Or they could use EVs. Require cars to have V2X (Vehicle to Grid, Vehicle to Load) feature. EV batteries are humongous.

Nah, people want to wake up in the morning and know they can drive somewhere.

Requiring it is crazy.

As a consumer, would you want the extra usage on your battery? Those extra cycles have to cause some additional degradation to the system, but I do not know how much.

I feel like this is likely going to be a non-issue in practice. Because these batteries are rated to last at least 10 years either way. And by that time, the cost of replacement will be dramatically cheaper.

They are rated to last at least 10 years (under X usage conditions)

They won't last nearly that long under Y usage conditions if Y is substantially larger than X

How much would I get paid?

Net metering rates are pretty poor, so I would guess not much outside of extreme grid instability. Although, you then might want to selfishly hoard the juice for yourself.

It would not be selfish to run your home off the car battery during peak rates and therefore cutting peak demand on the grid. Everyone wins.

Do any of the EVs sold in the US support Vehicle to Grid?

▲happyopossum 3 hours ago | parent | next [-]

Many do - teslas, ford lightnings, Kia ev9, all the GM Ultium stuff (Silverado etc, hummer ev, Cadillacs), and a bunch of others.

Isn’t Tesla V2G just for Cybertruck?

▲danans 2 hours ago | parent | prev | next [-]

Yes, but last I checked the bidi chargers were proprietary - tied to vehicle manufacturer - which is a huge disincentive. I don't want my home's battery connector locked into a vehicle brand/manufacturer.

▲WarmWash 3 hours ago | parent | prev | next [-]

Lightnings do (well before they were discontinued)

But given they are NMC chemistry, you probably wouldn't want to cycle them a lot for the grid (or just your home).

▲everybodyknows 2 hours ago | parent [-]

You wouldn't have to, to nevertheless provide great benefit to the grid. Look up "TOU billing".

▲oori 2 hours ago | parent | prev [-]

Many do (assuming bidirectional charger), but it’s only 3.6kW max, in most cases

▲bethekidyouwant 3 hours ago | parent | prev [-]

The down votes are because you use the word require. They’re never going to require it it would be opt in.

I think they mean to use EV batteries would require the EV to be designed for V2G capability, which is currently rare
