New energy charging piles can be used outdoors on rainy days. New energy charging piles are usually designed to be waterproof and can withstand a certain degree of rainwater intrusion. However, in heavy rainfall or stormy weather, it is recommended to avoid using the charging post outdoors to ensure safety. If you need to charge on a rainy day, you can choose to use the charging device indoors or in a sheltered area to avoid damage to the device caused by rain. It is also possible to charge in advance when rainfall is forecast to ensure that the vehicle has sufficient power for use.
