Mobile communication device comprising a smart battery system

摘要

A mobile communication device utilizes a smart battery (130) and includes a main processor for controlling the operation of the mobile communication device. The smart battery (130) is coupled to the main processor and provides supply power. The smart battery (130) includes a battery processor (252) for controlling the operation of the smart battery (130) and communicating with the main processor, and a battery module (262) having one or more batteries for providing the supply power. A battery interface (256) is provided for coupling between the main processor and the battery processor (252) for providing communication therebetween. The battery interface (256) comprises a data communication line and protection circuitry for protecting the main processor from electrostatic discharge. A communication protocol is also provided for communication between the main processor and the battery processor (252).
