Leasing car batteries to the power company - battery energy storage system

SAN DIEGO —
Most people drive only two hours a day on average.
Those expensive vehicles are parked on the street or in the garage for the rest of the time.
But if these cars have a lot of batteries-typically gasoline hybrids today, or in the near future --to-hit-the-
The road-they can earn their master's money when they sit down.
Maybe $5 to $10 a day, just behind it. up energy-
Electric storage system-utility .
Or at least that's the idea behind the v2 g movement.
The panel described this commitment (

Sharing arrangements, one agreed to effectively lease car batteries to power companies when not using car batteries.
This is part of a reporter preview of the annual workshop held here earlier tomorrow.
Ofin San Dimas, president of San Dimas, California, said that to strengthen V2G is not just a theoretical structure

PJM is responsible for coordinating the flow of wholesale power across the entire grid across 13 states and all or part of the Colombian district, which has been involved in three v2 g projects.
They include the more famous MAGICC.
As demand for power grows, PJM will from time to time ask Gage's car to share some of the power stored in the battery.
Later, when the grid has too much power supply, the company will instruct the grid to dump the excess part back into the car's battery. Real-

At least initially, dozens of reporters listened to today's five speakers, and it was hard for them to understand why car owners wanted to put the batteries of their cars on the line to help power companies.
The problem is that Ken Huber of PJM and his panelists have been highlighting the public interest in sharing batteries with the grid without explaining the benefits and presumed protection for owners and vehicles.
In fact, the speaker initially conveyed the impression that the grid could and would charge, run out of the car's battery, and then have the owner refill the charge with his or her dime.
Once Huber understood the confusion, he sharply stressed, "we will not discharge or charge the vehicle.
Instead, he said, "The regulatory signals we send change around zero"-accept and replace a small amount of electricity over and over again.
"So in the day, the battery" will charge and discharge the same amount, "Huber said.
"This means there should be no net loss on the vehicle.
The vehicle may be charged when parking.
He admitted that due to the power-sharing arrangement, "We changed the charging standard a little bit.
But just a little bit-a small percentage.
"In order to increase and withdraw small fee increments throughout the day, the owner will be charged.
This is not a big problem, Huber said.
"But we have paid about $40 over the past year. ” (
He said that this year, with the reduction in fuel costs, utilities may pay more to $28 a megawatt. hour. )
"So if you have a megawatt [hybrid-car]
"The battery is charged, we are charging in the grid, and the daily income is between $800 and $1,000," Huber said . ".
PJM and other utility power brokers are not interested in signing contracts with owners who are occasionally here or there.
They need at least half-
Megawatts or more in the backup batteries.
Therefore, it is very likely that the company will develop into a voluntary party signing the contract, in which members sign the collective lease battery.
It has been struggling for V2G since 1997.
Five years ago, he was in Pasadena, California. -
The non-profit organization dedicated to clean transportation choices published two papers.
They explained the math behind V2G and predicted the economics of this power
Share the arrangement and provide 16 key equations that Kempton says will "let you know what the car can do for the grid and what [its monetary]value is.
"He also calculated how much power grid activity might reduce the battery life of a car.
Kempton said, "What we found out is,V2G’s value]
A little higher than the cost of the car ".
After publishing these calculations, he expects that "the world will be on a path to our doorstep.
"This has not happened.
As a result, he and others have driven the pilot scale test.
For example, in last November, MAGICC integrated the first of the three cars into the East Coast grid.
They are making money every time now, he said.
But today's speaker explained that the real motivation for v2g is what it can do for utilities.
The battery can respond to changes in power demand faster than any other modulator.
When more than thousands or more vehicles are gathered together, they can save utility power users-make money by eliminating the need for utility companies to occasionally use expensive permanent batteries or power plant banks at peak demand.
With V2G, Kempton explains, cars are "part of the grid.
It is controlled by power grid operators but does not affect driving capacity.
"Okay, but how much does it cost to get a car ready to sync with the grid? Maybe a $500 computer controller was added to the battery.
Hybrid.
Oh, one more thing: the grid needs to know when cars can share power.
Therefore, owners may need to report their normal schedule.
Just like when they go to work, shops and cars gather the children in football training. ccer practice.
