Yeagerson: V2G capability is three to four times more valuable than V1G
Ty Yeagerson · Can the V2X dream become reality? · Aug 31, 2023 · at 23:19
Ty Yeagerson, V2X Lead at General Motors, explains the economic differences between unidirectional managed charging (V1G) and bi-directional vehicle-to-grid (V2G) technology.

“If you think about V one G value, it's only a negawatt capacity if the vehicle is not charged. And a lot of times what happens, people bring their vehicle someplace, they plug it in, and it's charged, and so you've got basically negawatt capacity for as long as it's sitting there either charging or maybe about to be charging. But if you have V to G, then it's basically, it's got capacity in some form available for the entire time that it's plugged in, because most of the time you'll be able to take a little bit of power out, and you can also defer from a potential charge happening. And so, if you think about, there's maybe, you know, for V-I-G, there's millions of cars out there, a very large percentage of which are not useful to the grid at all, because they're already charged. So, so it's not just double, it's like, and the math can be done several ways, but it's really three or four times as valuable for a given vehicle.”

Yeagerson: EV grid value derives from power capacity, not deep cycling
“The value of these batteries is going to be more in the power than in the energy, and it's going to be more in the capacity than in the KWH, right? So you're gonna have, the value is that these things are gonna be available and, you know, maybe sometimes used …”
Yeagerson: Aggregated EV fleets will become highly dispatchable grid capacity resources
“If you have a million thermostats and you've done it 20 times, then actually it's more dispatchable than a discrete peaking resource. And I think you're gonna find that with vehicles as well. It's gonna be very fungible, it's gonna be very predictable, we're g…”
Yeagerson: Utility rates will soon tie directly to managed charging participation
“My guess is that what we're going to see before too long is utility programs or state subsidy programs where where you're charging capacity or you, your utility rates are going to be charged relative to your participation in these types of programs.”
Yeagerson: Consumers will widely accept managed charging for modest cash compensation
“Eventually that the adoption rates for this stuff are going to be high just because I think it's going to be very widely accepted and everyone's going to know that they're going to get a little bit of trickle cash coming through these functions and people will…”
Yeagerson: Existing utility managed charging programs will transition directly to V2G
“We don't have any programs going with utilities for V to G mode, but I think the expectation in the industry is that what happens is these existing programs with utilities just roll right into V to G programs.”
Yeagerson: In-vehicle telematics offer superior flexibility for managing EV charging
“I think our perspective is, is you get the most flexibility if you can control it on the car, because the car is going to go different places, and you could, you know, one point of connection gives you, V one G capabilities anywhere you go.”
