1. A battery pack, comprising:
- a plurality of battery cell groups including a first battery cell group and a second battery cell group;
a first switch connected to the first battery cell group;
a second switch connected to the second battery cell group; and
a controller to selectively control charging and discharging operations of the first battery cell group and the second battery cell group using the first switch and the second switch, whereinwhen a capacitance of the first battery cell group is greater than a capacitance of the second battery cell group, the controller controls the charging and discharging operations of the first battery cell group first.

12. A battery pack, comprising:
-
a plurality of battery cell groups including a first battery cell group and a second battery cell group, the second battery cell group having a greater capacitance than that of the first battery cell group; a first switch connected to the first battery cell group; a second switch connected to the second battery cell group; and a controller to selectively control charging and discharging operations of the first battery cell group and the second battery cell group using the first switch and the second switch; a PTC element connected between the second battery cell group and the second switch; and a diode connected in parallel to the PTC element and of which an anode is connected to a positive side of the second battery cell group and of which a cathode is connected to the second switch.

13. A battery pack, comprising:
-
a plurality of battery cell groups including a first battery cell group and a second battery cell group; a first switch connected to the first battery cell group; a second switch connected to the second battery cell group; and a controller to selectively control charging and discharging operations of the first battery cell group and the second battery cell group using the first switch and the second switch; a first analog front end (AFE) circuit to detect a remaining battery amount of the first battery cell group; and a second AFE circuit to detect a remaining battery amount of the second battery cell group, wherein the controller controls the charging and discharging operations of the first battery cell group and the second battery cell group based on the remaining battery amount of the first battery cell group and the remaining battery amount of the second battery cell group obtained by the first AFE circuit and the second AFE circuit, respectively. - View Dependent Claims (14, 15, 16, 17, 18)
