Using Your EV for Site Power and Power Tools (V2L)

Vehicle-to-Load (V2L) turns a capable electric vehicle into a mobile power source for tools and site equipment, with no generator needed. If your car has V2L and you pair it with a CEE 16A V2L cable, you can plug a site extension lead, a temporary distribution board, or a power tool directly into the car and draw real 230V mains-style power wherever the car can park. It is a practical solution for tradespeople, small builders, outdoor events, and anyone who needs temporary power away from a fixed supply. The V2L discharge cables page has the cables to make it happen.

What is the actual power limit for site use?

The limit is your car's V2L output rating, not the cable. Most V2L-capable cars on the UK market output roughly 3.6kW, which translates to around 16A at standard UK mains voltage. That is the same level as a typical campsite hookup or a standard single-phase ring circuit, and it is enough to run most hand tools and light site equipment comfortably. The key watchpoint is start-up or peak current: many electric motors draw two to three times their running current at start-up, so a tool rated at 1,000 watts running might briefly demand significantly more at switch-on. Add headroom when adding up your expected loads, and check your car's V2L output specification with the manufacturer for the exact figure.

How do you connect site tools to a V2L car?

For tools with standard 3-pin plugs, you have two options. You can use a 3-pin V2L cable directly and plug tools into a standard socket, or you can use a CEE 16A V2L cable with a site extension lead that runs from the CEE socket to a standard multi-socket extension reel. The CEE 16A option is often better for outdoor site work because the connector is weatherproof and more robust than a standard 3-pin connection in wet or dusty conditions. Do not use domestic extension leads that are not rated for outdoor or site use; choose extension equipment rated for the job.

Setting up with a CEE 16A V2L cable

• Activate V2L mode on the car following the manufacturer's procedure
• Connect the CEE 16A V2L cable to the car's V2L port
• Connect a site-rated extension lead with CEE 16A input to the V2L cable's output socket
• Plug tools into the extension lead's 3-pin sockets
• Start tools one at a time to manage start-up current peaks
• Monitor the car's displayed V2L load or state of charge

Is it safe to run power tools through V2L outdoors?

Yes, with the same precautions that apply to any outdoor site power supply. Use extension leads and equipment rated for outdoor or site use, not domestic extension reels. The CEE IEC 60309 connector is weatherproof when properly mated, which is one reason it is the preferred connector for site power. Ensure that any extension equipment has appropriate overcurrent protection: site-rated extension leads typically include RCD protection, which trips the circuit if a fault or shock risk is detected. Keep connections off wet ground where practical, and inspect cables for damage before each use. Do not run tools in excess of the car's V2L output rating.

How long can you run tools from the EV battery?

Duration depends on the car's battery capacity and the average power draw of the tools in use. Light, intermittent tool use draws far less over a working morning than continuous heavy-load tools. There is no single figure that applies to all cars and all tools, and we would rather not invent one. What we can say is that V2L is best suited to tasks where tool use is intermittent rather than continuous, and where the job can be completed within a session before the car needs to drive elsewhere. Monitor the car's state of charge and plan to leave enough charge in reserve to reach the next charging point. For all-day heavy site power, a dedicated generator or mains supply remains the more practical option.

What are the advantages over a petrol generator?

Using the car's V2L output instead of a generator removes the need to carry, store, refuel, and maintain a separate machine. There are no fuel costs on the day, no exhaust fumes, and significantly less noise, which matters on residential sites, in gardens, and at events where noise restrictions apply. The car is already there; the only additional equipment is the cable. The trade-off is that you are drawing down the car's battery, which needs recharging afterwards. For intermittent and light-to-medium power needs, V2L is often the more convenient and less costly option. For sustained heavy power draws over a full working day, a dedicated generator may still be the right tool.

Which cars support V2L for site power use?

V2L is available on a range of modern EVs, with common examples including various Kia, Hyundai, and MG models. Availability varies by model and trim level, so do not assume all versions of a given car include it: check the specification for your exact model and year. The car must have the V2L feature built in for any V2L cable to work. Some vehicles offer V2L through a dedicated port, while others use the charge port with a specific adapter. Check your owner's manual or ask the manufacturer for your vehicle's V2L setup.

Frequently asked questions

Can I run two or three power tools at the same time through V2L?

Potentially, if their combined continuous wattage stays within the car's V2L output rating. In practice, running multiple tools simultaneously risks exceeding the limit, particularly at start-up. Start tools one at a time and monitor load. If the car's protection cuts in, reduce the number of tools in use. Running one tool at a time is the safest approach when close to the output limit.

Do I need a site extension lead rated for 16A or just a standard extension reel?

For outdoor site use, always use a lead rated for outdoor or site conditions. Standard domestic extension reels are not designed for site environments. A site-rated lead with CEE 16A input and standard 3-pin sockets is the appropriate equipment when using a CEE 16A V2L cable for tool power. It also typically includes RCD protection, which is important for safety outdoors.

Will high-draw tools damage my EV's V2L system?

The car's V2L inverter has built-in protection circuitry. If the load exceeds the rated output, the inverter cuts the supply rather than allowing damage. No damage occurs from the protection triggering. Simply reduce the load and reactivate V2L mode. Sustained operation at the very top of the inverter's limit is not ideal in the long term, but occasional spikes or protection trips during normal tool use are not harmful.

Is there a risk of starting-current spikes tripping the V2L protection frequently?

It is possible with tools that have high start-up current relative to their running draw. Starting tools one at a time rather than simultaneously reduces the risk. Some V2L inverters handle brief start-up spikes tolerantly; others are more sensitive. If a particular tool consistently triggers the protection at start-up, check its start-up current rating and compare it with your car's V2L specification.

Can I use a standard domestic extension lead with a CEE 16A V2L cable?

You would need an adapter to mate the CEE 16A socket with a standard 3-pin plug on a domestic lead. This is possible, but for outdoor and site use, a proper site-rated extension lead with CEE input is the better and safer choice. Domestic extension leads are not designed or rated for wet or site conditions.

Does using V2L void my EV's warranty?

For cars where V2L is a manufacturer-supported feature, using it as intended should not affect the warranty. V2L is documented and enabled by the manufacturer in these vehicles. However, warranty terms vary by manufacturer, so if you have concerns, check with your dealer or the manufacturer directly before regular heavy V2L use.

If you are ready to use your EV as a site power source, the V2L discharge cables collection has the cables for CEE 16A and standard 3-pin outputs in various lengths. For general guidance on EV charging cables and accessories, our guides section covers the topics UK EV drivers ask about most.
