V2G, V2H, and V2L: A Complete Guide to EV Bidirectional Charging

Recharging an EV is second nature to owners — it’s essential for a fresh start each day. But did you know that certain EVs can also provide power to other devices, vehicles, or even a home or grid? This innovative feature, known as bidirectional EV charging, opens up a world of possibilities.

In this article, we’ll break down the different types of bidirectional charging, explore its benefits and limitations, and share a list of EVs that support this groundbreaking technology.

Although it might not be obvious at first, EV bidirectional charging comes in various forms depending on the type of energy receiver. So, what exactly is bidirectional charging? This innovative technology enables energy transfer fr om electric vehicles to external receivers. The next question is: why would we need to draw energy fr om our EVs for external use? To answer this, let’s explore the different types of EV bidirectional charging.

Let’s begin with the simplest and most accessible form — V2L. This system allows energy transfer fr om an EV’s battery to electric appliances, such as a kettle or hairdryer, through the on-board charger.

Some EVs also support V2V (Vehicle-to-Vehicle), a subset of V2L, which enables one EV to charge another using its on-board charger — a truly remarkable feature.

V2L proves to be highly practical in scenarios where powering appliances is necessary. For instance, imagine visiting a national park, connecting a special adapter to your charging port, and brewing tea with an electric kettle. Isn’t this the future we’d all love to embrace?

The next technology is particularly appealing to EV owners, especially those living in standalone homes, as it allows an EV to power an entire house. V2H operates on the same principle as V2L but requires a bidirectional EV charger capable of transferring energy fr om the car’s AC charger to the home. This technology is even more remarkable than V2L, as it not only helps reduce home energy costs but also serves as a reliable backup power source in case of grid outages.

At first glance, V2G might seem like a complex and even questionable concept — why should EV owners return electricity to the grid fr om their vehicles? However, this technology is far more practical and beneficial than it initially appears.

The primary goal of V2G is to reduce strain on the grid during peak demand periods and contribute to lowering carbon emissions. The process is straightforward: your EV charges during off-peak hours and returns energy to the grid during peak usage, helping stabilize the system and prevent waste.

Additionally, EV owners participating in V2G programs can earn compensation fr om utility companies, making it a win-win for both the grid and the owner.

The concept of V2X is the pinnacle of bidirectional charging technology. While few current EV models offer comprehensive support for V2L, V2H, and V2G simultaneously, advancements in the field suggest that such vehicles will soon emerge. The arrival of fully V2X-capable EVs will mark a transformative moment, ushering in a new era for energy efficiency and mobility.

With a clear understanding of bidirectional charging and its primary types, we can now dive into the top advantages that this cutting-edge technology provides:

  • Saving Energy: Depending on the type of bidirectional charging used, this technology can contribute significantly to energy savings. With V2G, you can support the environment by reducing energy waste during peak demand, while V2H allows you to power your home directly fr om your EV. For homeowners with solar panels, an EV equipped with V2H capabilities can substantially lower or even eliminate electricity costs. During the day, solar panels generate free energy, and at night, the EV provides additional power — an ideal solution for an energy-efficient household.
  • Passive Income: If your EV supports V2G, you can partner with an electricity provider that compensates you for supplying energy back to the grid during peak hours. V2G is not just about environmental benefits and reducing energy waste — it’s also an opportunity to generate income. According to some estimates, an EV with V2G capability could save you around $15,000 over a 10-year period. It’s a perfect example of how “cash-back” and “energy-back” go hand in hand.
  • Reducing Emissions: If the majority of EVs adopt V2G technology and return energy during peak demand, it could significantly lower energy production requirements, ultimately leading to a substantial reduction in carbon emissions. Who knows — could V2G be a key factor in combating global warming?
  • Reducing Reliance on Charging Stations: As V2V technology advances to enable charging speeds comparable to traditional charging stations, EV owners could assist others in urgent need of a quick recharge. Imagine helping a fellow driver by letting them draw energy fr om your car, allowing them to reach their destination safely. V2V technology has the potential to foster a stronger, more supportive community among EV drivers.
  • Reimagining EV Utility: Bidirectional charging technology has transformed EVs fr om simple vehicles into versatile power banks for all your electric appliances. Whether it’s powering a coffee machine or operating specialized work equipment, V2L provides a reliable energy source to meet your diverse needs.

While bidirectional charging is a promising technology, its development is still in its early stages and faces several hurdles. In this section, we’ll explore the primary challenges that must be resolved to ensure its successful implementation and to minimize potential complications:

  • Lack of Necessary Equipment: Currently, the market offers a limited selection of bidirectional chargers capable of transferring energy fr om EVs to buildings and grids. Additionally, only a small number of EVs support even basic V2L technology, let alone more advanced V2H and V2G capabilities. However, it’s important to recognize that this is merely a matter of time.
  • Establishing Proper V2G Usage Practices: While many automakers are actively testing V2G technology, the key challenge lies in defining how owners will manage its functionality. A critical issue is preventing situations where energy is being transferred back to the grid, and the owner suddenly needs to use the vehicle. The solution seems clear: before initiating energy transfer, the owner must be informed of the exact start and finish time and how much energy their EV will lose once the process is complete.
  • The High Price of Progress: Like most emerging technologies in the EV world, bidirectional charging comes with a hefty price tag. For this technology to revolutionize the EV industry, automakers must integrate advanced bidirectional on-board chargers into their vehicles, EV charger manufacturers must replace outdated infrastructure with new bidirectional chargers, and utility companies must upgrade power grids to handle energy flow from chargers. Although these efforts require substantial resources, the long-term environmental impact justifies the expense.

In this section, we’ve compiled a list of EVs that currently support bidirectional charging. Since some automakers have multiple models with this capability, we’ve organized the section by brand or concern, detailing specific models under each automaker. Let’s explore which EVs are paving the way for progress in this field:
