Why Does My Charger Keep Cutting Out During Charging?

If your charger starts normally but then cuts out after a while, it usually means there’s an intermittent fault. The charger is designed to stop for safety if something isn’t stable.

Common reasons

  • Supply overload or voltage drop.
  • Loose or damaged cable connection.
  • Vehicle-side fault or software bug.

Steps to fix the issue

  1. Try removing the schedule,
    • Open the Simpson & Partners app.
    • Turn off/disable the schedule
    • If charging works normally in Imediate Charge mode, the issue may be with a smart charging schedule .
  2. Inspect the cable connection
    • Unplug and firmly re-insert the charging cable until it clicks.
    • Check for dirt, debris, or damage.
    • If you have another cable, test with that.
  3. Monitor your power use at home
    • Running big appliances (ovens, showers, heaters) at the same time can cause voltage drops.
    • Try charging when fewer appliances are in use.
  4. Test with another vehicle (if possible)
    • If the same issue happens with different vehicles, it’s more likely the charger or supply.

Quick summary

  • Charging that cuts out mid-session is usually caused by heat, supply issues, or a loose connection.
  • First, try manual mode and check the cable.
  • If the problem keeps happening, ask an electrician to check your supply or contact Simpson & Partners support.
