State Grid Beijing Electric Power Company: In the face of rainy weather, especially heavy rain, many people's friends and WeChat groups will receive the news: charging piles and utility poles will leak electricity, away from rainy days. Of course, this is a rumor.
Heavy rain weather using charging piles is unsafe and may leak
During the construction of the charging facility, ground hardening and basic protection will be performed at the bottom of the charging facility, making the 20-30cm capacity below the charging pile body to prevent overflow. National standards also have strict safety requirements for charging interfaces. The vehicle side and the pile side must be insulated before charging begins. If the insulation test fails, charging cannot be started. After charging connection, the overall IP rating requirements to reach IP56, that is, any angle spray waterproof, generally rain will not be a problem. Finally, the charger side design is short-circuit edited. If the charging process is shorted, the device will cut off the charging current for the first time.
Despite the above safety measures, The State Grid Beijing Electric Power Company advises you to avoid rain for your safety. Second, before charging the connection, check the pile side connector side and side connector for water or foreign body, and then connect after cleaning or wiping. The third is to charge the connection when it rains. During the connection, use an umbrella or other item to shield. Fourth, if you find heavy rain and flooding at the charging station, don't rush the charging pile to avoid electric shock.
