Battery pack and method of driving the same

A battery pack, comprising:

• a battery to supply power for a device;
• a battery management system (BMS) to manage the battery;
• and
• a signal line to transfer a turn-off command from an external host system to the BMS, wherein the BMS is to generate a control signal to block transfer of a control current from the battery to the BMS based on the turn-off command.

A method for driving a battery pack, the method comprising:

• providing the battery pack;
• and
• turning off a battery controller based on a turn-off command,
• wherein turning off the battery controller includes receiving the turn-off command from an external host system, receiving information corresponding to a battery, and generating a control signal to turn off a switching circuit, and when one or more predetermined conditions are satisfied and a control current from the battery to the battery controller is blocked, the control current to the battery controller is turned off based on an off state of the switching circuit.

An apparatus, comprising:

• at least one signal line;
• and
• a controller coupled to the at least one signal line to control a battery,
• wherein the controller is to generate a control signal to block receiving a control current from the battery based on a turn-off command from an external host system when one or more predetermined conditions are satisfied.
