EVs may be able to send electricity back to the grid with the help of vehicle-to-grid technology. This method might make it easier to control energy from renewable sources, and the power supply might work better all the time. EV owners who use V2G might be able to lower their energy costs. However, some people are worried about how long batteries last and how well they work when they are charged in both directions.
Batteries might lose power over time if you use V2G. Scientists have looked into how this might affect the performance of EVs and how to stop it. As more people buy electric cars, it’s important to know how V2G affects batteries. This article talks about V2G technology and how it might affect battery life.
What Are V2G Technology?
With V2G technology, an electric vehicle can both use and make energy. It hooks up the EV to a home, a generator, or the power grid. The battery in the car can store power that can be used right away. Supply and demand on the grid are kept in balance by this method.
In times when green sources aren’t available or during peak hours, V2G helps keep the grid stable by providing electricity. This method makes the best use of the energy that EVs store. It also backs adding clean energy sources like solar and wind power to the system.
This method could cut down on the need for new equipment and the cost of energy. EVs are an important part of today’s energy grid because they can store energy while they’re on the road. The goal is to make the grid smarter, more flexible, and better at using the resources it has now.
Studies That Support The Use Of V2G technology
Warwick University Study (2017)ย ย
A study from Warwick University looked into whether V2G could slow down the degradation of batteries. Based on their model, the best way to charge for driving and V2G might make the battery last longer. Keeping the grid and the vehicle’s energy needs in balance could help keep the batteries healthy and stop them from breaking down too soon. This research shows that V2G could be a useful way to improve performance and make batteries last longer if it is used correctly in real life.
Hawaii University Studyย ย
Hawaii University research showed how reversible charging changes the performance of EV batteries. The study says that constantly charging and discharging batteries might be bad for their health. But if V2G projects are well run, the bad effects might be lessened. The study stressed the need for smart systems that find a balance between grid support and battery use in order to ensure long-term battery performance. This means that a methodical approach is needed for a V2G application to work.
The Roadblocks To Successful V2G technology Deployment
Lack Of Real World Dataย ย
A lot of the time, the results of V2G studies are based on theories and assumptions, with not much evidence to back them up. For example, the Warwick study thought that smart grids and battery management systems (BMS) would work together to figure out how much energy would be needed and available. Since these ideas haven’t been tested in a controlled setting, it’s hard to say what the real effects of V2G are on battery life and grid safety.
Diverse Battery Aging Mechanismsย ย
Different types of EV batteries, like lithium-ion and others, age in different ways because of how they are built and what chemicals they contain. Right now, there is more research being done on alternatives to lithium ion batteries than on these batteries. If V2G is to work all over the world, manufacturers must make age models that are specific to each type of battery. So that EV customers with different battery technologies can be served, this would make sure that V2G apps don’t shorten battery life.
Smart Grid And BMS Integration Challengesย ย
For V2G to work, the Battery Management System (BMS) must make it possible for the EV and the grid to talk to each other. Still, connecting these devices to the grid infrastructure that is already in place is a big problem. To help the BMS keep the grid up to date on energy supply and demand, smart grid solutions need to be made. V2G may become less reliable, and the lack of standard methods and consistent communication could make it take longer to spread.
Infrastructure And Standardization Gapsย ย
The fact that different grid systems and EV makers use different gearbox standards is a big problem with V2G. It’s hard for V2G systems to work with all of them because different manufacturers use different standards. If rules for two-way communication aren’t agreed upon, V2G implementation could be slow and disorganized. Standardizing communication methods across all systems is important to make sure they can work with each other and speed up the adoption of V2G around the world.

Key Issues Hindering V2G Adoption
Lack Of Standardized Communication Protocolsย ย
One big problem with V2G adoption is that there aren’t any standard ways to send data. There are different ways for EV makers to connect their cars to the grid. Systems from different brands and regions can’t talk to each other easily because they don’t work together. Without clear standards, V2G systems might not be able to talk to each other. This would make implementation harder and make it harder for the technology to fit into a global grid network.
Battery Degradation And SOC Managementย ย
A big problem still exists with the connection between wear and tear and battery state of charge (SoC). For V2G to work, batteries have to be repeatedly used down and charged back up. This could hurt the batteries in the long run. This year, the SoC has made a difference; lower SoC levels often mean worse wear. The SoC needs to be managed to stop over-discharge. However, finding the right balance between V2G needs and battery health is still hard, especially in places where high temperatures make damage worse.
How Temperature Affects How Well A Battery Works
The temperature of the area has a big impact on how well batteries work and how long they last. EV batteries are more likely to break down in hotter places, especially if they are charged and drained a lot. This problem could get worse for V2G devices that depend on these regular cycles. Problems with temperature make it harder to use V2G in hot places, like many parts of Asia and Africa, where battery life is already an issue.
Conclusion
V2G technology has a lot of potential to make the grid more stable and use less energy. But there are important problems that need to be fixed. There are problems with battery life transmission standards and real-time battery management that need to be fixed before V2G can be widely used. The risks can be lowered by looking into smarter and more effective battery management systems and filling methods.
In order for V2G technology to work, all manufacturers must talk to each other in a standard way. There are problems, but people are working to make sure that V2G is safe and useful. As more people buy electric vehicles, more research and new ideas will be made in this area. V2G could become an important part of the energy system over time, which would be good for grid providers, EV owners, and the environment.
