List of common issues with household charging cables

Household charging cables may encounter the following common problems during use:

1. Cable wear and damage:

Skin wear:

Long term friction, dragging, bending, scraping, etc. may cause the outer skin of the cable to wear and expose the internal wires, increasing the risk of short circuits and electric shock.

Interface damage:

Frequent plugging, improper operation, and mechanical impact may cause damage to the cables at the charging gun interface or charging station interface, such as bent or broken pins, poor contact, etc.

2. Cable overheating:

Excessive current:

If the cable specifications are not selected properly and the current carrying capacity is insufficient to support the actual charging current, it may cause the cable to overheat.

Wire diameter mismatch:

The wire diameter is too thin or the cable quality is poor, the resistance is high, and excessive heat is generated during long-term high current charging.

Poor heat dissipation:

The cable layout is too dense, poorly ventilated, or the external environment temperature is too high, which affects cable heat dissipation and exacerbates overheating.

3. Water intrusion:

Sealing failure:

The sealing components at the interface of the charging gun and cable joints are aging or damaged, and rainwater, moisture, etc. enter the interior of the cable, causing insulation degradation or even short circuits.

Environmental impact:

When used in damp, rainy, and humid environments, or when cables are directly immersed in water, it can lead to water intrusion.

4. Electrical fault:

Poor insulation:

The insulation material inside the cable is aged or damaged, resulting in short circuits between wires or leakage to ground.

Loose joints:

The connection at the cable joint is not secure, the contact resistance increases, and the heating is severe.

Abnormal control signal:

For cables with communication functions, there may be signal transmission failures, leading to charging interruptions or inability to start.

5. Improper installation and use:

Inappropriate cable length:

The cable is too long or too short, which affects the convenience of use or leads to excessive voltage drop and reduced charging efficiency.

Loose cable fixation:

The cable laying is disorderly, without proper fixation, and is easily pulled or worn by external forces.

Cable selection error:

Not selecting appropriate specifications of cables based on charging station power and vehicle charging needs.

6. Environmental factors:

UV aging:

Outdoor cables exposed to sunlight for a long time may cause aging and embrittlement of the outer skin material.

Chemical erosion:

Contact with corrosive substances such as oil, acid, and alkali can affect the insulation and mechanical properties of cables.

Animal bites:

In certain environments, rodents or other animals may bite through the outer skin of cables, causing safety hazards.

7. Quality issues:

Raw material defects:

The use of inferior conductors or insulation materials in cables results in low performance and short lifespan.

Poor production process:

During the cable manufacturing process, there may be issues with loose joint welding and uneven insulation layer thickness.

To solve these problems, it is usually necessary to regularly check the condition of the cables, replace damaged parts in a timely manner, ensure the correct installation and use of the cables, and choose charging cable products that are reliable in quality and meet standards when purchasing. When encountering complex problems, it is recommended to seek the help of professional technical personnel.
