I have read lots of comments on why V2V would be a bad idea, but I think it would be a great idea. I worry about my wife and friends not paying close enough attention and running out of battery. If I or someone else could give enough charge to get them to a charger it would make me feel better. Would we be able to do V2V charging with the CT power outlet? We would need software to control how much juice we are willing to give up, charging rate, etc. We would also need cables.
True. I didn't think about the outlets even. There could also be some way to "charge" for The charge of at least a simple way to credit some SC miles to the helper if you wanted.
I’m dying to see what an eel-capable aquatic bike looks like...While V2G whole community’s have been formed to work this concept in some Scandinavian country’s I’ve seen.
I'm with AJDelange on this, its a fantasy.
V2G at the moment has a very marginal cash benefit to the consumer for a tradeoff in battery cycle accelerated degradation (devaluation $$), and vehicle convenience / use.
Due to certain substantial disadvantages inherent in the concept of vehicle battery serving regular consistent power to the grid.
In technical terms we’d call this whole idea “a bit of a wank”.
A/ You have to sign over control of the battery (vehicle) to the Electricity Utility,
or if Tesla wants to act as the intermediary, let them negotiate control with the utility )
B/ Assuming you are able to set a minimum available charge they can not allow power to drop below !
C/ Car needs to be at a fixed address, presume home. Generally meaning not able to be accessed by the Utility during 8am to 6pm at least. Vehicle is away.
D/ Considering for primary use as a car battery, you should be regularly charging your battery to no more than 80%, and you should be aiming to charge it up before it goes below 20%.
And you wish to maintain a minimum charge to use the battery for its primary intended use, driving a vehicle !
So that a vehicle capable of 300 miles (Nominal ) perhaps 50% is the minimum charge you wish to allow the utility to access power down to.
That means 30% of the battery is all you will give over to the grid.
How many shekels can you receive for satisfying all the following conditions before receiving any money :
A/ The times you will be willing to sell power,
B/ Plugged in to sell power,
C/ Not need the additional range in the immediate future
D/ And the utility will want to access power ?
Considering a 300 mile nominal range, means about 265 miles highway range.
Then considering the battery is regularly supposed to be charged to 80% means an approx. range of 212 miles.
Then real world driving efficiency due to conditions / externalities means energy efficiency of 83% which equals 176 miles of range.
As regular battery bottom limit is set at 20%, that is to say, 60 miles. Your total miles available to drive is usually around 116 miles ( 176 - 60 ).
So if you were willing to sacrifice driving range to earn income from the grid regularly.
And sacrifice battery life and car value long term.
So in the case of the Cybertruck Dual Motor, 300 mile range from 100kwh (estimated) battery, if you wish to reserve 58 miles for daily driving use, then you roughly can give over 58 miles of range / to the utility to pay you perhaps !
Say approx. 10 c per kwh for 19.3 kwhrs = $ 1.93 for however many days a year you care to do this for !!
Note Power company won't need to buy it from you every day either.
In my humble view, electric vehicles need as much battery / energy for the primary purpose of driving. Cybertruck’s battery size and power points are a great advantage for, Home Back up battery use and even a little supplemental home energy use, but commercial, or incidental selling power back to the grid, is very minor and hardly worth it when all things considered, especially reduction in battery life/ vehicle valuation.
Yes the case improves for Trimotor Cybertruck with an estimated 200 kwh battery but then you did pay an extra $20,000 u.s !
( $30,500 Aus > $40, 600 after Luxury car tax )
P.S. I know I could have left it at one short sentence, V2G is a bit of a wank.
But then some Tesla disciples may have become apoplectic. Plus I thought I should quantify a little for myself. Please correct me if I have missed something substantial .
Oh' and one very big assumption is made in the calculation above.
All The Power You Sold To The Grid, You Got For Free In The First Place !
I think you'll make the same money riding an exercise bike, or better still, attaching electrodes to the balls of electric eels riding exercise bikes in a pond. Double the output
sucking on a plastic tube to siphon gas and then getting some gas in the mouth... yeah, helping a fellow motorist out by simply owning a V2V cable is a great thing (with no aftertaste!).
