Vehicle-to-Load and Vehicle-to-Grid Explained: Your EV as a Power Source

V2L, V2H and V2G compared

What bidirectional charging means

Most people think of an EV as something you charge — energy flows in. Bidirectional charging adds the reverse: energy flowing out of the battery to power something else. Because an EV carries a huge battery (often 60-130 kWh, far more than a home battery), it can act as a mobile power station. There are three flavours, distinguished by what the power flows to: a device (V2L), your home (V2H) or the grid (V2G).

V2L: your EV as a giant power bank

Vehicle-to-Load is the simplest and most widespread. It turns the drive battery into a portable power source, delivering mains electricity through a built-in socket (or an adapter on the charge port) so you can run ordinary equipment directly — typically at 3.6-6.6 kW. No extra hardware is needed; it's already in the car.

The uses are genuinely practical:

1. Powering tools on a worksite or in a remote location.
2. Running camping gear — fridge, lights, kettle, devices — for days.
3. Emergency backup for essentials during a power cut.
4. Charging another EV in a pinch, or powering an event.

Because it's built in and easy to use, V2L has become a standard or near-standard feature on many 2026 EVs, led by models like the Hyundai Ioniq range and Kia EVs that popularised it.

V2H: powering your home

Vehicle-to-Home lets your EV power your house — covering essential circuits during an outage, or shifting your home onto battery power during expensive peak hours. The capability can be substantial: the Ford F-150 Lightning leads with 9.6-11.5 kW of export, and the Tesla Cybertruck offers around 11.5 kW. With a large truck battery, that's enough to run a home for a day or more.

The catch is hardware. V2H needs a dedicated bidirectional home charger and the right electrical setup, which adds cost and installation complexity. It's powerful and increasingly available, but it's not plug-and-play the way V2L is.

V2G: selling power back to the grid

Vehicle-to-Grid is the most ambitious: your EV exports power back to the electricity grid, potentially earning you money by selling energy at peak times or providing grid-balancing services. At scale, millions of parked EVs could act as a vast distributed battery, helping integrate renewable energy.

V2G requires the most: a bidirectional charger, a compatible energy tariff and an energy supplier or scheme that supports export payments. It's the least mature of the three and, in 2026, is still limited to specific markets, models and pilot programmes rather than being widely available.

Which EVs support bidirectional charging?

By 2026 most new EVs offer some form of bidirectional capability, with V2L becoming a common standard feature. Full V2H and V2G, however, remain limited to select manufacturers — names regularly associated with it include Ford, Nissan, Hyundai, Kia, BMW and Mercedes-Benz. Because support varies by model, trim and market, always confirm the exact capability (and which of V2L/V2H/V2G) for the specific car you're considering.

Is it worth it?

V2L is an easy yes for many buyers — it's a useful, often-free feature that turns the car into a backup power source for camping, work or outages. V2H makes strong sense if you want home backup or to shift usage away from peak electricity prices, provided you're willing to invest in the charger. V2G is promising but still early; its value depends heavily on local tariffs and schemes, so treat it as an emerging benefit rather than a deciding factor in a 2026 purchase. As ever, check what's actually available in your market before counting on it.
