Battery pack including plurality of current paths

A battery pack including a plurality of current paths, comprising:

• a battery module comprising one or more battery cells;
• a diode disposed such that a direction toward a positive electrode of the battery module is a positive direction, the diode being connected in parallel with the battery module;
• a FET (Field Effect Transistor) comprising a gate terminal, a drain terminal, and a source terminal, connected in parallel with the diode through the drain terminal and the source terminal and connected to the other end of the diode through the gate terminal, the FET being configured to receive an operation voltage from the battery module through the diode;
• a first transistor comprising a first base terminal, a first emitter terminal, and a first collector terminal, the first base terminal being connected to the drain terminal, the first emitter terminal and the first collector terminal being connected to a positive electrode terminal of the battery module;
• and
• a second transistor comprising a second base terminal, a second emitter terminal, and a second collector terminal, the second base terminal being connected between the drain terminal and the first base terminal, the second collector terminal being connected to the first emitter terminal, the second collector terminal being disposed between the first emitter terminal and the first collector terminal, and the second emitter terminal being connected to the first collector terminal,
• wherein the first emitter terminal is connected between the positive electrode terminal of the battery module and the second collector terminal of the second transistor.
