Abstract
A battery pack includes a battery cell, a current converting unit connected between the battery cell and a load and converts a discharge current of the battery cell, and a microcomputer that determines an amount of a discharge current of the battery cell and controls the current converting unit based on the amount of the discharge current. Accordingly, a current needed for the load may be adjusted in the battery pack.
Claims19
A battery pack comprising:
- a battery cell;
- a current converting unit connected between the battery cell and a load to convert a discharge current of the battery cell;
- and
- a microcomputer that determines an amount of a discharge current of the battery cell and a remaining capacity of the battery cell, and controls the current converting unit based on the amount of the discharge current and the remaining capacity of the battery cell.
1 more element
A battery pack, comprising:
- a battery cell;
- a current converting unit, connected between the battery cell and a load, to convert a discharge current of the battery cell;
- and
- a microcomputer to determine an amount of a discharge current of the battery cell and control the current converting unit based on the amount of the discharge current, wherein the microcomputer:
