Charging has
an end.
Power should too.
BrightZero monitors charging behaviour and cuts power at the source when normal charging is effectively complete.
Illustrative operating principle · Simplified charger integration
The right moment.
The right place to stop.
Charging can finish long before we unplug. BrightZero brings control to that final part of the routine.
Follow the charging.
BrightZero monitors charging behaviour from the power-source side while the connected device charges.
Recognise the finish.
It identifies when normal charging is effectively complete, based on the observed charging behaviour.
Stop at the source.
Power is cut automatically. The device stays physically connected, while the charging power feed stops.
Concept sequence. The cut-off point depends on device settings, battery characteristics, charger behaviour and the application.

The technology.
In your hands.
BrightZero Smart Plug brings automatic source-side cut-off to everyday charging. A practical starting point for product evaluation, distribution and white-label discussions.
Understand the details.
What does “effectively complete” mean?
For BrightZero Smart Plug, charging typically stops at approximately 90–100% state of charge. The result depends on device settings, including optimised charging, battery characteristics and charger behaviour. Integration requirements are assessed for each application.
Does BrightZero replace the battery’s own protection?
No. BrightZero monitors charging from the source side. It does not monitor the battery’s internal condition or replace the device’s battery management system (BMS) or the charger’s protection functions. It may not detect every battery or charger fault. Follow the product, device and charger safety instructions.
