By thoroughly inspecting the charging cable for any signs of damage, such as cuts, cracks, or exposed wires, it is possible to identify potential issues that may be hindering the charging process.

To check the charging cable:

  • Turn off the car and unplug it from the charger.
  • Inspect the entire length of the cable for any visible damage, such as cuts, frays, or exposed wires.
  • If you notice any physical damage on the cable, stop using it immediately and replace it with a new one.
  • Check for any kinks or twists in the cable, as they can cause internal damage over time.
  • Ensure that all connectors are clean and free from corrosion, as this can affect power transmission.
