Method and apparatus for providing electrical energy to a portable device from energy storage of another portable device
First Claim
1. A method, comprising:
- determining values of one or more parameters of a first energy storage in a first device and corresponding parameters of a second energy storage in a second device; and
setting a direction for transferring energy between the first device and the second device,wherein the direction of the energy transfer establishes that one of the first and second device is a source device and another is a target device, and the method further comprising;
determining, if the target device has an electrical load, whether the energy from the source device is to be directed to the energy storage of the target device, to the electrical load of the target device, or to be shared between the energy storage and the electrical load of the target device.

Abstract
A method comprises the steps of determining values of one or more parameters of a first energy reservoir in a first device and corresponding parameters of a second energy reservoir in a second device, and setting a direction for transferring energy between the first energy reservoir and the second energy reservoir. The direction may be set based on the voltage of the first energy reservoir and the voltage of the second energy reservoir, based on an input from a user, or based on the values of one or more parameters of the first energy reservoir and the second energy reservoir obtained in a device-to-device communication between the first device and the second device. A bi-directional charging interface for executing the method comprises two energy paths in opposite directions and a control unit for setting the direction for the energy transfer.

18. A bi-directional charging interface, communicatively coupled between a first device and a second device, comprising:
-
a first energy path, for transferring energy from a second energy storage in the second device to the first device; a second energy path, for transferring energy from a first energy storage in the first device to the second device; and a control unit, for determining values of one or more parameters of the first energy storage and corresponding parameters of the second energy storage, and for setting up a direction for transferring energy between the first device and the second device through either the first energy path or the second energy path, wherein the direction of the energy transfer establishes that one of the first and second device is a source device and another is a target device, and the interface further comprising; a status switching unit, operated by the control unit, for determining, if the target device has an electrical load, whether the energy from the energy storage of the source device is to be directed to the energy storage of the target device, to the electrical load of the target device, or to be shared between the energy storage and the electrical load of the target device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
