In today's era of widespread electric vehicles, the safety of charging stations is crucial. Many people probably have a question in their hearts: What are the technical parameters and standards for waterproof testing of charging piles? This directly relates to the safety of using charging stations in complex outdoor environments.

The waterproof testing of charging piles is based on different standards and has a series of strict technical parameters. Common examples includeThe IP protection level standard, including IPX4-IPX9K, is commonly used for waterproof testing of charging stations.

When conducting IPX4 level testing, the water flow rate of the waterproof testing device for the charging pile should reach 10 ± 0.5L/min. During the testing process, the charging station needs to be placed on a rotating platform and rotated at a speed of 0.5-1r/min, fully accepting splashing water and simulating daily splashing scenarios. The testing time is calculated at 1 minute per square meter and should not be less than 5 minutes.

IPX5 level test, the nozzle inner diameter of the device is generally 6.3mm, the water flow rate is stable at 12.5 ± 0.625L/min, the water pressure is maintained at 30-150kPa, and the commonly used pressure is 80-100kPa. The distance between the nozzle and the charging station is 2.5-3m, in all directionsnoodlesSpray water 360 °, with a minimum spraying time of 3 minutes on each surface, to test the charging station's ability to withstand a certain pressure spray.

IPX6 rating, nozzle inner diameter increased to 12.5mm, water flow rate increased to 100 ± 5L/min, water pressure significantly increased to 1000-1500kPa. Similarly, all aspectsnoodlesSpray water to simulate a more severe water spraying environment, ensuring that the charging station is in good conditionsevereThe waterproof performance is reliable under certain conditions.

The IPX9K rating requires more stringent requirements, with water temperature heated to 80 ℃± 5 ℃, water flow rate of 14-16L/min, and water pressure of 10000-1000kPa. Spray specific parts of the charging pile from four angles: 0 °, 30 °, 60 °, and 90 °, with a spraying time of no less than 30 seconds at each angle, simulating high-pressure and high-temperature cleaning scenarios.
