Electric cars could help millions of households in the years to come. Instead of storing electricity, the battery can be plugged into a grid. The technique was pioneered in Japan and our research will help us understand how to make the best use of it in the UK.
Many electric vehicles (EVs) that are being manufactured have the capacity to use the on-board battery to send power back to the connected power supply.
That owner’s house or electric grid generally these technologies are developed by government and electric car manufacturers primarily to balance the demand for a power transmission network or grid.
The ability to use these giant connected batteries respects future management and clean grid supply – when should we use more renewable energy sources such as wind and sun and store electricity in batteries instead of burning fossil fuels? no I do not. So we can reduce greenhouse gas emissions by recharging electric vehicles from renewable sources.
The plan sounds great, but it is difficult because it is difficult to store electricity. But we already have a lot of electricity – we store it in our cars. About 1% of the 27 million households in the UK own EVs, each with an average of 60 kilowatt hours of battery life, and these 300,000 EVs store an incredible 18GW of electricity, which is used to power homes.
This is larger than the UK’s largest storage facility at around 9 GWh, the larger Denorwig pump storage plant in Sedonia.
By 2030, the UK will have about 11 million electric vehicles on the road. It is estimated that 50% of these vehicles are able to recycle unused energy into the grid, creating opportunities for 5.5 million households.
How do we make it happen?
In order for cars to be technically grid, three things must happen. First, a two-way power transfer must be made from the car to the charging station. This system, known as the vehicle-to-grid, was first introduced in Japan after the Fukushima disaster and the ensuing power outage.
But there are additional areas of development that need to be addressed. These include changes from vehicle to grid in-house hardware installation, vehicle compatibility and energy market changes. There are also two types of fast charging competitors, which need a solution, perhaps with units with both types of connectors.
The third part of the technical puzzle is to ensure support from power distribution networks. Some parts of the grid cannot transmit large amounts of energy through connections at the same time, so they must ensure that local networks are able to withstand them.
Once the technology is in place, how do we ensure that people are involved in the planning? We are studying consumer acceptance and vehicle-to-grid systems with the aim of showing drivers how the technology works and preventing their batteries from becoming flat when needed.
Currently, most experiments are carried out by energy companies or power distribution companies to find out how the technology works in the market and to help balance the power grid. But we believe that attention should be paid to cost benefits, ecological evidence and driver convenience.
Charging the cheapest electric vehicles and selling them to the grid at peak hours can provide customers up to £ 725 a year. In addition to saving on fuel costs, an EV costs an average of £ 500 per year for ወይም 1,435 per liter of fuel or diesel £ 1,435 per year.
Reducing environmental impact, saving on fuel costs and upgrading your home for cheap and clean energy are all great benefits, but if the car battery is low it can irritate many homeowners.
Other concerns include the potential costs of installing V2G chargers that are compatible with your home; Influences on lifestyle, and the inconvenience of charging a slow plug electric vehicle (if the car is running at home); And fear of battery failure (some studies suggest it is true, but it exceeds the potential benefits).
Ofgem, the UK’s electricity and gas regulator, plans to invest millions of pounds to support vehicle electrification and renewable energy and create a more equitable and inclusive energy system for the transition to a lower carbon economy. And affordable.
If enough drivers use grid-to-grid technology, the UK will be able to generate clean energy and renewable energy systems by having the capacity to generate up to ten large nuclear power plants and repaying savings.
The process will not be smooth. The solutions are many, but they need the support of energy companies, as well as car manufacturers and financial companies. There are many parts of the puzzle to solve, but since the average car is not used 95% of the time, the potential for green and cheap living is very high.
