EV-to-EV charging: F-150 Lightning and Ioniq 5 both do it and here's how
Bengt Halvorson

If you’ve lived around an electric vehicle, you know that flexibility is key. While daily charging at home or at road-trip stops covers most needs, what if friends or family with EVs could lend a few miles to you in a pinch?

That’s where something in the ability set of several upcoming EVs might come in very handy: their potential to rival standalone gasoline-powered generators, and reliably provide enough power, for long enough, to charge up another EV.

That’s something that the upcoming Ford F-150 Lightning electric pickup (or the F-150 Hybrid) can do, with their Pro Power Onboard feature. They can produce up to 7.2 or 9.6 kw—enough to give a Mustang Mach-E 20 additional miles of range per hour, or an F-150 Lightning 13 miles per hour.

As Ford points out, those Hybrid or Lightning drivers can plug an EV’s mobile charging cord into Pro Power Onboard’s 240V outlet. Then most smaller EVs with such a cord might be able to take advantage of full (or nearly full) Level 2 charging speed.

Or, if you only have your 120V charge cord, you’ll be able to plug that into Pro Power Onboard’s 20-amp, 120-volt three-prong outlet, providing Level 1 charge rates that might give you a few miles an hour—which might be all that you need to get to something faster. And with four electrical outlets in the F-150 Lightning’s frunk you get up to 2.4 kw of power, which means you could split the total up among charging an EV and running some tools.

Ford isn’t the only vehicle maker teasing such a feature. The first one to offer it in the U.S. market will be the Hyundai Ioniq 5. Its Vehicle to Load (V2L) feature will supply 3.6 kw of continuous power

Future accessories to connect to a home energy ecosystem will allow access to its full 3.6 kw, but it can supply 1.9 kw peak power (about 16 amps) through its 120V outlet—essentially allowing most charging cords to allow

Both models have bigger aspirations about what to do with the power. As Ford outlined with the reveal of the F-150 Lightning earlier this year, it will be one of the first electric vehicles to take advantage of bi-directional charging in the U.S. market—effectively enabling households to use the electric truck as a gigantic power bank that might be used as emergency power, or as an energy buffer with solar, on the way to greater energy independence.

Ford points out that, as part of the company’s forthcoming Intelligent Backup Power system, the feature is enough to power a home for up to three days in a power outage. Taking full advantage of that will require an 80-amp Ford Charge Station Pro, a home energy management system, and an inverter, which Ford plans to bundle together. But to output that power for EVs, appliances, or camping, you only need Pro Power Onboard.

Hyundai meanwhile has said that solar will be part of its Hyundai Home service, integrating charging, solar, and energy storage and including "one of the best warranties in the industry," just like the cars.

Tesla doesn’t yet offer this functionality from its vehicles, although we’ve seen teases of it in the first vehicles that are now being delivered from Rivian and Lucid.

They’re not the first. The Nissan Leaf, with its CHAdeMO fast-charging interface, was nearly ready for such tasks from its launch, more than ten years ago. Although home energy systems were offered for the Leaf officially in its home market of Japan and on a pilot-program basis in Europe, Nissan never made this functionality accessible to Americans, but some independent companies are now pushing ahead and using it.

A decade ago, AAA started investing in trucks that could provide emergency charging to EVs, expecting that amid reports of range anxiety, it would be a popular service. But they found, surprisingly, that EV owners seldom got stranded. With this casual way to gain just a few miles from another EV, an extra little bit of flexibility might go a long way.

More on Lightning to Lightning charging here:

The Ford F-150 Lightning Will Be Able to Charge Other Lightnings
Vehicle-to-vehicle charging has been a white whale for EVs, but Ford says it's figured it out.
BY JERRY PEREZ NOVEMBER 19, 2021

The upcoming 2022 Ford F-150 Lightning electric pickup will be a game changer, for sure. Promising the capability people have come to expect from the best-selling F-150 while also introducing battery-electric performance (and its pros and cons) to a traditional fanbase will be no small feat. However, Ford has a trick up its sleeve that may finally persuade truck owners to go electric: The F-150 Lighting will be able to charge other F-150 Lightnings.

In conversation with the truck's chief engineer Linda Zhang at the 2021 Los Angeles Auto Show, we learned about the lengthy process Ford went through to squeeze the most performance and practicality out of its upcoming pickup. One of those key traits revolves around the truck's ability to act as a rolling battery and power generator, which allows it to share its electric charge with other devices—which up until recently we knew could be anything from camping gear to an entire house. Now, it turns out the Lightning will have vehicle-to-vehicle charging capabilities via its main charging port.

"We are [working on] a vehicle-to-vehicle system," Zhang told The Drive. "[Charging other EVs] is going to be dependent on the power cord, and the Mach-E system is not set up for that right now, but Lightning will be."

Zhang went on to say that theoretically, an F-150 Lightning could charge any electric vehicle, but the charging cord and electrical architecture compatibilities are the limiting factors. So at first, the truck will only be able to share its charge with other F-150 Lightnings.
Zhang explained that the idea really spawned from the success of the current hybrid F-150 PowerBoost, which can use its onboard generator to power a variety of external devices, including an entire home if the home is equipped with an inverter (as we've explained before).

"We have a battery system that you can pull electricity from, in this case, 9.6 kilowatts of power via 22 different outlets around the truck; 220v, 110v, USB, and 12v. As we thought about this Pro Power Onboard technology and we heard from people who were using it [in the hybrid F-150] to back up their refrigerators and homes during power outages, we developed the theme more [in the Lightning]," Zhang added. "We ended up with something called Intelligent Backup Power. It uses the Lightning's actual charging port on the side of the truck, where you plug it in to charge, to do bidirectional power transfer with the extended range batteries, turning the truck into a mobile backup generator on wheels for an entire home ecosystem paired with a home inverter."

Going one step further and having the ability to share a charge with another compatible EV is really quite the breakthrough, even if for now it's limited to the same make and model. Some smartphones are already able to share a battery charge with other compatible smartphones, and Rivian CEO RJ Scaringe told this very outlet back in 2019 that his company was planning V2V charging for the R1T, though that tech didn't make it into the production model launched this fall.

Being able to help a fellow Ford owner because they don't have enough charge to make it to their destination is important (and will surely help with range anxiety), but I believe the real advantage to this technology will play out in fleet and/or commercial applications. Being able to top off trucks in the field and essentially shuffle power around to vehicles that need it can be extremely attractive to companies that manage hundreds or thousands of vehicles in construction, mining, utility, and other industries that rely heavily on trucks.

Zhang did not elaborate on when this capability would extend to other Ford vehicles, but given that the necessary changes involve hardware and software, it will likely be a bit. For now, however, potential Lightning owners can rest easy knowing that if they're ever in a tough spot, all it takes is another friendly Lightning driver to get them out.

Gimmick. The Juice Box or other small EV charge kit doesn't care whether it's plugged into an outlet in your garage or a receptacle in Ford truck. This is a waste of a press release.

A future DC to DC device that handles handshake WOULD be a step forward.

That's what they discussed in the second post:

There was a better post on that with more details that I will have to find an re-post here.
