Yes, you can charge an electric car in the rain, and in the snow too. Charging plugs and chargers are built for outdoor use, and no power reaches the plug until the car and the charger have checked each other.
## Why rain is not a problem

When you plug in, power does not start flowing straight away. The charger and the car first exchange information: is the plug seated properly, is the earth connection fine, how much power may flow through the cable? Only then does the contact close. If nothing seems to happen for a few seconds after plugging in, that check is running.

If something goes wrong during charging, such as a leak to earth, the installation switches off. A home wallbox also has the earth leakage protection in your fuse box. An ordinary shower does not defeat that system.

The charging port on your car is made for outdoor use too. A few drops when you plug in are no reason to worry.

## How to charge on a wet day

1. Check that the cable and plug are intact before you pick them up. Cracks, melted spots or exposed wires mean you should not use them. What to do next is covered in [broken charger](/en/blog/broken-charger-what-to-do/).
2. Wipe or shake the worst of the water off the plug. It does not need to be bone dry.
3. Push the plug straight into the port until it clicks, and wait for the car or the app to confirm that charging has started.
4. Do not leave the cable in a puddle. Hang it on the charger's holder, or lay it so it stays above the water.
5. End your session through the car, the app or the charger before you unlock the plug. That way the cable is definitely no longer live.

Do you use a charging card, or pay on the spot with your bank card? Do it under a canopy or from inside the car if you can, so the charger's screen does not take the full downpour. It is simply easier with dry fingers.

## During a thunderstorm

The chance of lightning hitting your charger is small. Even so, a strike nearby can cause a surge on the grid, and that can damage the electronics in a wallbox or a car. If the storm is right overhead, postpone charging.

A worked example: you need 30 kWh and the charger delivers 11 kW. That is 30 divided by 11, so about 2.7 hours of charging. If you wait half an hour for the storm to pass, you miss 11 x 0.5 = 5.5 kWh, which you top up later.

## Frost and snow

In frost, a plug or charging flap can freeze shut. Do not pull or pry. First try to unlock the plug from the car, wait a few minutes, or gently thaw the flap with your hand or a towel. Do not use a knife or scraper, as that damages the seal. Brush snow off the charging port before you open the flap so nothing falls in.

## When it is different

This all applies to a normal charging cable and a charger or wallbox that works properly. It does not apply to:

- an emergency cable or extension lead in an outdoor socket. Water and a socket that delivers a lot of power for hours are a bad mix, see [emergency cable and wall socket](/en/blog/emergency-cable-wall-socket-risks/)
- a cable or plug that is damaged, repaired with tape or missing part of its housing
- a car or charging spot that is under water after a flood. Touch nothing, do not charge, and call an installer or the emergency services if it looks dangerous
- a plug with dirty or scorched pins, even if it is dry

## A wallbox outdoors

If your wallbox hangs outdoors, its specifications show an IP code. The second digit tells you how well the unit is protected against water: the higher, the better. Choose a model that is explicitly meant for outdoor use, and have it fitted and inspected by an approved installer. A wallbox under a canopy or on a sheltered wall also wears more slowly.

Store the cable after charging rather than leaving it on the ground. That keeps the plug clean and stops anyone tripping over it. For help choosing, see [how to choose a wallbox](/en/blog/how-to-choose-a-wallbox/), and you can find chargers near you on the [map](/en/map/).
