Are there any safety issues when charging new energy vehicles at outdoor charging stations in heavy rain? Below Bluesky will take you to find out.
1. How well-sealed is the vehicle?
In addition to worrying about water accumulation when driving in heavy rain, are you worried about too much rainwater leaking into the car?
Of course, you won’t worry, why?
Because the vehicle is very well sealed. Whether the vehicle is designed or assembled, it will take into account the tightness, and there will be a tightness test in the final factory test, which is called the rain test in the factory. The rain test is to install a high-pressure water gun in a tunnel of more than 10 meters in length and do a full range of spray tests on the vehicle, the density and pressure of the rain are far greater than the rainstorm you can encounter in normal driving. So a qualified vehicle that passes the rain test does not have to worry about its tightness.
Its charging interface also has a good sealing guarantee.
What you have to pay attention to is that when you plug in the charging joint, do not let the rain on the charging joint,
very simple, that is, you use an umbrella if it is stormy weather, the rain is aimlessly scraper everywhere,
this time it is not recommended that you go to the outdoor charging pile for charging,
because if there is rain on the charging head When the vehicle is charged, it will be detected, and if rain is detected,
the charge will not be filled. In simple terms, for the water resistance of the charging interface,
we can rest assured that even if there is accidentally rain dripping on it,
if there is a risk of leakage, the vehicle will prohibit vehicle charging through internal resistance detection,
so there is no need to worry about the risk of leakage. This situation can be said to be double insurance.
2. Charging piles have strict standards and regulations
Whether it is a public charging pile or a private charging pile, there are strict regulations. It has lightning protection, overload protection, short circuit protection, and leakage protection. Most of the current new energy vehicles have a waterproof design, especially since many charging ports are not directly exposed to rain, and charging piles are also designed to prevent rain, so basically you can rest assured of charging. If you are worried about charging on rainy days, the charging gun will have the problem of water short circuit, but in fact, the charging pile company will specially do waterproof treatment when designing the charging gun. The charging port of the electric vehicle is insulated and has a drainage design. After plugging in the charging gun, the charging port is in a sealed state. After the charging gun is correctly connected to the charging port, the waterproof function can be achieved.
In addition, China’s national standards stipulate that outdoor charging piles must reach the protection level of IP54,
and the construction of outdoor charging piles must strictly abide by the fire protection and lightning protection safety acceptance standards of charging piles. In addition, the charging pile should have a leakage protection switch inside the design.
Of course, if there is a canopy, charging is safer and more convenient. So now many places will build a canopy above the charging pile.
