Is it okay for an electric vehicle charger to get wet in the rain?
2 Answers
Getting an electric vehicle charger wet in the rain may cause water ingress, which can easily lead to the charger burning out. Below are the specific classifications of batteries (also known as accumulators): Conventional Battery: The plates of a conventional battery are made of lead and lead oxide, with the electrolyte being an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost; the disadvantages are low specific energy (i.e., the amount of electrical energy stored per kilogram of battery), short service life, and frequent maintenance. Dry-charged Battery: Its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high electricity storage capacity. In a completely dry state, it can retain the stored electricity for up to two years. When in use, you only need to add the electrolyte and wait for 20-30 minutes before it can be used. Maintenance-free Battery: Due to its structural advantages, the maintenance-free battery consumes very little electrolyte and basically does not require the addition of distilled water during its service life. It also features shock resistance, high-temperature resistance, compact size, and low self-discharge. Its service life is generally twice that of a conventional battery.
Charging an electric vehicle in the rain does pose risks. I've personally witnessed cases where exposure to rain caused short circuits or equipment damage while driving. Although many chargers are designed with waterproof features like IP65 ratings, this isn't foolproof—rainwater can still seep into internal circuits and cause malfunctions. If water gets inside, not only could the charger be ruined, but there's also a risk of electric shock and potential damage to the vehicle's battery. I recommend choosing sheltered charging locations, such as spots with rain covers or using specialized waterproof covers. If the charger does get wet, avoid immediate operation—first unplug it and wait until it's completely dry before attempting to use it again. During regular maintenance, check that charging ports are properly sealed to prevent frequent issues during rainy seasons. This approach not only saves money but also ensures safety.
