Explore whether V2G will cause the battery in the car to empty

According to foreign media reports, industry insiders have proposed that if using electric vehicles to power the grid, it will lead to the loss of battery power in the user's car. Nissan has refuted this.

LordReddale, chief executive of the Energy Management Association, believes that using vehicle-mounted batteries as energy storage devices is "nonsense" because owners do not want to fill their vehicles with electricity. After all, it takes hours to charge.

Garth Dunsmore, Nissan's European electric car director, refuted the Danish vehicle to the grid(V2G) experience and explained the difference between the service.

He said: "The technology will not empty the battery's power, but use the battery's power to balance the supply and demand of electricity in the grid. "

He added: "The technology does use batteries, and when it still injects electricity into the battery, it keeps the power floating up and down instead of letting it empty. Shorting battery power is of no value to energy companies or users. "

Dunsmore said Nissan's V2G service in Denmark was initially driven by fleet vehicles. Nissan also participated in the British V2G test project, which received funding from the innovative UK and launched both fleet and private electric vehicles.

He said: "This kind of test wants to determine the value proposition of V2G technology for car companies and energy companies." For private owners, the test results will also determine whether the technology meets their value claims. The company believes that private owners will also agree with the technology. "

Ian Robertson, a member of the Boardof Management Council, believes that the promotion of V2G services lies in user awareness.

He said: "The technology not only determines when the car battery is integrated into the grid network, but also determines when the user uses the vehicle. Usually, the appropriate time period is at night, because during that time period, In-vehicle batteries can be used as energy storage equipment and can be used more widely. In any field, only money can attract people's attention. "

Speaking of the market segment for heavy commercial vehicles, British technology manager Mike Kerslake of BYD said that to promote V2G services to this group of users, changes to the service model need to be made in terms of battery ownership and management.

"Owners may not own batteries, but the former can lease them from energy companies," says Kerslake. In this way, energy companies can also obtain value gains from vehicles to the grid. The operating mechanism of V2G technology may change. "

Car companies can also use used batteries, that is, car batteries that are removed from used cars, and use them to reuse batteries or use them as separate energy storage devices. As the number of electric vehicles rises, there will be considerable business opportunities in the future.
