Abstract

A battery system includes intelligence to allow the battery system to control various aspects of the charging and discharging of the battery, as well as to constantly monitor the battery voltage, temperature, current charge/discharge rate, and remaining capacity of the battery. The intelligent battery system is capable of being charged from a simple voltage supply, with all aspects of charge/discharge rate control and monitoring being accomplished as a function of the intelligent battery system itself, rather than as part of an external charging circuit, or an external electronic device to be powered by the intelligent battery system. This alleviates the need for external systems to include such circuitry and control elements and allows, if desired, a variety of intelligent battery systems to be developed for use with a given electronic system or family of electronic systems, with each battery being able to control its own charge/discharge rates and monitoring functions. The intelligent battery system is capable of communicating with an external device such as a computer powered by the intelligent battery system, in order to provide an indication of the charge/discharge rate, the s…
