1. Observation.
Observe the appearance of the charging pile line, generally speaking, the pure copper charging pile line has a smooth appearance, uniform color, no cracks and peeling, while the low-quality line is often rough on the surface, the wire diameter is not thick enough, and even some unscrupulous businesses use iron, aluminum or recycled materials to manufacture the charging pile line in order to reduce costs, which is often difficult to identify from the appearance, so it is more necessary for car owners to polish their eyes and be cautious when purchasing.
Second, the weighing method.
For people who are not familiar with the charging pile market, it is not recommended to use the weighing method to identify the material of the charging pile cable, because it is difficult to operate. However, if the owner has a professional electronic scale, he can judge whether it is pure copper by weighing the weight of the charging pile line. Generally speaking, the weight of the charging pile cable is directly proportional to its mass, if the weight of the charging pile cable is too light, or the copper wire of the charging pile wire is very thin, then it is likely not pure copper.
3. Resistance method.
The resistance method is a more professional identification method, and it is difficult for ordinary car owners to operate. By measuring the resistance value, you can judge the quality of the charging pile line, the smaller the resistance, the better the quality, and the purer it. Generally speaking, the heavier the weight and the smaller the resistance, the better the quality of the charging pile cable of the same length. If the charging pile wire is mixed with other metal impurities, the resistance will become larger, and the quality will be worse.
Fourth, smell the method.
If there is a peculiar smell, it is likely that there are impurities or oxidized odors inside. Generally, the pure copper charging pile line is tasteless.
5. Observe the color change.
If the charging pile cable has been burned by fire for a period of time, the color changes greatly, and you should also pay attention. The pure copper charging pile cable will change its color evenly after being burned, and it will appear orange-red. If the color changes blackened or purplish-red, then be careful.
In general, the above is the method to judge whether the home charging pile line of new energy vehicles is pure copper. When buying home charging pile cables for new energy vehicles, car owners must carefully choose purchase channels and merchants, and try to choose products from regular brands to ensure product quality and safety. At the same time, car owners also need to pay attention to the daily maintenance and maintenance of the charging pile line to ensure the safety and stability of the charging pile cable during use.
