There's a lesser-known, but increasingly popular, functionality that electric vehicle buyers should consider: bidirectional charging. This capability allows an EV to act as a battery and power your home, appliances and more. As of , bidirectional charging is available with an increasing number of cars, including the Ford F-150 Lightning and the Nissan Leaf. This feature is continuing to grow in popularity, with GM announcing last year that the technology will come standard in all its electric vehicles by model year .

Typically, EV charging is a one-way process: Alternating current electricity -- the kind that comes from a wall socket -- is sent from an EV charger, outlet or other power source to a car's battery, where it's converted into direct current energy.
Bidirectional charging allows the vehicle to convert stored DC energy back into AC electricity for a variety of uses.
Depending on the setup, the power stored in the battery can be used in different ways:
Vehicle to home: V2H, also known as vehicle to building (V2B), this functionality allows your car to serve as a backup generator during a power outage. A fully charged EV battery holds about 60 kilowatt-hours of electricity on average, enough to power a home for two days.
With smart-charging technology, you could also use V2H tech to lower your energy bill by charging your EV during off-peak hours and powering your home when prices are higher.
Vehicle to grid: A vehicle with V2G charging capability can send electricity back to the utility network, just like homeowners with solar power can do. Not only are you helping stabilize the grid, but you also get paid for the energy you provide.
An EV owner with a V2G charger could save up to $150 per year on their electricity bill, according to data from the University of Rochester.
Vehicle to load: V2L is the most basic type of bidirectional charging. Typically, an adapter is all you need for your car to power camping equipment, power tools, home appliances or other standalone devices.
Vehicle to vehicle: Another form of V2L, V2V allows EV owners to provide power to an EV that's run out -- similar to giving a "jump" to a gas-powered automobile.
Vehicle to everything: V2X is an umbrella term that encompasses all bidirectional charging options.
As of , only certain EVs sold in the US offer any form of bidirectional charging, though more are expected to be on the road in . They will include:
While bidirectional functionality is by no means universal, automakers are swiftly adding it to their lineups to meet demand and potentially get ahead of regulators.
BMW, Volvo and Porsche are all reportedly testing functionality. Tesla has said all of its models will support bidirectionality by .
General Motors started making V2H charging a default feature in , starting with the Chevrolet Silverado EV RST. The GM rollout continued with the GMC Sierra EV Denali Edition 1, Chevrolet Blazer EV, the Chevrolet Equinox EV, the Cadillac Lyriq and the Escalade IQ, Cadillac's first full-size all-electric SUV. In and beyond, we're expecting the GMC Sierra EV Denali Edition 1, Cadillac Lyriq, Cadillac Escalade IQ, Cadillac Optiq and more.
Ram also launched its first vehicle with bidirectional charging in , with the Ram REV electric truck now expected to launch in .
The automotive industry is undergoing a significant transformation with the rapid rise of electric vehicles (EVs). As more consumers and companies shift toward cleaner transportation options, the demand for efficient and high-performing components has increased—especially for wiring and cable systems that support these vehicles.

The shift to EVs has led to significant developments in the types of components used in automotive design, particularly when it comes to wiring and cables. The wiring system in an electric vehicle plays a crucial role in everything from power distribution to safety. Whether you’re a manufacturer, supplier, or EV owner, understanding the ins and outs of EV wiring can help ensure performance, longevity, and safety.
Let’s explore the key aspects of wiring in electric vehicles, from the types of cables used to critical considerations for ensuring optimal performance.
In a traditional internal combustion engine (ICE) vehicle, wires and cables are primarily used for distributing electrical power to various systems like lighting, infotainment, and power accessories. However, in an electric vehicle, the wiring system serves a much more crucial function—it’s responsible for distributing the high-voltage electricity from the battery to the electric motor, as well as to auxiliary systems like the climate control and regenerative braking systems.
In addition to managing higher power loads, EV wiring must handle increased complexity as these vehicles often come equipped with advanced electronics, sensors, and communication systems that work together to ensure smooth, efficient, and safe operation.
An electric vehicle’s wiring system comprises several essential components that work in unison to power the vehicle, manage data, and ensure the overall safety of the car. The following are some of the most critical wiring components in an EV:
High-voltage cables are the backbone of an electric vehicle. These cables are responsible for transferring electricity from the battery to the electric motor and various systems throughout the car. Given the significant amount of energy being transported, these cables must be designed to withstand high temperatures, resist wear and tear, and maintain reliability over time.
The primary challenge with high-voltage cables is ensuring they remain safe even in extreme conditions, such as during accidents or under intense load. For this reason, these cables are often designed with high-quality insulation, shielding, and are subject to strict safety standards and certifications.
Even though electric vehicles are powered by high-voltage batteries, low-voltage wiring is still required for essential systems such as lighting, infotainment, and basic vehicle controls. These low-voltage systems typically operate at 12V or 48V and are separate from the high-voltage system that powers the drivetrain.
Just like in conventional vehicles, low-voltage wiring needs to be lightweight and flexible, making it easier to route through tight spaces. Given that EVs are typically lighter than their ICE counterparts, manufacturers are increasingly turning to lightweight materials for wiring to optimize efficiency and range.
Low-voltage cables also play a critical role in electric vehicle (EV) charging stations, facilitating essential communication, control, and safety functions during the charging process. While high-voltage cables transfer electricity from the charging station to the vehicle, low-voltage wiring handles the interaction between the station and the EV, ensuring safe and efficient charging.
Electric vehicle charging stations require robust wiring to handle the high current and voltage necessary to charge EVs efficiently. Depending on the type of charging station (Level 1, Level 2, or DC fast charging), the wire and cable specifications will vary.
Level 1 charging stations are typically used for home charging and are the slowest type of charging available. They use standard household outlets (120V AC) and require minimal specialized wiring.
Level 2 charging stations are the most common for both residential and commercial use. They operate at 240V AC and can charge an electric vehicle in a fraction of the time required by a Level 1 charger.
DC fast chargers (also known as Level 3) are the most powerful and are typically found in commercial or public charging stations. These systems bypass the vehicle's onboard charger and deliver DC power directly to the battery, allowing for much faster charging.
Wiring for electric vehicles is far more complex than for traditional gas-powered cars. Here are some of the most common challenges manufacturers and engineers face:
To ensure safety and reliability, EV wiring must adhere to a variety of standards and certifications. Common standards include:
Compliance with these standards ensures that the cables used in EVs are resistant to factors like extreme temperatures, chemicals, and mechanical stress.
Wiring is a critical component of electric vehicles, playing a key role in power distribution, safety, and the overall performance of the car. From high-voltage cables that deliver power from the battery to low-voltage systems that manage everything from lighting to infotainment, EV wiring systems are designed to handle complex demands. As technology advances and electric vehicles become more commonplace, innovations in wiring materials and designs will help make EVs even more efficient, durable, and safe.
For anyone involved in the electric vehicle industry, whether as a manufacturer, supplier, or consumer, understanding the role of wiring systems is essential to ensuring the ongoing success of EV technology.
