Abstract
A portable battery pack and portable electronic device communicate by pulsing (turning on/off) their respective battery chargers causing variations in a magnetic field between the battery pack and portable electronic device that can be used to transmit and receive short messages through their respective coils using a magnetic communication protocol. Data or messages can be transferred between portable battery pack and portable electronic device when the portable battery pack and portable electronic device are in a mated configuration. The magnetic communication protocol allows for bi-directional communication of various battery status indicators and other data from the portable battery pack to the portable electronic device and vice-versa. The magnetic communication also allows the portable electronic device to be authenticated by the portable battery pack or vice-versa, such that the absence of any communication between the portable electronic device and portable battery pack renders the portable electronic device fully/partially inoperable.
