A complete list of daily safety precautions for charging piles
1.Is the charger head always charged?
The charging gun head is not charged when the charging is not started. The charging gun is only energised once it has been inserted into the vehicle charging port and certified for operation.
2.Charging posts should pay attention to rainproof design
Industry accepted water resistance for charging facilities should be at least outdoor IP54 rated, which means that they are waterproof when sprayed at any angle. So generally when it rains, charging facilities will not have problems due to water ingress.
During the construction of charging facilities, ground hardening and foundation protection are carried out at the bottom of the charging facility to make the charging pile 20-30 cm below the body of the pile resistant to flooding.
The charging ports of public charging posts are usually designed to be recessed and surrounded by an insulating seal with a drainage design.
The charging gun is also insulated between each hole and rainfall has no effect on charging.
Outdoor charging facilities are built with canopies where possible.
3.Charging posts should be equipped with lightning protection
Charging piles have lightning arrester devices installed to prevent damage to equipment struck by lightning. It is best not to use the charging pile for charging during lightning and thunder, especially in the open air where there is a great danger. This is because when charging new energy vehicles, the charging line in working condition will transmit a large amount of current, especially when it rains, the wire will be in a wet state, with a certain degree of conductivity. In the event of a lightning strike, there is a high risk that the charging pile will be struck. Despite the fact that the charging post is connected to the ground, a strike on the charging post could generate a significant amount of current and voltage, which would be dangerous.
However, charging indoors is perfectly possible, and charging in a house is protected from lightning strikes by a lightning rod.
4.Charging posts should be equipped with earth leakage protection
The charging pile is designed with double leakage protection, and the charging pile and the power supply are equipped with a leakage protection device, so that in case of leakage, the power can be disconnected in time in the charging pile or in the power supply box and the power supply can be stopped.
5.The charging pile should be equipped with an emergency pause button
The charging pile should be equipped with an emergency stop button and installed in a conspicuous position. In the event of a dangerous moment, pressing the emergency stop button can cut off the output switch to stop charging in 100 milliseconds.
6.The charging pile should be matched with a fire extinguisher, or even come with its own intelligent fire extinguishing device
The charging pile should be matched with a fire extinguisher at the time of construction, and the charging pile should also be equipped with an automatic fire extinguishing device inside if conditions allow, which is now a mature technology and can be widely used.
