1. A battery pack, comprising:
- a battery cell;
a charge-blocking unit;
a voltage sensing and balancing circuit; and
a microcomputer, the microcomputer including a controller configured to detect at least one selected from the group of abnormal analog-to-digital conversion, abnormal voltage, and abnormal temperature of the battery cell, the controller configured to output a charge control signal to the charge-blocking unit to inhibit charging of the battery cell.
