Electric Vehicle owners or prospective owners want to know: Is it safe to charge my vehicle in wet or snowy conditions? Even if they don’t ask, they may be wondering, “Will I get shocked?” and “Is it dangerous?”
Those are good questions to ask because usually electricity and water do not mix. Normally, standing on a wet surface and plugging something in is a bad idea.
However, using EV charging equipment is usually safe to do in wet conditions. The Society of Automotive Engineers (SAE) designed and rigorously tested EV charging equipment to ensure safe charging in almost any weather conditions (it’s not advised during a hurricane or flood, for example). The car's electrical system is engineered to resist rain and water intrusion, as well as dust particles, all of which could damage it.
Reputable charging equipment systems should be engineered with the same precautions. After all, if they weren’t, EV enthusiasts could only charge their vehicles on a nice day.
That being said, there are some general charging station precautions to keep in mind.
Safe Electricity recommends following these EV charging safety tips:
- All components of a charging station should be in good working order. Look closely for signs of vandalism or disrepair.
- Although it sounds obvious, never use an EV charger if it is off its base or otherwise damaged, which could be caused by a natural disaster, major construction mishap or other type of accident.
- If you are considering having a Level 2 charging station installed at home, make sure it is certified by a reputable and independent testing laboratory (or purchased from the car manufacturer) and professionally installed. (Level 1 charging requires a regular outlet. Level 2 equipment is more complicated and requires a 240v outlet.)
- Always follow manufacturer’s directions when charging your vehicle.
- Place charging components up and out of reach when not in use.
- If you have an at-home unit in a carport or exposed area, make sure the outlet is covered so that water does not get inside the outlet.
Note: Level 3 changing stations, which fully charge an EV in about an hour or less, are usually offered at public charging stations.
