Is the Tesla Charger Waterproof? Conditions Explained

If you’ve ever been out cruising in your Tesla and then found yourself caught in a rainstorm and losing charge, you may have panicked and wondered if it was safe to charge in the rain. After all, Tesla’s charging voltage is around 400V, which is high enough to be life-threatening! 

Tesla chargers are waterproof and designed in a way that allows you to charge in rain, snow, and dust storms without any harm to yourself or your Tesla. The port can keep water out, so you can charge worry-free, even in heavy rain conditions.

The rest of this article will answer your questions about charging your Tesla and caring for it in all weather conditions. If you want to stay safe and keep your Tesla in good condition, keep reading! 

Can I Charge My Tesla in the Rain?

You can charge your Tesla in the rain. Tesla chargers are waterproof, as they come with a relay that turns on only when it is safe to do so. After plugging in, the charge panel and your Tesla communicate and begin charging when software deems it safe to do so. 

All Tesla Supercharger locations and at-home chargers are safe to use when the weather is wet. 

Short circuits are caused by bad wiring or water leakage. That’s why Tesla chargers have GFCI protected circuits and software that checks for short circuits. If the software detects any moisture or charging issues, the charging stops, and you and your Tesla are safe.

As an added bonus to this article, I’ve created this easy-to-use charging calculator. Simply input your model, charging wattage, and charging percentage, and you will get the estimated time it will take to charge a Tesla in terms of hours. You can play around with numbers a bit just to see how charging time changes:

Tesla wall connectors are also weather-resistant and protect against rain, sleet, snow, and dust. However, it is essential to keep charge ports clean of debris, including snow and water. 

Although this debris might not be hazardous, it will interfere with your charging. That’s because a Tesla charger will automatically shut off if it detects anything in the port.

That means that it is entirely safe to charge in the rain, and you won’t have to worry about anything going wrong. So, next time you need a charge and it’s pouring or snowing outside, just grab your umbrella and plug your tesla in stress-free!

Can I Charge My Tesla During a Thunderstorm?

Tesla advises against charging your Tesla during a thunderstorm. The charger is waterproof and safe from rain, but it is not safe from lightning strikes. 

Tesla chargers can handle the rain of a thunderstorm with no problem. Still, if lightning strikes a power line nearby as you’re charging, the energy could find its way into the car from the power line and damage the electronic circuits inside. 

Just like when you use electronics at home during a thunderstorm, power fluctuations could charge your EV. So, you should avoid charging your vehicle if there is any thunder or rain. 

If you do get caught in a thunderstorm, though, don’t fret! It is safe to sit inside your Tesla in a thunderstorm. Even in the unlikely event of lightning striking the car, you and your vehicle will not be damaged (although your paint job may take a hit).

When you have a Tesla that’s low on charge, try to connect it to a charger before a thunderstorm hits. It’s usually advisable to check the weather before you forgo charging for the day.

Is the Tesla Charging Port Waterproof?

The Tesla charging port is waterproof, but only when you keep it closed. If you leave the port open in the rain or snow, it may not charge the next time you plug it in. 

Since Tesla chargers stop working when they are wet, it’s essential to keep your charging port closed until it’s time to charge. Avoid leaving the port open when it’s raining or snowing, and close it up immediately after you finish your charging session. 

Frequently Asked Questions

What Is a Tesla Supercharger?

A Tesla supercharger is a charger designed for quick charging speeds. Tesla owns and operates a network of over 2,500 superchargers worldwide, and it’s critical only to use a supercharger. 

You can use the map of supercharger locations on the Tesla website or app to find a place, or you can use your in-car navigation system to find the closest station when you’re on the go. 

When you plug in a location for a more extended trip, Tesla’s navigation system includes supercharger locations along the way to ensure you never run out of charge.

These superchargers have the same waterproof qualities and technologies as at-home Tesla chargers and wall adapters. 

How Do You Charge A Tesla? 

To charge a Tesla, park your vehicle next to a supercharger machine and plug it in. After the cable locks into place and the software determines that it is safe to charge, it will deliver power. 

You’ll know it’s working if the logo turns green. 

You can view your car’s charging progress on your Tesla’s central display, which tells you how many more miles you can go and the cost of the charging session. If you leave your car to grab a cup of coffee or a bite to eat while you wait, you can see this information in the Tesla app. 

Your Tesla will charge slower if other vehicles use the same supercharger, but if yours is the only one, it likely won’t take longer than fifteen minutes to get the charge you need. 

However, as with all-electric cars, the charging slows down as the battery level rises.

One benefit of using the supercharger system is that the charging fees automatically bill to your specific Tesla account, so you don’t need to have any cash or credit cards on hand. 

Unfortunately, the price of charging sessions is hard to track because the cost varies by location and time of day.

How Quickly Can I Charge My Tesla?

How quickly you can charge your Tesla depends on your charging level. Superchargers can fill up your battery in about half an hour, but low-volt chargers may take days to charge your vehicle.

Charging Level Charge Time from Empty to Full Miles of Tesla Range per Hour 
Level 1 (120 Volt) 
This level uses a standard 120V electrical outlet
4 days 2 miles per hour of charge 
Level 2 (240 Volt) 
This level uses a 240V circuit, similar to the ones used by dryers and stoves. 
6-30 hours 9-52 miles per hour of charge 
Level 3 (480 Volt) 
This level uses high-power circuits. Superchargers use this level. 
30 minutes Up to 170 miles per 30 minutes of charge 
The table outlines Tesla’s Charging Levels in detail.

This table explains the different charging levels available to Tesla owners, how long it would take to get a full battery per level, and how many miles of Tesla range per hour one gets per level.

So, if you want the fastest power-up, always go with a Tesla supercharger. These power stations are incredibly efficient!

EV Speedy’s Take

Whether you’re charging your Tesla at home or at a supercharger location, you have no reason to worry if it’s raining outside.

Tesla chargers are waterproof and designed to stop charging if moisture does cause a short circuit.

Therefore, you and your Tesla are safe from the rain, so feel free to charge away!
