One of the most common questions asked by new Tesla owners is whether it’s ok to charge a Tesla in the rain.
From a young age, we all learn that electricity and water are a dangerous combination, so it’s no surprise that people worry about plugging an electric vehicle into a charger while standing outdoors in wet weather.
But is there really any cause for concern? Let’s find out more about charging a Tesla in the rain and how different types of chargers handle rainy conditions.
Charging a Tesla in the rain
If you’re using a Tesla Wall Connector or a Supercharger then – as long as there isn’t water inside the connector – it is perfectly safe to charge your Tesla in the rain.
However, if you’re using a Gen2 Mobile Charger, which plugs into a normal wall socket, then it is best to charge your Tesla indoors or in dry conditions only.
Using a Tesla Wall Connector in the rain
The Tesla Wall Connector uses a NEMA 3R fitting, which is weather resistant. It can therefore be installed indoors – usually inside a garage – or outdoors if you prefer.
As long as you get your wall connector installed by a qualified electrician, it will be safe to use in dry weather, rain, or snow.
The only precaution you should take is to always store your connector with the plug hanging down towards the ground. The reason for this is to stop rainwater from getting inside the connector.
If you think water may have got inside your Tesla Wall Connector for any reason then you should wait for it to dry out before charging.
Using a Tesla Supercharger in the rain
Like wall connectors, Tesla Superchargers are also perfectly safe to use in rainy weather.
When you plug the supercharger into your car, your Tesla will run a series of safety checks. You will know that these are complete when you see a green light appear on the charging port. Your car will only begin charging once the onboard computer has determined that there is a safe connection.
There’s only one time that we would advise against using a supercharger in the rain, and that’s when there is a thunderstorm.
Tesla has worked to prevent battery damage in the event of lightning strikes, and damage is unlikely. But there is still some risk.
It’s up to you whether you think it is worth taking a chance and using a supercharger in a thunderstorm, but just to be on the safe side, we would suggest waiting if you possibly can.
Using a Tesla Gen2 Mobile Charger in the rain
The Gen2 Mobile Charger is the standard charging cable that you get when you buy a Tesla. It plugs into a normal wall socket and is therefore perfectly suited to charging inside a garage.
However, if you don’t have a garage, or you want to charge your Tesla outdoors, you will need to plug the charger into a weatherproof outdoor socket.
This is where you need to be careful and get help from a qualified electrician.
Tesla’s recommendation is that your weatherproof outdoor socket should be positioned at least 18 inches above the ground. This minimizes the risk of the socket being submerged in water or snow.
The company also warns drivers not to charge their Tesla using a Gen2 Mobile Charger when the charger or the car is wet or when it is raining heavily.
If you’re using a Tesla Wall Connector or a supercharger then it’s perfectly safe to charge your vehicle in the rain, but if you are using a Gen2 Mobile Charger, we highly recommend waiting for the weather to dry up.
