Abstract

A battery pack includes at least one battery cell, a microcomputer having a first voltage measuring terminal, a second voltage measuring terminal, and a reference voltage output terminal, the microcomputer being configured to control recharge and discharge of the at least one battery cell by detecting an abnormality of a reference voltage at the reference voltage output terminal in accordance with first and second voltages at respective first and second voltage measuring terminals, a voltage distribution unit connected between the reference voltage output terminal and a ground, the voltage distribution unit being configured to distribute voltage and to output to the microcomputer a medium voltage as the first voltage, and a voltage measuring unit connected between the reference voltage output terminal and the ground, the voltage measuring unit being configured to output to the microcomputer a forwarding direction voltage of a diode as the second voltage.
