The upcoming Volvo EX90 electrical SUV will supply bidirectional charging functionality and be capable of function an influence financial institution for powering home equipment on a tenting journey, charging different EVs, or even perhaps powering the house as a backup, Volvo not too long ago confirmed.
Whereas full particulars on the EX90 aren’t due till November 9, when the EX90 makes an official bow, it’s possible Volvo will use a pack akin to the 111 kwh of CATL cells confirmed for the Polestar 3 that will probably be constructed alongside it in South Carolina—good for a spread of as much as 300 EPA miles. Volvo additionally not too long ago teased a number of 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 a number of extra pointed questions.

Certainly one of 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 further useful resource burden and vitality to fabricate, however in further use-phase emissions to haul that extra weight round for all the automobile life. So a kind of questions was whether or not Volvo, as a really carbon-conscious automaker, is trying to offset the fairly massive pack with the bidirectional functionality.
Primarily based on Loedel’s reply, the reply to that’s sure. “The extra renewable vitality you utilize, and whenever you cost the automotive, in fact, the higher the carbon footprint of the automotive,” he mentioned. “And that is the place with bidirectional charging coupled with totally different use instances and good charging, we additionally help our prospects being extra sustainable within the use part.”

“On the battery aspect, on the subject of the EX90, we wish to cowl all of your wants…however we are also fairly conscious that every day you would possibly solely use a fraction of that, and for this reason bidirectional charging couldn’t solely convey substantial financial advantages to you that scale back vitality but in addition help, extra actively, the grid,” Loedel defined.
Volvo is at present assessing what this implies in carbon numbers, however the end result for that and even financial savings to the tip consumer could be fairly totally different relying on all kinds of variables associated to vitality sources and the ability grid. In Volvo’s dwelling market, Sweden, prospects utilizing time-of-use charging might doubtlessly save 500 euros per automobile per yr. And for those who 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 automotive’s battery to assist buffer the grid sounded lacking intimately.
The reason being, partly, that a lot of these particulars will fluctuate by market. The corporate emphasised that bidirectional charging will initially be launched solely in “chosen markets,” because it at present investigates the potential. Time-of-use charging performance will probably be supplied in every single place although, assured Loedel.

As such, the EX90 will launch with all of the {hardware} vital for vehicle-to-home performance, however Loedel acknowledges that can take extra gear: a bidirectional charging wallbox and residential vitality administration system. The latter will probably be linked 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 Dwelling Integration System that, for $3,895, provides an inverter, disconnect swap, and battery pack to successfully use the truck for dwelling backup energy. Nissan has additionally not too long ago introduced a factory-approved bidirectional charger for the Leaf, within the U.S., that permits the EV to assist buffer the grid. And Hyundai and Lucid have introduced dwelling vitality techniques that to this point lack U.S. particulars.
Volvo mentioned that it’s trying to make all the charging (and discharging) course of “automated and managed completely by the good charging performance within the Volvo Automobiles app.” That may 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 absolutely electrical by 2030, globally, it’s shifting forward with a spread of merchandise on this space.

And to ensure this works in as many markets as doable, 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 watch this ahead—and it could be totally different from one market to the opposite,” mentioned Loedel. “However these two will probably be supported, based mostly on the ISO customary.”
Which 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 techniques.
