Energizer Wiimote Induction Charger Teardown

Energizer Wiimote Induction Charger

An inductive charger is a type of wireless energy transfer system, it can also be called an air core coil transformer. It works by passing alternating current into the coils and air acting as a medium between them, the interacting electromagnetic field helps to induce inductive coupling. Wikipedia does a much better job of explaining it: Inductive Charging.

In this teardown, I’ll be featuring the Energizer Wii Inductive charger (model # PL-7581) and try to figure out how it works internally. This will be a challenging on-going project since some key IC components have been blackened for a reason to keep their functionality secret. I would like to add that throughout this teardown, I have come to appreciate the complexity of this device and commend Energizer for a job well done, they did their homework.
