How to choose the cable for the home AC charging pile？
Usually, the cable specifications of the car charging pile are large and small, and when we install the charging pile,
the choice of cable should fully consider the power size and flow capacity of the charging pile.
The thickness of the wiring harness of the charging pile can not be unified,
mainly by the charging pile’s electrical storage capacity and the voltage borne by the wiring harness in the circulation of electricity to determine,
in general, whether the charging pile wire is much thicker than other wires.
When choosing a household new energy vehicle charging pile cable, we need to consider the following factors,
voltage level, charging pile power, and PowerPoint distance.
For the household charging pile, it is an AC pile, and the voltage level is 220 volts,
if the charging pile power is 7 kW, we need to use three core six square pure copper cables,
model YJV3*6 square, if the PowerPoint distance is more than 200 meters,
you need to consider the use of three core + square, model YJV3*10 square cable.
When we use three-phase electricity, the voltage level is 380-volt cable,
you need to choose five core ten square pure copper cable, model YJV5*10 square,
of which five core cables are three live wires, one neutral wire, and one ground wire.
In addition, we can also choose to use aluminum core cables,
but for the safety of electricity, when using aluminum core cables, the cable needs to be increased by two numbers,
and finally, in order to ensure the safety of electricity,
it is recommended that we use cables produced by regular manufacturers.
Different brands of charging piles have different regulations, according to the requirements of the brand.
Some may ask why the longer the distance, the thicker the line.
Because the cable also has resistance, the farther the distance, the greater the resistance,
and the thicker the cable is used to reduce the resistance and ensure the current, that is, to ensure the charging power.
How to choose the material?
Some charging pile cables on the market will crack under low-temperature conditions,
the selection of charging cables should choose the outer insulation, the sheath using thermoplastic elastomer insulation TPE,
and strong temperature resistance, even in the cold winter can maintain good elasticity,
no cracks do not crack, to meet the requirements of cold areas. The selection of cable needs to consider the characteristics of UV resistance,
ozone resistance, chemical erosion resistance, and weather resistance, and has the mechanical properties of special bending, bending,
and vehicle rolling experiments, and can be used well to adapt to various harsh environments, long service life, and other advantages.
Factors such as vehicle type, charging power, and installation environment need to be considered when selecting charging cables to ensure that the selection of cables meets the requirements of charging piles and can achieve safe, fast, and efficient charging. At the same time, in order to ensure the safety of charging, the installation of the charging pile cable needs to be carried out in strict accordance with the specifications, and professionals will conduct installation testing.
