Precautions for connecting charging cables for electric vehicles
There are four charging connection methods for electric vehicle charging cables:
Charging mode 1: single-head charging gun + data cable + ordinary CEE plug connected to single-phase mains
Charging mode 2: single-head charging gun + data cable + control box + plug connected to single-phase mains
Charging mode 3: single-head charging gun + data cable + control box + plug connected to single-phase mains
Charging mode 4: combination of charging gun + charging cable + DC charging pile
The difference is: the difference between charging mode 2 and charging mode 1 is the addition of a controller. Compared with charging mode 1, charging mode 2 has complete protection measures, including overvoltage, undervoltage, overcurrent, overtemperature and leakage protection, while charging mode 1 has no protection measures. The first two modes are three-phase charging modes, and mode 3 increases the charging current, thereby increasing the charging speed and requiring higher charging safety. Charging mode 4 is a DC charging gun.
Of course, there are three ways of connecting an EV to a charging device. The charging cable is connected with the electric vehicle end, and can be plugged and unplugged with the grid end; the charging cable is connected with the grid connection end, and can be pulled out from the electric vehicle end; the charging line can be plugged and unplugged with the electric vehicle end and the grid connection end.
simple description:
1. The charging cable is connected to the electric vehicle end and can be pulled out from the grid end;
2. The charging cable has been connected to the power grid, and the EV can be unplugged;
3. The charging cable can be pulled out from the EV end and the grid-connected end;
The above charging methods, no matter what charging connection method is adopted, will be disturbed by natural and man-made environmental factors, which will affect the power transmission of electric vehicles.
About the natural environment: Most of the public electric piles of electric vehicle charging pile cables are outdoors. The cables are exposed outdoors for a long time. In the process of use, various harsh natural environments will be encountered, including large temperature difference between day and night, sunlight, weathering, humidity, acid rain, freezing rain, etc. These natural environments will inevitably be affected by electric pile cables, and the service life of cables and Performance can be degraded/degraded, and cables can be damaged, causing unnecessary loss and injury.
For artificial environment: During the use of the electric vehicle charging pile, due to its flexible use, it is inevitable that there will be artificial excessive bending, twisting, dragging or even stretching, which may easily cause mechanical damage to the charging cable; at the same time, the charging cable may be soaked. wet. In the artificial acid-base solution, it will affect the performance of the wire and cause damage to the charging ground.
The use environment of electric vehicle charging cables is relatively harsh. Therefore, higher requirements are placed on the flexibility, flexibility, mechanical properties and corrosion resistance of charging cables. Among them, the Omega electric steam charging line has an AC line - the basic performance comparison of European standard, American standard and national standard.
Also, choose cable length: In cable production, to learn more about our product quality and request free samples, you can send us your company details, including contact information, and the required specifications and quantities by email. For samples over 10 meters, please contact us for more information.
