Abstract

Various embodiments are described herein for a mobile communication device that authenticates a smart battery prior to use. The mobile device includes a main processor and a device memory. The device memory stores first and second portions of security information used for authentication. The smart battery includes a battery processor and a battery memory. The battery memory stores a third portion of security information used for authentication. The main processor sends an authentication request including the first portion of security information to the battery processor, and the battery processor generates a response based on the first and third portions of security information and sends the generated response to the main processor. The smart battery is authenticated if the generated response matches the second portion of security information.

Description

[0001] Comparison of related applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 726,164, filed October 14, 2005. technical field [0003] Embodiments described herein relate to a mobile device that includes a smart battery. Background technique [0004] Peripheral devices such as mobile wireless devices or personal data assistants may be powered by internal means such as internal battery packs. An internal battery pack is a collection of one or more cells and provides a certain amount of storage. Different battery packs have different storage capacities, different terminal voltages (eg, 4.2V and 4.4V), and different charging / discharging characteristics. Typically, the battery pack contains a battery ID resistor to indicate the battery type, from which the battery pack's storage capacity can be ascertained. [0005] The amount of storage and the type of battery are important for a variety of reasons. For example, if t...
