Problems with the charging cable

One of the most common reasons why an electric car may not charge is a problem with the charging cable. The cable used to charge an electric car connects your car to the charging station and transfers electrical energy. If this cable is damaged or has any defects, it can cause the charging process to stop or significantly reduce its efficiency.

Main causes of problems with the charging cable

Mechanical damage to the cable

Over time, the cable can become mechanically damaged due to frequent bending, pulling or improper storage. This can lead to damage to the insulation, reduced contact quality and even short circuits.

• Bending and stretching of the cable are common problems that occur when it is used incorrectly.
• Damaged insulation - can be dangerous as exposed wires can cause a short circuit or even a fire.

Problems with cable contacts

The contacts of the cable through which electrical energy is transmitted can become worn or corroded due to moisture or constant use. Poor contact between the plug and the connector may result in charging not starting or charging very slowly.

• Contact corrosion is the most common problem, especially if the cable is not stored properly.
• A poor connection to the charging station or vehicle connector can also be the reason why charging is not taking place.

Faults in the supply cables

Damage inside the cable, such as broken wires or damaged connections, can be difficult to detect without professional equipment. However, such faults can stop the charging process completely.

• Wire breaks or loss of connection inside the cable can go unnoticed, but lead to a complete lack of charge.
• Overheating of the cable due to overvoltage is also a common reason why charging fails.

Wear or defects in the plug itself

The plug that connects to the vehicle may become mechanically damaged or worn over time. This can cause the cable to not connect properly to the vehicle, which can also prevent charging.

• Damage to the plug can cause a loss of contact and stop charging.
• If the plug is cracked, scratched, or otherwise defective, charging will not work properly.

Problems with cable compatibility

There are different standards for charging cables, and it is important to make sure that the cable is suitable for your electric vehicle and charging station. Choosing the wrong cable or using an incompatible type may result in no charging taking place. For example, different connectors (e.g. Type 1 and Type 2) are used in different car models, and mismatching the cable type can prevent charging.

How to solve problems with the charging cable

• Inspect the cable for damage. Before starting the charging process, check the cable for visible damage. Damage to the insulation, breaks, or signs of overheating may be evident when you examine the cable closely. If you notice any defects, be sure to replace the cable.
