Which Electric Vehicles Offer Bidirectional Charging in 2024?

Bidirectional charging transforms an electric vehicle from a simple mode of transport into a mobile power source, capable of powering your home, appliances, or even sending electricity back to the grid. While still an emerging technology, this capability is available today on select models from Ford, Hyundai, Kia, Nissan, and others, with more automakers planning to integrate it soon. This guide breaks down how it works, the different types available, and which EVs currently offer this game-changing feature.

What is Bidirectional Charging and How Does It Work?

Most electric vehicles use unidirectional charging, a process where Alternating Current (AC) electricity from the grid is converted to Direct Current (DC) to charge the car's battery. Bidirectional charging, however, turns this into a two-way street. It allows DC power from the vehicle's battery to be converted back to AC through a dedicated charger or an inverter within the vehicle itself. This enables electricity to flow not just into the car, but also out of it, providing power to a home, the grid, or other devices. Based on our assessment experience, this technology is poised to redefine the relationship between drivers, their vehicles, and their energy consumption.

V2G, V2H, V2L: What Do These Acronyms Mean?

Understanding the types of bidirectional charging is key to knowing how you can use it. The technology is generally categorized into three main types:

• Vehicle-to-Grid (V2G): This system allows an EV to supply electricity back to the local power grid. This can help balance energy demands during peak usage times and could potentially allow owners to earn credits or payments from utility companies.
• Vehicle-to-Home (V2H): V2H capability uses the EV's battery to power a house. This can act as a backup generator during a power outage, lessening demand on the grid, and may offer savings by powering the home during peak hours when electricity rates are highest.
• Vehicle-to-Load (V2L): The most accessible form, V2L allows the vehicle to power appliances and electronic devices directly via built-in or accessory power outlets. Unlike V2G and V2H, V2L typically does not require a dedicated bidirectional charger.

Which Electric Vehicles Have Bidirectional Charging Today?

The list of EVs with bidirectional charging is growing. Here are the key models available in 2024.

Ford F-150 Lightning The F-150 Lightning offers a robust Vehicle-to-Home (V2H) system called Intelligent Backup Power. With an available 80-amp home charger and up to 131 kilowatt-hours (kWh) of storage, Ford estimates it can power an average home for up to three days on a normal charge.

Hyundai, Kia, and Genesis Models like the Hyundai Ioniq 5 & 6, Kia EV6 & EV9, and Genesis GV60 currently feature Vehicle-to-Load (V2L). Their shared platform can supply up to 3.6 kW of power through a built-in outlet, enough to run appliances while camping or during a short outage.

Nissan Leaf As a pioneer, the Nissan Leaf offers Vehicle-to-Everything (V2X) capability, meaning it can provide power to your home, the grid, or another EV. This requires a compatible external device to function.

Volkswagen ID.4 For the 2024 model year, VW introduced bidirectional charging. Currently, only ID.4s with the 77-kWh battery pack and the latest software can provide V2G and V2H capabilities.

General Motors (GM) EVs GM offers a V2H Enablement Kit for its Ultium-platform vehicles like the Chevrolet Silverado EV, Blazer EV, and Cadillac Lyriq. This system, which requires separate purchase and installation, is designed to power a home for an extended period.

Other Notable Models

• Tesla Cybertruck: Offers a comprehensive suite including V2H, V2L, and Vehicle-to-Vehicle (V2V) charging.
• Lucid Air: Features a unique "RangeXchange" function for V2V charging.
• Jeep Wrangler 4xe (PHEV): This plug-in hybrid offers V2L capability through an accessory called the Mopar Power Box.

What is the Future of Bidirectional Charging?

The future direction is Vehicle-to-Everything (V2X), which integrates all bidirectional charging types. Automakers like Ford, GM, and Volkswagen are actively part of industry coalitions to develop the necessary infrastructure. As Sam Fiorani, Vice President at AutoForecast Solutions, notes, “By the end of this decade, this will be the norm rather than a special feature. EVs will become more integrated into owners’ lives just as their phones have.”

Bidirectional charging adds significant value to EV ownership, providing energy security and potential cost savings. When considering an EV, assessing its bidirectional capabilities—whether V2L, V2H, or V2G—is a crucial step, as the required equipment can vary in cost and complexity.
