Are Electric Vehicles Safe to Charge During Thunderstorms? Can EV Chargers Work in the Rain?

Theoretically, electric vehicles (EVs) charging during thunderstorms shouldn't be a cause for concern. From a vehicle standpoint, the charging system is designed with waterproofing, battery safety, and overall insulation in mind. Additionally, with the vehicle's tires made of rubber, they act as insulators when in contact with the ground.

Moreover, the vehicle body, being made of metal, can create a Faraday cage when doors and windows are closed. This enclosed space provides a measure of safety during thunderstorms, making it safer to be inside the vehicle rather than outside. As long as one avoids contact with the metal parts of the vehicle, including during the charging process, it's generally safe to shelter from thunderstorms inside an EV.

Furthermore, the majority of charging stations, whether branded home chargers or third-party installations, incorporate multiple safety features against lightning and electrical leakage. This explains why charging stations are often installed outdoors and can withstand various weather conditions.

While theoretically, EV charging in the rain and thunderstorms is feasible, and both vehicles and charging facilities are built to withstand such conditions, it's essential to observe the following precautions:

1. Ensure Tight Connection: Confirm a secure connection between the charging gun and the vehicle's charging port to prevent electrical leakage due to poor contact.

2. Waterproof Charging Equipment: Despite being waterproof, it's advisable to use umbrellas, raincoats, or plastic covers to shield charging equipment from rain to avoid potential malfunctions due to water ingress.

3. Keep Charging Equipment Dry and Clean: Maintain the charging port and gun dry and clean, removing any water stains or foreign objects promptly.

4. Avoid Charging in Open Areas: Thunderstorms increase the likelihood of lightning strikes in open areas. It's best to avoid charging in overly exposed locations during rainy and stormy weather.

5. Choose High-Elevation Charging Spots: On rainy days, opt for charging spots with higher elevations to prevent potential flooding of the vehicle's battery pack due to water accumulation in low-lying areas.

While charging an EV during thunderstorms is generally safe when following proper precautions, it's essential to remain vigilant and prioritize safety in adverse weather conditions.
