Abstract:
1. An upgradable Self-Monitoring Analysis and Reporting Technology (SMART) battery pack, comprising: a battery array; a host interface for supplying power to a host and performing a SMART communication with said host; a protection circuit for protecting a battery cell in said battery array from overcurrent or overvoltage; a microprocessor for monitoring a current state of said battery array, calculating a battery capacity of said battery array and controlling said SMART communication between said host and said host interface; a memory for storing an operational program of said microprocessor and battery information; a signal processor for converting a level of a signal to be sent to said host via said host interface into a predetermined level that is desired by said host and processing the level-converted signal; and an input/output port for performing an interfacing operation between said host and said microprocessor to download a control program and data from said host; wherein said input/output port includes: a reset terminal for erasing data stored in said battery pack in response to a control signal of said host; and a first serial output terminal for downloading said control program and data from said host to said battery pack.
