And feed the electricity back to the grid.

In the next few years, electric vehicles can help power millions of homes, just by using their battery power. The electricity in the vehicle battery can be reconnected to the grid instead of being stored. This technology was pioneered in Japan, and our research will help understand how to best use it in the UK.

Many electric vehicles (EVs) are produced that can use their on-board batteries to send electricity back to the connected power source. Whether it's the owner's house or the grid more generally, these technologies are dominated by the government and electric car manufacturers, mainly to balance the demand for the transmission network or the grid.

The ability to use these huge connected batteries is in line with the future management and provision of a cleaner grid-we should use clean renewable energy such as wind and solar instead of burning fossil fuels to generate electricity, and if sufficient, store electricity in batteries In case of emergency. no. Therefore, by using renewable energy to charge electric vehicles, we can reduce greenhouse gas emissions.

The plan sounds good, but because electricity is difficult to store, it becomes tricky. But we have stored a lot of electricity in the car. At present, about 1% of the 27 million households in the UK have electric vehicles, and each household is equipped with an average of 60 kWh batteries. These 300,000 electric vehicles can store an incredible 18 GWh of electricity, which can be used to power the home. This is more than the Dinorwig pumped storage power station in Snowdonia, the largest storage facility in the UK, which has a storage capacity of approximately 9 GWh.

By 2030, there will be nearly 11 million electric vehicles on the road in the UK. Assuming that 50% of these vehicles can feed unused energy back to the grid, this will provide electricity to 5.5 million households.

In order for the car to provide power to the grid on a technical level, three things need to be done. First, it should be possible to achieve two-way power transmission from the car to the charging point. This system is called vehicle-to-grid and was first introduced to Japan after the Fukushima disaster and subsequent power shortages.

But to launch this technology, more areas of development are needed. These include installing car-to-grid charging hardware in the home, vehicle compatibility, and energy market changes. There are also two competing types of fast charging devices that need to be resolved, possibly devices with two types of connectors.

The third part of the technical problem is to ensure the support of the distribution network. Certain parts of the grid cannot simultaneously transfer large amounts of electricity back through connections, so the local network needs to ensure that they can cope.

Once the technology is in place, how do we ensure that people participate in the program? We are studying consumer acceptance and knowledge of the vehicle-to-grid system in order to show drivers how the technology works and prevent their batteries from draining when needed.

Currently, most trials are conducted by energy companies or distribution companies who want to figure out how the technology can operate commercially and help balance the grid. But we believe that the focus should also be on cost-effectiveness, ecological certification and driver convenience.

Charging electric cars with the cheapest energy and selling the energy back to the grid during peak hours can enable customers to earn up to £725 a year. In addition to fuel cost savings, the average operating cost of an electric car is 500 pounds per year, while gasoline or diesel is 1,435 pounds per year.

Reducing the impact on the environment, saving fuel costs, and using cheap, clean energy to power your house are all great benefits, but the lack of car battery power may cause dissatisfaction with many car owners.

Other issues include: the potential cost of installing a compatible V2G charger in the home; the impact on lifestyle, and the inconvenience of delaying plug-in electric vehicle charging (if the car powers the house); and the fear of battery degradation (some studies indicate this) Makes sense, but is offset by potential benefits).

Ofgem, the British electricity and gas regulator, intends to invest millions of pounds to create a more flexible energy system to support the electrification of vehicles and the generation of renewable energy, and to make the transition to a low-carbon economy more fair, inclusive and affordable.

If enough drivers use the Internet of Vehicles technology, the UK can obtain the power generation capacity of up to 10 large nuclear power plants, and reinvest the saved costs in the development of clean energy and flexible energy systems.

The process will not be smooth sailing. There are many solutions, but they all need the support of power companies, even automakers and financial companies. There are many problems to be solved, but since an ordinary car has not been used 95% of the time, the possibility that its power supply can be used for a more environmentally friendly and cheaper life is huge.
