Electric vehicle charging cable usage environment

China [CN]

The fight to protect the environment and the unification of charging connectors in the smartphone sector have resulted in many devices today without complete charging accessories. Electric cars are still far off, but now Tesla is ready to offer charging cables for an additional fee, although until recently they were not included in the delivery of electric cars.

The use environment and requirements of electric vehicle charging piles There are three connection methods for electric vehicle charging cables: the charging cable is connected to the electric vehicle end and is pluggable with the grid connection end; the charging cable is connected to the grid connection end and is pluggable with the electric vehicle end. ; The charging cable is pluggable with the electric vehicle end and the power grid connection end. The above charging connection methods, no matter which charging connection method they are, will be affected by the intervention of natural and man-made environmental factors, which will directly affect the power transmission of electric vehicles.

There are a number of challenges that exist for consumer adoption. As time goes by, consumers will not use electric car charging guns repeatedly, but will also wrap the cables, cover them, and expose them to the rain. Other factors such as lawnmowers occasionally running over them and dogs may bite them. The design must take into account these mechanical challenges for every part of the charging gun. They should include sturdy cable construction. Couple the stress reducer with appropriate strain relief to prevent copper wire breakage and cable insulation breakage.

Natural environment: Most public electric vehicle charging pile cables are outdoors. The cables are exposed outdoors for a long time. During use, they will encounter various harsh natural environments, including large temperature differences between day and night, sunlight, and weathering. , moisture, acid rain, freezing and seawater rain, etc. These natural environments will be affected, reducing the life and performance of the charging cable, and even weakening the reliability and safety of the charging cable, causing unnecessary losses and injuries.

Man-made environment: During the use of electric vehicle charging piles, due to their flexible use, excessive bending, twisting, dragging and even stretching will inevitably occur, which can easily cause mechanical damage to the charging cables; at the same time, the charging cables may be subject to artificial The resulting immersion in acid and alkali solutions affects the performance of cable materials and causes damage to the charging ground.

The use environment of electric vehicle charging cables is relatively harsh. Therefore, there are higher requirements for the flexibility, flexibility, mechanical properties and corrosion resistance of charging cables.

Among them, OMG electric vehicle charging cable has AC line---European standard, American standard, and national standard basic performance comparison. For details, please check the OMG official website for cable specifications. For search: https://www.omgevcable.com
