V2L vs V2H vs V2G: Using Your EV as a Battery, Explained

Modern EVs carry a large battery, and increasingly that battery can do more than move the car. Three related ideas describe this: V2L, V2H and V2G. They sound similar but differ a lot in what they can power, what equipment they need, and how available they are in the Philippines today. This guide explains each in plain terms so you can tell marketing claims from what you can actually use now.

What do V2L, V2H and V2G actually mean?

All three let your car send energy out rather than only take it in. The difference is where that energy goes.

• V2L (vehicle-to-load). The car powers appliances directly through a socket or adapter, much like a large portable power station. This is the most common and simplest form available today.
• V2H (vehicle-to-home). The car back-feeds your house, so your lights and outlets can run from the car during an outage. This needs dedicated equipment that connects the car to your home wiring safely.
• V2G (vehicle-to-grid). The car sends energy back to the public grid, in principle letting you support the network or earn from stored energy. For most drivers this remains largely future-facing and limited.

What does each one need?

The gap between the three is mostly about hardware and approvals.

• V2L needs the least. If your EV supports it, you usually plug an adapter into the car and run appliances straight away. Confirm that your specific model and port support it, and that the appliances you want to run fall within the limits the maker states.
• V2H needs proper installation. Back-feeding a house safely means a compatible car, suitable equipment, and wiring that keeps the car and the grid from ever clashing. Treat this as an electrical project and talk to a licensed electrician; our guide to home charger electrical requirements covers the kind of checks involved.
• V2G needs the most, including the grid side. Beyond special hardware, it depends on your utility and the rules allowing two-way energy flow and settling how you are credited. That framework is still developing in many markets.

What is realistic in the Philippines right now?

Here is the honest picture, which you should always confirm against your own car, your electrician and your utility.

• V2L is the practical one today. If your EV has it, you can run a fridge, fans, lights or tools during a brownout without any grid approval. Our V2L brownout guide walks through doing this safely.
• V2H is possible but involved. It depends on having compatible equipment and a safe installation, so it is realistic for some households but not a plug-and-play option. Confirm feasibility and cost with your electrician before counting on it.
• V2G is mostly future-facing here. Widespread vehicle-to-grid needs supportive grid rules and tariffs that are not broadly in place, so treat any earnings claims with caution and verify the current position with your utility.

Which one should you plan around today?

For most Filipino drivers, V2L is the feature to look for and use now; V2H is worth planning if you want whole-home backup and are ready for an installation; V2G is something to watch rather than rely on.

• Check the port and connector. Whether a car supports V2L, and through which plug, varies by model; our connectors guide explains the common types.
• Match it to your real need. Powering a few appliances in a brownout is very different from backing up an entire house.
• Verify before you buy. Confirm any power figure, limit or earning claim with the carmaker, your electrician or your utility rather than taking a brochure at face value.

Frequently asked questions

Is V2L the same as powering my whole house?

Not quite. V2L powers appliances you plug into the car, like a large portable power station, while powering your whole house through its wiring is V2H and needs dedicated equipment and a safe installation. Confirm what your model supports with the maker and a licensed electrician.

Can I sell energy back to the grid in the Philippines?

For most drivers, not in a practical, widespread way yet. V2G depends on grid rules, equipment and tariffs that are still developing, so treat any income claims cautiously and check the current rules with your utility.

How much can V2L actually run?

It depends on your car, its port and the appliance limits the maker states, so there is no single answer. As an illustration only, people often run essentials such as a fridge, lights and fans; always check your model's stated limits before relying on it.

Do I need an electrician for V2L?

For simply plugging appliances into the car, usually not. But if you want the car to back-feed your home wiring, that is V2H, which is an electrical project where you should involve a licensed electrician.
