BATTERY PROTECTIVE CIRCUIT AND BATTERY PACK COMPRISING SAME

A battery protective circuit may include: a first switch connected between a negative pack terminal of a battery pack and an output node to control an electrical connection between the negative pack terminal and the output node; a first resistor connected between the output node and a ground; and a controller configured to control on or off of the first switch and to determine a short circuit state between pack terminals of the battery pack based on an output voltage of the output node.
