METHOD AND APPARATUS FOR COMMUNICATION BETWEEN AN ELECTRONIC DEVICE AND A CONNECTED BATTERY

摘要

An apparatus supporting both identification of a battery type and communications over an interface between a battery and an electronic device is disclosed. The electronic device includes a processor for communicating with communications circuitry of the battery. Identification circuitry associated with the processor enables a determination of the type of battery with which the electronic device is connected. If a "smart" battery capable of carrying out serial communications with the electronic device is connected, the electronic device further provides means for carrying out communications between the processor and the communication circuitry of the battery.
