Troubleshooting a failed session
A calm sequence that resolves most public charging problems.
You'll learn
- Explain troubleshooting a failed session clearly and accurately
- Read the numbers that define the behaviour
- Apply the idea to a real charging session
Overview
Failed sessions are usually authorisation or handshake problems, not hardware faults. Work through them in order.
In depth
- 1Reseat the connector
Most handshake failures clear on a firm second attempt.
- 2Try a different authorisation route
App instead of card, or contactless instead of RFID.
- 3Try another post
Confirms whether the problem is the site or the car.
- 4Restart the vehicle
Cycling the car clears a stuck charge controller.
- 5Call the number on the post
Operators can remotely reset a unit within minutes.
Activity
Match the error to the fix
Authorisation failed
→Charging stops after a few seconds
→Post shows 'unavailable'
→Key takeaways
Remember this
- Reseat first — most failures are handshake related.
- A second post isolates car from site.
- Operators can reset units remotely.
