Types of EV Bidirectional Charging: Definitions and Key Differences

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.

V2L (Vehicle-to-Load)

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?

V2H (Vehicle-to-Home)

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.

V2G (Vehicle-to-Grid)

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.

*V2X (Vehicle-to-Everything)

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.

Main Benefits of EV Bidirectional Charging

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:

Challenges and Limitations

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:

EVs Supporting Bidirectional Charging

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:

Nissan

Surprisingly, one of the most established and popular EVs, the Nissan Leaf, features bidirectional charging capabilities, allowing it to support both V2G and V2H applications. Another promising model from Nissan is the Ariya, which, according to our sources, is already equipped with a bidirectional charger capable of supporting V2G and V2H. However, its functionality remains inactive for now, as Nissan has yet to enable it via a software update.

Zhejiang Geely Holding

This major Chinese auto conglomerate offers a variety of EVs with bidirectional charging capabilities. Polestar’s latest models, including the Polestar 3 and Polestar 4, are fully compatible with V2G, V2H, and V2L technologies. The older Polestar 2 currently supports only V2L, though future software updates may enable additional capabilities. Volvo has also begun incorporating bidirectional charging in its newest models, such as the EX30 and EX90, both of which support all three types. Meanwhile, Zeekr, a new brand expanding into Europe, offers the models X and 7X, which supports V2L technology only.

Volkswagen Group

Currently, Volkswagen Group offers full bidirectional charging for all EVs equipped with the 77 kWh battery. If you prefer a Volkswagen, you can choose from models like the ID.3, ID.4, ID.5, ID.7, and ID.Buzz. For other brands within the group, Cupra provides the Tavascan SUV and Born hatchback, Škoda offers the Enyaq and the smaller Elroq, while Audi presents the Q4 e-tron SUV. In the future, we hope bidirectional charging functionality will expand to more trims and battery capacities, giving customers greater flexibility.

Hyundai Motor Group

This Korean automotive giant was one of the pioneers in incorporating V2L technology into its EVs. The group’s most advanced models — Kia EV9, Kia EV3, and Hyundai Ioniq 9 — support V2G, V2H, and V2L technologies (while we are not entirely certain about the Ioniq 9, it is likely to share the same technology as the EV9). Other models in the lineup currently feature V2L functionality. Kia offers the Niro EV and EV6, with hopes that the refreshed EV6 will support V2X. Similarly, Hyundai’s Ioniq 5, Ioniq 6, and Kona Electric support V2L, as does Genesis with its GV60, Electrified GV70, and Electrified G80.

Ford was one of the first automakers to highlight V2H technology, debuting it with the F-150 Lightning. This model supports V2L and V2H charging, with V2G expected to follow, though it hasn’t yet been validated in real-world tests. Meanwhile, in Europe, Ford’s Capri EV and Explorer EV include V2X capabilities in sel ect trims, thanks to the integration of VW’s 77 kWh battery.

Tesla

GM is actively competing in the bidirectional charging space. Chevrolet already offers several EVs with V2X capability or plans to introduce it soon, including the Silverado EV, Equinox EV, and Blazer EV. Cadillac’s entire lineup — Lyriq, Vistiq, Escalade IQ, and Optiq — also supports V2X charging. However, it's important to note that the Lyriq will only feature bidirectional charging in models produced from onward, meaning older versions may lack this functionality. GMC is also embracing this technology with the Sierra EV and Hummer EV (Pickup and SUV). Similar to the Lyriq, the Hummer EV is expected to offer bidirectional charging from , but only when equipped with the optional 19.2 kW on-board charger — though details remain unconfirmed.

BYD

At the end of , Renault introduced the 5 E-Tech, its first model with full V2X capability. In , the brand will expand this technology to the Renault 4 E-Tech, which will feature the same bidirectional on-board charger. As for other models like the Scenic E-Tech and Megane E-Tech, we are still awaiting official confirmation regarding their compatibility. Many hope that a simple over-the-air update will unlock these capabilities.

Stellantis
