"On January 4, the "Implementation Opinions on Strengthening the Integration and Interaction between New Energy Vehicles and the Power Grid" was officially released to promote the reverse transmission of new energy vehicles to the power grid. Among them, according to the latest policy, Anhui Province's new and updated official vehicles will use new energy vehicles, which are expected to be the first to participate in the interaction of the vehicle network, and the price difference per kilowatt-hour of charging and discharging has reached 0$9.

Vision slowly.
The so-called vehicle-network interaction, simply put, refers to the energy and information interaction between new energy vehicles and the power grid through charging and discharging devices.
It can be divided into intelligent and orderly charging and bidirectional charging and discharging. As we all know, the attribute of the power grid is to use as much electricity as it sends, and there is no waste of more power, and there will be a shortage of electricity if it is not enough, so that the power grid can store electric energy is a worldwide technical problem. For the state, the biggest cost falls on the storage and transportation of electricity.
Promote new energy vehicles to supply power to the grid in reverseIs it really true that the new energy vehicle acts as a movable energy storage "power bank" and obtains the corresponding price difference?
Earn without losing moneyThen give it a tryFrom the perspective of the State Grid, it seems that it is not a small profit.
According toSales data for the first three quarters of 2023 shows that sales of new energy vehicles increased by 30% year-on-year to about 3 million units. Not only that, at the 2024 China Automobile Market Development Summit held by the China Association, the "2024 China Automobile Market Overall Report" was released, and the sales of new energy vehicles in China will reach about 11.5 million units in 2024.
On the one hand, after the implementation of reverse power supply for new energy vehicles, such a large number of new energy vehicle owners have joined the power supply team. Invisibly, the State Grid has a lot of "best businessmen" that can move and store electric energy, which not only solves the transportation of electricity but also solves the storage problem of electricity, and also greatly reduces the cost.
On the other hand, the remaining car owners will supply electricity to the grid in reverse during the peak period of electricity consumption, which greatly improves the utilization rate of electricity. At the same time, it also solves the problem of electricity consumption during peak periods. And this part of the cost of electricity is naturally paid by people who use electricity during peak periods, so why not do it when the wool is out of the sheep?
Be budget-consciousIt's a good dealIn the release of the policy, some netizens calculated such an account. Suppose that in the trough period at night, the owner charges at a lower **3 dimes, and during the peak period, it can be discharged according to the ** of 1 yuan. Each time according to the calculation of 50 kilowatt-hours, you can achieve a profit of 35 yuan. After 2,000 times of charging and discharging operations, car owners can easily earn 70,000 yuan, and such profits are also considerable for many car owners.
Earlier, some domestic and foreign enterprises have begun to try to lay out in this field. Tesla is an early car company in the energy storage business, and the "virtual power plant" model has also been explored more comprehensively, and some Tesla users have also used the "virtual power plant" to make money. According to reports,On August 31 last year, Tesla held the second "virtual power plant" reverse power supply, and some users shared that they earned $75 in one night at this event(about 510 yuan).
Just this week, on January 9, the first batch of 10 V2G charging stations in Shanghai were officially put into operation. Take the NIO 75kWh ET5 model as an example, if the owner uses the trough electricity price at night (let's say 0.3 yuan) to fully charge the battery, cost 22$5. When going to work or going out the next day, the vehicle will be parked at the V2G charging station to supply power to the grid in the opposite direction, assuming that the electricity price is 1 yuan at this time, and the power supply is 40 kWh, you can get 40 yuan income.
It seems to have been earnedIs it really earnedAs soon as the policy came out, some netizens even ridiculed this innovative way, calling it "a new battery of more than 100,000 yuan, which is simply power generation for love". But at the same time,We have to think about a very real issue – battery life. Who will bear the cost of battery life? As we all know, in order to realize daily vehicle-network interaction, it greatly increases our requirements for high-frequency charging and discharging of vehicle batteries, and at the same time, it also brings a great test to the life of the battery. Generally speaking, the battery life of new energy vehicles is 6 years, and the frequency of failures will increase after 6 years, and there will be problems such as reduced mileage, low power storage, and slow charging.
If you charge and discharge 2,000 times as calculated by the previous netizens, you can get a profit of 70,000 yuan, assuming that the grid is recharged 1 time a day on average. Then it needs to be charged and discharged continuously54 years. Under normal circumstances, the life of the battery is 6 years, so in the case of frequent charging and discharging, can the battery allow you to successfully earn 70,000 yuan? Is the battery's reduced battery life due to the reverse supply of power to the grid still counts as part of the warranty?
Of course, successfully back-supplying the grid with a healthy battery is indeed a good idea for energy utilization. If the aging battery is reversed for power supply, will it bring more unsafe hidden dangers? For a long time, many people have questioned the battery safety of trams, and the frequent pictures of trams catching fire on the Internet are really shocking, and if an accident occurs, it is really worth the loss.
Finally
In the report, the implementation opinions clarified the important progress of the initial construction of the vehicle-network interactive technical standard system in 2025, the full implementation and optimization of the construction of the key peak-to-valley time-of-use electricity price market mechanism and the pilot demonstration area. In 2030, China's vehicle-network interaction will achieve large-scale application and comprehensive promotion of intelligent and orderly charging.
Of course, while steadily promoting the policy, it will greatly promote the technological progress of all aspects of vehicles, piles and power grids. It has also played a role in promoting and supervising the development of core technologies for vehicle-to-network interaction, as well as promoting technologies such as long-life batteries, high-frequency charge-discharge batteries, and safety protection.
Protecting the environment is not a one-man move, but a joint effort to maintain it. Of course, I hope that one day in the future it will not be like what netizens complained: "The biggest victim of new energy vehicles, Anhui." ”
