Charging an electric car in the rain is not dangerous

“Can the car charge when it rains?” is a question that many people still ask about the electric or plug-in hybrid vehicle segment. Companies say that charging when it rains is safe for people and vehicles, because electric vehicles and charging stations are thoroughly tested for safety under harsh conditions before they can be sold on the market. 

Water and electricity are a dangerous combination that can cause fatal accidents. Therefore, the vehicle’s battery and charging system are designed to be as watertight as possible, and integrate many additional technologies to protect against discharge, short circuit, etc. Each step of the charging process is carefully calculated to To protect the driver, electronic components must comply with strict rules set by safety organizations around the world, including the Ingress Protection (IP) standard, which indicates the level of dust/water resistance set. by the International Electrotechnical Commission (IEC). 

The IP standard represents the level of dust and water resistance of electronic components, and is widely used around the world. According to IEC 60529 standards, dust resistance is expressed through the first number, 1-6, water resistance is the next number from 1-8, the higher the number means the more resistant to dust/water factors. big. 

Normally, the IP rating of charging heads has a minimum level of IP54, which means it is dustproof and can withstand direct water splashes at any angle. More advanced product lines will have better weather resistance, such as IP68 standard charging guns, which can completely prevent dust from entering, and can be submerged underwater without being damaged. 

Public charging posts are also carefully designed and tested to withstand the test of time. In Vietnam, the included charger of VinFast electric vehicles has different waterproof ratings, including IP65 (controller), IP55 (charging when plugged into the vehicle), and IP54 (charging when not plugged into the vehicle). 

In addition to being waterproof, the charger and battery of electric vehicles are also designed to avoid discharge, or have a mechanism to stop charging when a short circuit or water intrusion is detected. These safety mechanisms are intended to protect customers as well as the vehicle’s battery, avoiding fires and explosions. 

Thus, the charging process for electric vehicles when it rains will not be different from when it does not rain. In case the charging pin or connection point is wet, charging may be stopped. At this time, the car owner needs to dry the charging head and try connecting again. Therefore, covering the charging car in the rain is not necessary.
