ELECTRONIC DEVICE STATE DETECTION FOR ZERO POWER CHARGER CONTROL, SYSTEMS AND METHODS
First Claim
1. An energy management control for an electrical device powered by a mains power supply via a cable including a power line and at least one signal line,the control comprising:
- a processor-based device;
converter circuitry configured to supply output power to the power line in the cable when the cable is connected to the electrical device; and
a switch operable by the processor-based device to connect or disconnect the mains power supply and the converter circuitry;
wherein the processor-based device is configured to monitor a voltage of the at least one signal line to determine whether the cable is connected or disconnected to the electrical device, and to operate the switch to disconnect the mains power supply and the converter circuitry when the cable is determined to be disconnected from the electrical device.

Abstract
A charger appliance configured to determine a no-load, disconnected state from an electronic device having a rechargeable battery, and configured to determine a connected state of the charger with an electronic device in which recharging power may be supplied through the charger to the electronic device. Automatic connection and disconnection of a mains power supply is made depending on the detected state of the charger to avoid wasteful energy consumption in a no-load state. State detection may be determined by monitoring a voltage on one or more signal lines associated with the electronic device.
