1. A fire spreading prevention system for a vehicle, comprising:
a battery state detector configured to detect battery state information for sensing a battery fire in the vehicle;
a controller configured to output a control signal for removing a battery upon determining that the battery fire breaks out using the battery state detector; and
a battery removal apparatus installed in the vehicle to fix the battery to a vehicle body, and configured to release the battery from the vehicle body and simultaneously to remove the battery from the vehicle in response to the control signal from the controller so that the battery is separated and removed to an outside of the vehicle so as to be spatially separated from the vehicle,
wherein the battery removal apparatus comprises:
a mounting structure rotatably installed on a vehicle body frame, configured to support the battery thereon, and rotated from the vehicle body frame due to a weight of the battery when the battery is removed; and
a locking device installed on the vehicle body frame to lock the mounting structure configured to support the battery and thus to fix the mounting structure to the vehicle body frame, and operated to release locking of the mounting structure in response to the control signal from the controller so as to rotate the mounting structure and to remove the battery, and

wherein the locking device comprises:
hooks rotatably installed on the vehicle body frame so as to lock engagement protrusions formed on the mounting structure; and
actuators fixedly installed on the vehicle body frame so as to forcibly rotate the hooks maintained in a locked state thereof to a lock release position.
