Battery pack monitoring system

摘要

An electronic device for monitoring the operating conditions of a rechargeable battery, and includes a temperature monitor for monitoring the operating temperature of the rechargeable battery; a voltage determiner coupled to the rechargeable battery for measuring the potential level of the rechargeable battery; a one wire interface for outputting the information corresponding to the potential level of the rechargeable battery and the information corresponding to the temperature monitored by the temperature monitor; and a power regulator coupled to the rechargeable battery for supplying regulated power from the rechargeable battery to the temperature monitor and the voltage determiner. The voltage determiner includes an analog to digital converter and utilizes a successive approximation technique to determine and output a digital value corresponding to the potential level of the rechargeable battery.
