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 maybe even powering the house as a backup, Volvo just lately 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 corresponding to the 111 kwh of CATL cells confirmed for the Polestar 3 that might be constructed alongside it in South Carolina—good for a variety of as much as 300 EPA miles. Volvo additionally just lately teased a couple of particulars on how this power performance will work; and Inexperienced Automotive Studies adopted up with Olivier Loedel, Volvo’s head of electrification ecosystem, to ask a couple of 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 car’s carbon footprint—not simply in further useful resource burden and power to fabricate, however in further use-phase emissions to haul that extra weight round for all the car life. So a kind of questions was whether or not Volvo, as a really carbon-conscious automaker, is trying to offset the slightly massive pack with the bidirectional functionality.
Primarily based on Loedel’s reply, the reply to that’s sure. “The extra renewable power you utilize, and once you cost the automotive, after all, the higher the carbon footprint of the automotive,” he mentioned. “And that is the place with bidirectional charging coupled with totally different use circumstances and sensible charging, we additionally help our clients being extra sustainable within the use section.”
Carbon footprint for Volvo C40 Recharge vs. XC40 ICE relying on power sources
“On the battery facet, in relation to the EX90, we need 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 this is the reason bidirectional charging couldn’t solely convey substantial financial advantages to you that cut back power but in addition help, 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 person might be fairly totally different relying on all kinds of variables associated to power sources and the ability grid. In Volvo’s residence market, Sweden, clients utilizing time-of-use charging might doubtlessly save 500 euros per car per yr. And for those who add vehicle-to-grid, that may go as much as 800 euros per car per yr.
That’s why, when in a launch, the mixture of time-of-use charging and superior bidirectional functionality which may ultimately 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 the moment investigates the potential. Time-of-use charging performance might be supplied all over the place although, assured Loedel.

As such, the EX90 will launch with all of the {hardware} mandatory for vehicle-to-home performance, however Loedel acknowledges that can take extra tools: a bidirectional charging wallbox and residential power administration system. The latter might be related to the house’s panel, to the cloud, and to the Volvo.
To date, 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 change, and battery pack to successfully use the truck for residence backup energy. Nissan has additionally just lately 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 residence power programs that thus far lack U.S. particulars.
Volvo mentioned that it’s trying to make all the charging (and discharging) course of “computerized and managed totally by the sensible charging performance within the Volvo Vehicles 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 variety of merchandise on this space.

And to ensure this works in as many markets as attainable, 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 are going to proceed to watch this ahead—and it could be totally different from one market to the opposite,” mentioned Loedel. “However these two might be supported, primarily based 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 complete vary of car firmware and programs.
