How to Power a Caravan or Campervan From Your EV

If your electric vehicle has Vehicle-to-Load (V2L), you can power a caravan or campervan from the car's battery using a CEE 16A V2L cable: a short lead that plugs into your car's V2L port on one end and presents a blue IEC 60309 commando socket on the other, the same socket that every caravan hookup lead terminates in. It takes roughly the same effort as plugging into a campsite pedestal. The V2L discharge cables range includes the cables you need, in various lengths to suit your setup.

Does my car need to be running to power the caravan?

No. EVs have no engine to run, so V2L operates with the car parked and stationary in its dedicated V2L mode. You typically activate this through the car's infotainment or settings menu. The car manages its own battery and protection systems throughout. The exact activation steps vary by make and model, so refer to your owner's manual for the correct procedure for your vehicle. Once active, the car supplies AC power to the cable just as a campsite pedestal would.

What caravan equipment can the EV actually run?

The honest answer depends on two things: your car's rated V2L output and your caravan's appliance loads. Most V2L cars output roughly 3.6kW, which is comfortably above the sort of power draw a typical touring caravan creates when running sensibly. You can generally expect to run caravan lighting, a compressor fridge, phone and tablet charging, a television, and modest fans or ventilation. A kettle is a heavy draw and will likely occupy most of the available output on its own, so treat it as a single task. An electric shower or large immersion heater will likely exceed the available power. Always add up the wattage of everything switched on at once and compare it to your car's rated V2L output, which you can find in the owner's manual or by asking the manufacturer.

How long will the EV battery last powering the caravan?

This depends on your battery capacity and the total load. A light caravan setup drawing only lighting and a fridge will consume far less over an evening than a heavier setup with a kettle and television running frequently. There is no single answer, and we would rather not invent a figure. What we can say is: monitor the state of charge on the car's display, plan your usage around how much charge you need to complete the drive to your next charging point, and keep enough in reserve. V2L is best thought of as a convenient supplement to campsite hookup power, not an alternative to charging the car.

Is a special hookup lead needed, or will my existing one work?

Your existing caravan hookup lead will work provided it is in good condition and correctly rated. The blue CEE 16A socket on the V2L cable is the same connector that campsite hookup pedestals use, so you do not need any new equipment on the caravan side. Inspect the hookup lead before use: check for damage to the cable insulation, make sure the plug and socket are clean and dry, and ensure the lead is not coiled tightly under load, as this can cause it to heat up. Standard caravan hookup leads include RCD protection, which is good practice for outdoor circuits.

Are there any safety points specific to using V2L with a caravan?

Common-sense rules apply. Keep the CEE connection point out of standing water and shelter it where practical: the CEE connector is weatherproof when mated, but do not leave the socket uncovered in rain. Do not exceed your car's V2L output rating by running too many appliances simultaneously. If the car's system cuts out, it is usually because the load exceeded the inverter's limit or a protection threshold was reached: reduce the load before reconnecting. Do not leave a high load running unattended for extended periods without checking both the car's state of charge and the condition of the connections.

Can I use V2L as a full replacement for campsite hookup power?

Practically, V2L from your car is most useful as a backup or supplement to a campsite hookup rather than a primary replacement for it. The car's battery is finite, and you will need charge to drive on afterwards. On a campsite with a hookup point, there is little reason to use the car's battery when mains hookup is available and usually cheaper. Where V2L shines is on wild camping trips, in a field without hookup, at a festival, or in a situation where no mains supply is available. In those contexts, V2L genuinely replaces what a generator would otherwise provide.

Frequently asked questions

Do I need a special cable to connect my caravan to an EV's V2L output?

Yes. You need a CEE 16A V2L cable that matches your car's V2L port on one end and provides a blue CEE IEC 60309 socket on the other. Your caravan's existing hookup lead plugs into that socket. The cable must be compatible with your specific car's V2L port, so check compatibility before purchasing.

Can I use V2L without my EV being plugged in to charge at the same time?

In most cases, yes. V2L typically operates from the car's battery in a dedicated stationary mode, independent of charging. The car will draw from its own battery to supply power to the caravan. You cannot generally charge the car and run V2L simultaneously, so plan your usage and charging stops accordingly.

Will running V2L damage my EV battery?

Normal V2L use within the car's rated output will not damage the battery. The car's own management systems protect the battery and will cut off the V2L supply before the battery reaches a critically low level. Repeated deep discharge cycles over long periods are not ideal for any battery, but occasional V2L use for camping is well within normal operating parameters for a modern EV battery.

Does V2L work with motorhomes as well as caravans?

Yes. A motorhome uses the same blue CEE 16A hookup inlet as a caravan, so the connection is identical. The same cable and the same process apply. As with caravans, check the motorhome's total appliance load against the car's V2L output rating before switching everything on.

What happens if I try to run too many appliances through V2L?

The car's V2L inverter has built-in protection. If the connected load exceeds the rated output, the inverter will typically cut power automatically, similar to a circuit breaker tripping. Reduce the load by switching off some appliances and then reactivate V2L mode. No damage is caused by this protection triggering.

How do I know what my car's V2L output rating is?

Check the owner's manual or the manufacturer's specification sheet for your specific model and year. You can also contact your dealer or the manufacturer's customer support. The rated V2L output is the ceiling for everything connected through the cable, so knowing this figure before you start is important for planning what you can safely run.
