Charging an EV in the Rain: Myths, Facts and What You Really Need to Know

There are plenty of misconceptions about using electric vehicles in wet weather. Can they get damaged in the rain? Is it safe to charge them during a downpour? Is heavy rain or a car wash a risk? Here's what you need to know to put those fears to rest—and debunk the most common myths.

Just like petrol and diesel cars, electric vehicles undergo rigorous safety and waterproofing tests. These standards apply to high-voltage components including the cables, plugs and battery, making EVs safe to use even in the rain. The same goes for washing your car, whether by hand or in an automated wash—it’s safe for both user and machine.

Contrary to popular belief, EVs can be even more resilient to weather than internal combustion cars. The materials used in their construction are water-resistant: rubber seals, sealed housings, waterproof batteries and electric motors. Batteries are hermetically sealed during manufacturing to prevent contaminants from entering and to protect their internals. Manufacturers also adhere to strict waterproofing standards such as IP67, which guarantees protection even if the vehicle is temporarily submerged. And if water ever causes a short circuit or electrical fault, built-in safety systems instantly cut the current to prevent further damage and ensure driver safety.

As for lightning—no, EVs are not more likely to be struck. In fact, inside a car during a storm is safer than standing outside. The metal frame acts as a Faraday cage, guiding electrical energy around the cabin and keeping passengers safe. That said, it’s still best to stay inside the car during a storm.

Charging in the Rain

An electric car is an electrical device like any other, so it's reasonable to wonder whether it's safe to charge in the rain. The answer: yes. EVs are designed to handle wet conditions. If the cable isn’t securely plugged in, current won’t flow. Once connected, the plug and socket create a watertight seal that remains secure throughout the charging process. Charging components—cables, sockets, chargers—are all thoroughly tested to function safely in any weather, including heavy rain. Thanks to waterproof connectors that prevent water from touching live parts, there’s no risk of electric shock.

To charge your EV safely in wet weather, simply follow the safety and usage instructions recommended by your car’s manufacturer. These precautions are the same as for any electrical appliance—avoid contact between live wires and moisture. Never plug in or unplug your EV during a thunderstorm.

EV chargers are typically installed in covered parking areas or garages. But waterproof outdoor chargers are also available, with protection ratings of IP65 or higher, and will function even in rain. Even then, basic safety precautions still apply.

Public fast chargers and high-power charging stations are equipped with built-in safety checks. Before any current flows, the system runs an electronic check—if moisture has caused a short circuit, charging won’t begin. These safety features are part of the reason fast-charging costs more than home charging.

Key safety tips for charging an EV in the rain:
Don’t handle charging cables with wet hands or while standing in water
Don’t plug in a wet charging cable
Avoid charging during heavy rain or lightning storms
Don’t charge using a regular household socket
Don’t wash the car while charging
Don’t touch the charger, cables or socket with wet hands
Don’t use the plug or socket if they are wet
Don’t use charging points with cracked or damp enclosures
If moisture enters the vehicle’s charging port, don’t dry it with a cloth—instead, use a compressed air blower

With proper precautions, electric cars remain just as safe—and often safer—than traditional vehicles, even in the wettest conditions.
