“Is it safe to charge my electric car in the rain?”



We all know that water conducts electricity, so shouldn’t we be concerned that charging your car in the rain is like swimming in a lake during a thunderstorm?  Fortunately, electric car chargers are weatherproof and are specifically designed to protect both the car and its humans from electrical shock.  Electric vehicle chargers are rigorously tested by OSHA-certified laboratories and have to meet stringent safety standards set by the Society of Automotive Engineers. Before an OEM can use just any old part, it needs to be tested. Waterproofing electrical connectors is pretty routine. They even have to pass fire hose testing where the connector is subjected to high pressure spray.

Furthermore, “federal law requires manufacturers to test many consumer products for compliance with consumer product safety requirements. Electric shock is among them.” (visit for more information)

So if you find yourself in the rain with your electric car, don’t give plugging in a second thought.

It’s totally safe.

    @Courtney, same here, I charged my Leaf overnight in a rainstorm and when I went to start it in the morning it had no power. Towed it in and the 12-volt battery had been shorted out and the service guy said disapprovingly to me that the charger was “full of water.” I was gobsmacked that the system wasn’t more robust re: waterproofing, especially after reading all the expert answers saying how rigorous the testing is. True, I didn’t get electrocuted or anything, but I did fry the battery. I had only had the car for 8 days – took two to repair it. I am about to go pick it up and am hoping there is no lasting damage.

    Our 2018 Chevrolet Bolt EV goes 300 miles in the summer and only 160 miles in the winter. We drive it a lot in the summer , not so much in the winter. We have a level 2 charger in our garage.

  3. Adrian Shipley says:

    Chevy bolt goes 238 miles on a full charge and can extend the range with regeneration braking helping while avoiding climate control use in the car. Outdoor temperature can effect the battery need to cool or heat for operating

  4. Adrian Shipley says:

    Commercial chargers are safe in the rain household outlets are not advisable during a rainstorm

  5. Courtney says:

    Except when it’s not. My charger is now nonfunctional because I charged my car in the rain.

  6. Sherry Hoffman says:

    The charger sat in standing water (the actual plug that goes into the car port) Now my charger is beeping. Can you help?

  7. Jessica says:

    Our new Chevy Bolt gets 230 miles to the charge.

  8. Barbara Rush says:

    I plug my ev into an uncovered 110 outlet on the outside of my house. Is it safe to plug in in the rain?

  9. Derek says:

    Some cars that are partially electric have a range of only 20-30 miles while some all-electric vehicles can have up to a 150 mile range on a single charge. Just depends on the car.

    Maybe 25 years ago when using flooded PbA cells or some of the Nichel Iron or NiCad battery packs. All plug-in electric vehicles include a check to make sure ventilation is not required before charging begins. Vehicles requiring ventilation have not been offered for sale in the US for at least 20 years. As opposed to gasoline vehicle refueling, charging an electric vehicle can be done in doors.

  11. Rod says:

    Is it safe to charge an EV in a carport under a house or apartment? I have been told that the battery emit some kind of gas while charging.

  12. ARNOLD says:

    Has the RANGE of the cars improved much? What is the average current range?
