Ensure the vehicle is in a safe location and the charging cable is disconnected.

Visually check the charging cable for any cuts, frays, or kinks.

Plug a different device into the same outlet to ensure it is functioning correctly.
If using a public charging station, try a different station to rule out issues with the original.
