If your car is charging beyond the limit set in the Octopus app, it’s because the charge limit is not controlled by the app or the Simpson & Partners charger — it must be managed by your vehicle directly.

Why This Happens

• The Octopus Intelligent tariff controls when your car charges, not how much it charges.
• The Simpson & Partners charger delivers energy during allowed charging times but cannot stop charging at a certain battery percentage.
• Only your vehicle can limit the charge level. Neither the Octopus app nor the charger can override this.

How to Fix It

1. Set the Charge Limit in Your Vehicle
   Most electric vehicles allow you to set a charge limit using the in-car display or manufacturer’s app (e.g. Tesla app, MyBMW, Kia Connect).
2. Ensure the Limit Is Saved
   Some vehicles require you to confirm or re-activate the limit each time you plug in.
3. Observe the Next Charging Session
   After setting the limit in your vehicle, monitor the next charge session to confirm that charging stops at the correct battery level.

Troubleshooting

How do I know if the charge limit is active?
Check your vehicle’s settings or app to confirm the limit is enabled before charging. Some vehicles default to 100% unless a new limit is saved.

Can the Octopus app override my vehicle’s limit?
No — Octopus controls the timing, but your car controls the battery level. For safety and technical reasons, only the vehicle can stop charging at a specific percentage.

Summary

The charge limit must be set directly in your vehicle.
While Octopus Intelligent controls when to charge, it cannot limit how much.
To prevent overcharging, always set and confirm the limit within your car’s own settings.
