Difference between V2G and V2H

Electric mobility will soon become the new rule as more drivers switch to electric vehicles every day. Our research shows that the vast majority of EVs want to make charging their car at home easier, with energy efficiency topping the wish list for nearly the same proportion of EVs when purchasing an EV charging station.

Summary:

It's no surprise that more and more people are interested in the smart charging capabilities of electric vehicles. This is a series of intelligent functions that optimize the car charging process.

Despite the undeniable popularity of electric vehicles, their batteries are still considered more of a disadvantage than an advantage. But what if your car's battery not only consumes energy, but can also be a source of energy storage?

This is made possible by the growing - and evolving - capabilities of the car-to-network (V2G) and the home car (V2H). These new technologies hold great promise as they have the potential to completely change the way electricity grids work and the way vehicles are used.

However, there are many unknowns. This article details which vehicles are online and which are in your home, and how property owners can benefit from it.

What is vehicle-to-network (V2G)?

An often overlooked statistic is that, on average, a car only spends 4% of its time behind the wheel. In other words, the remaining 96% of the time spent in the parking lot, the car spends behind the wheel.

This means that the vehicle is idle for most of the day.

Network vehicles are useful at this stage. Unlike internal combustion vehicles (ice), electric vehicles (EVs) have large batteries that can store a significant amount of energy.

What if that battery capacity could be used to store power from the grid and provide extra power to balance fluctuations in power consumption?

Vehicle to Grid Technology (V2G) unlocks the battery in electric vehicles and enables bi-directional charging between the vehicle and the grid. Simply put, V2G allows electric vehicles to temporarily return to the grid depending on the demand for electricity at a certain time.

This is a big advantage for energy providers, who can use EV batteries to meet peak electricity demand without having to increase generation. It is also an important tool for smoothing fluctuations in renewable energy production by compensating for times when sunlight and wind are not blowing.

Why V2G Matters

With the growth and development of electromobility, the electric grid must adapt to the exponential growth in the number of electric vehicles that need to be charged by both individual consumers and commercial vehicles. Standards for communication and coordination of energy flows between cars and charging stations were released in 2022. This may speed up the introduction of two-time charging. However, legislation and tax regulations are still under development, and mass adoption of V2G is still a long way off.

What is car-to-home (V2H)?

The meaning of car-home (or v2h) is very similar to car-web. The difference is that with V2H, the energy is used to power the home rather than being returned to the grid.

A household car allows the homeowner to control energy consumption and can transfer some of the energy consumed from the grid during off-peak times when energy prices are low.

To understand this, imagine a situation where you are at home, your electric car is charging on the road, and you are doing your homework. Many devices are running and drawing a lot of power from the grid, and with V2H you can use some of the energy stored in your electric vehicle to power your devices, reducing grid power consumption.

Once the appliances are finished and switched off, the mains-powered car battery can be recharged overnight to take advantage of the lowest prices during peak periods. So you can quickly reduce your electricity bill by transferring some of the energy you use when prices are cheaper.

This is very advantageous, since the maximum consumption of an average house is about 3-4 kW. As a rule, automotive devices can operate from a car battery for 12-20 hours.

In addition to saving money, V2H is also a way to prevent congestion and provides an additional source of energy if electricity demand exceeds the capacity provided by the grid. It can also act as a backup power source in the event of a power outage, allowing you to power your home without a generator or batteries.

Will my electric car always be fully charged with V2H?

One of the main problems when using V2H is the level of charge of the electric battery, since using it as a power source consumes some of the battery power.

As mentioned above, in most cases, electric vehicles are not used. So even if you don't know it, there are many days when your car can give you energy. For example, let's say you come home from work in the evening and don't leave the house until the next day. You can easily use an electric car to power your home in the evening and not start charging it until midnight. At the current charging rate, you wake up with a full battery.

And that's not to mention that the vast majority of daily commutes are far less than today's electric vehicles.

Storage of renewable energy from V2H and solar panels

Switching from a car to a home can further increase the energy consumption of a home if, for example, solar panels are used to generate electricity. Solar panels themselves only produce energy when the sun is shining. This may not happen even when using the most energy. For example, if you cook dinner after sunset, you can use more electricity at night.

Using a household car, you can store the renewable energy you produce, charge your electric car during the day, and use some of that energy at night to meet your electrical needs. So your car powers your house at night and you don't have to buy electricity - or you can buy less - from a supplier.

Of course, you can always make sure that your electric car stays fully charged the next day and does not use more energy than you would like for your home.

Is V2H currently available?

No. However, the dual charge function in the example above only works with this model, charging station, and software. Regulatory issues and the lack of a standard EV two-way charging protocol and connector types will impact growth. Assuming all of this is already happening, we expect V2H to become widely available in the next three to five years.

Are V2G and V2H battery safe?

A particularly important issue for electric vehicle batteries is battery life. Drivers want their cars to last for years. And an important aspect is battery performance.

Like many other components, electric vehicle batteries wear out over time. With each charge cycle, the battery wears out a little, thereby reducing the amount of power over time. Battery capacity loss in electric vehicles is estimated to be around 2.3% per year - and that's at a very low rate. This means that an electric car with an initial autonomy of 240 kilometers will lose only 27 kilometers from the available autonomy after five years of operation.

In practice, maintaining an incompletely charged battery for an extended period of time is worse for battery life than normal daily use. Therefore, most manufacturers recommend maintaining battery levels between 20% and 80% to maintain optimal performance.

Smaller charges and discharges, for example,  also causes less damage to the battery than driving. This is because the energy intensity generated by driving an electric vehicle heats up the battery more than a lower and more stable load from charging and discharging, and heat is a major factor in battery degradation.

Two studies supported this by analyzing the degradation of electric vehicle batteries when using V2G to return energy to the grid. They found that when using smart algorithms to manage charging, there was no significant additional loss in battery capacity compared to normal operation.

What is the difference between V2X, V2G, V2H and V2B?

In addition to V2G and V2H, you may have heard abbreviations such as V2X, V2I, V2P, and V2B. Many acronyms have nothing to do with charging until your brain explodes. To eliminate confusion, the meanings of each are explained below.

A car for everything (V2X) is a term used to describe the overall concept of a car connected to the environment. Beyond the energy storage aspect, V2X is commonly associated with connected systems that improve driving safety. In this sense, there are many gradations.

For example, Vehicle-to-Infrastructure (V2I) refers to the connection between a vehicle and surrounding infrastructure (eg traffic lights, road signs). Returning to the aspect of power exchange, Vehicle-to-Building (V2B) technology is similar to V2H, but refers to the exchange of power between a vehicle and a building, rather than a company or workplace.

What's in the future?

While V2G technology is still in its early stages, it could be an important EV charging feature as it offers many benefits for both network operators and EV drivers. As the number of electric vehicles on the road increases, societies around the world will need to find ways to effectively manage their electricity consumption and meet growing demand.

Homeowners can better manage the flow of electricity in their homes through vehicle-to-home (V2H) connectivity, making them independent of control networks; V2H also promotes sustainable energy production through efficient storage and use of renewable energy in the home.
