile Reviews adopted up with Olivier Loedel, Volvo’s head of electrification ecosystem, to ask just a few extra pointed questions.

One among them pertains to carbon footprint. Volvo has confirmed that the EX90 will supply a battery pack bigger than 100 kwh. For Volvo and anybody involved about sustainability, that’s fraught, as bigger battery packs add to the automobile’s carbon footprint—not simply in additional useful resource burden and vitality to fabricate, however in additional use-phase emissions to haul that further weight round for the complete automobile life. So a kind of questions was whether or not Volvo, as a really carbon-conscious automaker, is trying to offset the somewhat massive pack with the bidirectional functionality.
Based mostly on Loedel’s reply, the reply to that’s sure. “The extra renewable vitality you utilize, and once you cost the automobile, after all, the higher the carbon footprint of the automobile,” he mentioned. “And that is the place with bidirectional charging coupled with totally different use instances and good charging, we additionally assist our prospects being extra sustainable within the use part.”

“On the battery aspect, in the case of the EX90, we wish to cowl all of your wants…however we are also fairly conscious that each day you would possibly solely use a fraction of that, and for this reason bidirectional charging couldn’t solely carry substantial financial advantages to you that cut back vitality but in addition assist, extra actively, the grid,” Loedel defined.
Volvo is at the moment assessing what this implies in carbon numbers, however the end result for that and even financial savings to the top consumer will be fairly totally different relying on all kinds of variables associated to vitality sources and the ability grid. In Volvo’s house market, Sweden, prospects utilizing time-of-use charging might doubtlessly save 500 euros per automobile per yr. And in the event you add vehicle-to-grid, that may go as much as 800 euros per automobile per yr.
That’s why, when in a launch, the mix of time-of-use charging and superior bidirectional functionality that may finally use your automobile’s battery to assist buffer the grid sounded lacking intimately.
The reason being, partly, that lots of these particulars will range by market. The corporate emphasised that bidirectional charging will initially be launched solely in “chosen markets,” because it at the moment investigates the potential. Time-of-use charging performance shall be provided in every single place although, assured Loedel.

As such, the EX90 will launch with all of the {hardware} needed for vehicle-to-home performance, however Loedel acknowledges that may take further gear: a bidirectional charging wallbox and residential vitality administration system. The latter shall be related to the house’s panel, to the cloud, and to the Volvo.
Thus far, the one automaker to supply such {hardware} is Ford, with the F-150 Lightning and its Ford Cost Station Professional and Residence Integration System that, for $3,895, provides an inverter, disconnect change, and battery pack to successfully use the truck for house backup energy. Nissan has additionally lately introduced a factory-approved bidirectional charger for the Leaf, within the U.S., that enables the EV to assist buffer the grid. And Hyundai and Lucid have introduced house vitality programs that to this point lack U.S. particulars.
Volvo mentioned that it’s trying to make the complete charging (and discharging) course of “computerized and managed completely by the good charging performance within the Volvo Automobiles app.” That will permit and encourage charging throughout off-peak hours when the grid is much less burdened and costs are low.
Loedel hinted that, given the automaker’s plan to go totally electrical by 2030, globally, it’s transferring forward with a spread of merchandise on this space.

And to ensure this works in as many markets as potential, Volvo has made its {hardware} prepared for various variations of bidirectional charging. Meaning Volvo is together with {hardware} to go AC or DC with the tech in each EV90.
“We’re going to allow each AC and DC bidirectional charging, and we’ll proceed to observe this ahead—and it might be totally different from one market to the opposite,” mentioned Loedel. “However these two shall be supported, primarily based on the ISO commonplace.”
That will take some firmware updates or software program to fine-tune, however Volvo is prepared for that, too. It’s anticipated to supply over-the-air updates with the EX90 that permit entry to the total vary of auto firmware and programs.
