Real-World Scenario: Diagnosing an EV Charging Issue


Summary Answer: To troubleshoot an EV not charging properly, use an EV charger tester to simulate charging states and verify the EVSE connector’s functionality—this prevents unnecessary repairs and ensures compatibility with your vehicle.
  1. Identify the Problem: Your Tesla Model Y fails to start charging at a public AC station. Check if the vehicle shows “No Power” or “Charging Not Supported.”
  2. Use the EV Charger Tester: Connect the tester to the charging port. Set it to simulate charging state and enable pre-test mode to check signal integrity.
  3. Run Error Simulation: Activate error simulation to mimic common faults (e.g., cable resistance issues) and observe how the vehicle responds.
  4. Interpret Results: If the vehicle accepts the simulated charge but fails in real use, the issue lies in the station’s EVSE. If it rejects all tests, the vehicle’s charging port or software may be at fault.
  5. Take Action: Report the station issue to the operator or switch to a verified charging network.
