It is not recommended to charge the EV charger immediately after it has been rained for safety reasons. Rain can cause short circuits or damage to the circuit boards and electronic components inside the charger, which can cause electrical malfunctions or safety issues.
First of all, although the shell of the EV charger has some waterproof performance, it cannot completely resist the infiltration of a large amount of rainwater. Prolonged rain or heavy rain shocks can cause damage to the outer shell, which in turn allows moisture to penetrate inside. Once moisture enters the inside of the charger, the circuit board and electronic components can be corroded, resulting in reduced performance or damage.
Second, even if there is no visible damage to the charger on the outside, the circuit board and components on the inside may have been damaged. A humid environment can cause short circuits in electrical components, further damaging the charger and affecting the EV's electrical system. Therefore, even if the charger is able to work normally for the time being after rain, there are potential safety hazards.
If you need to continue using your EV charger after being exposed to rain, make sure it's completely dry. First, disconnect the charger from the electric vehicle and move it to a dry and ventilated place. Methods such as hair dryers or desiccant can be used to speed up the drying process, but avoid other safety hazards caused by overheating or improper use. Once you have made sure that the charger is completely dry, check it again to make sure that nothing is abnormal before you can continue using it.
In order to prevent similar situations from happening, it is recommended to choose a safe environment when charging. It's best to charge indoors, or use a protective measure such as a waterproof case or rain shelter when charging outdoors to ensure that the charger is not directly soaked by rain. This reduces the risk and extends the life of the charger.
To sum up, the EV charger cannot be guaranteed to charge normally after being exposed to rain, and there are certain safety risks. To ensure safe and normal use, the charger should be avoided in rainy days or unsafe environments, and checked again after making sure it is completely dry. At the same time, taking precautions to avoid rainwater soaking of the charger can effectively reduce the risk and extend the life of the charger.
